(Report on collecting wind and sketching)
After a long journey over mountains and mountains, we arrived at Hongcun-but we called for a thousand times and urged her for a thousand times before she came to us.
Arriving at Hongcun, the sky is gloomy, Huizhou mountains are magnificent, and the village at the foot of the mountain is silent. Layers of buildings are stacked in layers, and the towering horse head wall stands quietly, which is simple and beautiful. More than 20 days of sketching began, and I began to look forward to the next life in a foreign land, eager to know more about such a beautiful and elegant ancient town.
In fact, Hongcun was originally called Hongcun. According to Wang's genealogy, it was called Hongcun at that time because it was "enlarged into Taiyi elephant", and it was even more Hongcun during the reign of Qing Qianlong, which meant wide development and prosperity. Hongcun is located in the northeast of yi county, with a village area of 19. 1 1 hectare. Hongcun was built in Shao Xi period (A.D. 1 13 1) in Nanning, and it has been more than 800 years since then. Backed by Yangzhanling and Leigang Mountain. , located in the remaining veins of Huangshan Mountain, with high terrain. It's often gloomy, sometimes it's like splashing ink, sometimes it's like freehand brushwork. It is like a long scroll of mountains and rivers, integrating natural landscape and human landscape, and is known as "the country in Chinese painting".
Parked in the south lake, Hongcun has a panoramic view and is displayed in front of you. Because Hongcun is located at the southern foot of Huangshan Mountain, surrounded by mountains, the South Lake is full of clear water, sparkling, green lotus swaying, ducks splashing in the water, the reflection floating, the water is the same color as the sky, and then the distant peak near the building reflects together in this colorful lake, just like a deep, quiet, fresh and bright ink painting.
Nanhu Lake was built in the third year of Ming Dynasty (1607). From Yongle to Wanli, Hongcun built a building in Gai Lou, with a scattered population. It is not enough to store water in the moon pool. At the end of Wanli, hundreds of acres of fertile land in the south of the village were chiseled to tens of feet, surrounded by stones, imitating the wind of autumn moon in Pinghu, West Lake. The lake is in a big bow shape, and the dike is divided into two levels. The upper floor is 4 meters wide. The old trees are towering and green, the trunk is wrapped with green vines, the birds are singing, and the weeping willows are graceful, like a girl in a toilet mirror, sprinkling her hair on the lake. The green lotus on the lake is swaying, ducks are splashing in the water, and there is another scenery. The reflection of the whole lake is floating, water and sky are the same color, far from the peak and near the house, falling into the lake. In addition, the interaction between the shade and the sun, the harmony between light and shade, and the appropriate movement make it look deep, quiet, fresh and bright. In the history of Nanhu Lake, it was overhauled three times. 1986 rebuilt Zhongli, Jiaqing was built in the autumn of the fifth year of Jiaqing. After visiting South Lake, Wu Xilin wrote:
Stroll into the village and cross the narrow path. There is a pond called Yuebog in the village. The common people are also called Yuetang, which is the so-called "calf". Hongcun people believe that "when the wind blows, the air will disperse and the boundary water will stop." There is a natural water cave in the original site of Yuefen, and groundwater gushes all the year round. A pond was built in the natural water cave to store the "internal yang water", which can achieve the effect of "beautiful mountains and clear waters, and the peaks fall into the pond". So they built the pond into a half-moon shape, which means "the full moon leads to losses", hence the name "Moon Marsh". In the design of the Moon Marsh, taking the surrounding mountains as reference, the distant mountains and the near water learn from each other, and the water surface is opened very cleverly to create a square effect. Although there isn't much open space around Moon Bay, I don't think the space is cramped. Moreover, because the surrounding horsehead walls are patchy and harmonious with Moon Bay, this sluice is full of clear waves, swaying clouds and picturesque scenery.
Moon marsh is a combination of spring water and puddle. It mixes spring water and stream water in the village. After the two streams of living water meet, the pool water will flow clearly and be inexhaustible all year round. And it should meet the desire of Hongcun people to gather Feng Shui, with flowing water, pool surface like a mirror, water source landscape and multi-storey buildings complement each other; Blue sky and white clouds fall into the water, chatting with the old people, and playing with young women and naughty children, a vivid folk picture scroll is displayed in front of people. Since then, in the twists and turns of Hongcun, the water has been flowing slowly and freely, and the moon marsh has naturally played a regulatory role, which is also the wisdom of Hongcun people.
Moon Lake is green all the year round, with a mirror-like surface, bluestones spread around the pond and marsh, white walls and blue tiles arranged in an orderly manner, blue sky and white clouds falling into the water, old people chatting, women washing gauze and handkerchiefs, and urchins laughing. In fact, the moon pool has become a space for people to enjoy, an open-air stage of "customs and feelings" during the spontaneous gathering of villagers. Geese dance in the pool, ducks play in the clear waves, the air is foggy and the emblem is soft and gentle. Isn't this a beautiful painting by people in southern Anhui? So some people call it a wooden structure that walks through the old house in Hongcun and looks up at columns, beams, purlins, rafters and other components. Beam bracket, melon column, fork, sparrow, bucket, etc. Exquisite carving, exquisite design and gorgeous decoration. All kinds of wooden structure components under the eaves around the courtyard of the house are carved into various lifelike fairy figures, birds and animals, and drama stories. Smooth lines, elegant and handsome, dazzling, beautiful and amazing.
Chengzhitang, an ancient building highly praised by tourists, was built around 1855 and was the residence of Wang Dinggui, a salt merchant in the late Qing Dynasty. Brick-wood structure, the whole house has 136 wooden columns, nine patios, seven floors, 60 rooms and 60 doors, covering an area of 2 100 square meters and a construction area of 3,000 square meters. The whole house has an outer court, an inner court, a front hall, a back hall, an east wing, a west wing, a study, a fish pond hall, a kitchen and a stable. There are Paishan Pavilion playing mahjong, Yun Xuan smoking opium, bodyguard room, maid living room, Ci Tang and small study room. There are ponds and wells at home, so you don't have to take water out. The front hall is a cloister, with a three-story structure, divided into upper and lower halls, carved beams and painted buildings, tin barrels around the courtyard, and Nanhu Academy on the top. At the end of the Ming Dynasty, Hongcun people built six private schools on the north bank of Nanhu Lake, which were called "Lakeside Six Hospitals". During the Jiaqing period of the Qing Dynasty (18 14), it took four years to merge and transform the six academies into a large-scale private school, named "Wenjiashu", also known as "Nanhu Academy".
The Academy is an ancient building with a strong Huizhou architectural style, covering an area of more than ten acres, with a lake and clear water outside, an exquisite rockery inside and a century-old cypress on the field. The academy consists of Zhitong, Wenchang Pavilion, Wudao Pavilion, Huiwen Pavilion, Wanghulou and Tanyuan Garden. "Know the hall" is the place where teachers give lectures; "Wenchang Pavilion" is dedicated to Confucius for students to pay homage to; "Enlightenment Pavilion" is the place for enlightenment reading; Huiwenge is to read four books and five classics for students; "Wanghulou" is a place for leisure viewing and rest; The Garden is an inner garden. There is a lake in front of the academy, and the water is clear, and there are many floors behind it. White walls and tiles, clear water and blue sky, complement each other. The hall of the Academy is magnificent and the gatehouse is well preserved. The original gold tablet of "Taking Letters from Wen Jia" was written by Mr. Liang, a great calligrapher in Qing Dynasty and a lecturer in imperial academy, at the age of 93. On the west side, there is the "Wanghuting" with a shed roof. The window faces the South Lake, and there is a horizontal plaque with "lakes and mountains" hanging on it. You can see lakes and mountains from a distance.
History is also a place where officials and scholars give lectures. Wang was a cabinet official in Qing Dynasty, and served as ambassador to Britain and Japan during the Republic of China. Wang Daxie, acting Minister of State, studied here in his childhood.
Splendid and magnificent Chengtang, exquisite and chic ordinary houses, South Lake Moon Marsh with tender feelings in four seasons, Hongcun has been with history for nearly a thousand years, and the prosperity and elegance of Huizhou commercial gangs, which can't be concealed for hundreds of years, are still like the charm of music, still floating under today's Yangzhanling and echoing gently. However, the old man has gone, and the water has flowed from the east, leaving an old house for people to mourn the ancient time that is gone forever in the sunset glow.
Model essay on college students' research report II:
abstract
Based on the ecological footprint theory, the ecological footprint and ecological carrying capacity of Xi 20 13 years were calculated by constructing the ecological footprint model. The results show that there is a large ecological deficit in Xi, the ecological environment is in a state of over-exploitation and utilization, and the development model is unsustainable. In order to alleviate this problem, it is necessary to formulate countermeasures from the aspects of controlling population size, ensuring cultivated land and green space area, and advocating low-carbon lifestyle.

Research Report on Sustainable Development of Xi Based on Ecological Footprint Theory
First of all, the questions raised
The Shaanxi Provincial Party Committee and the provincial government have made a decision to jointly build xi 'an by provinces and cities, and put forward the grand goal of building Xi 'an into an international metropolis with open and inclusive, high-end industries, complete functions, livable tourism and distinctive historical and cultural characteristics as soon as possible. The 12th Party Congress of Shaanxi Province also proposed that xi 'an should be built into an international metropolis with a population of100000 by 2020 to achieve a new leap in economic strength. In this context, it is not difficult to predict that more migrants will flood into Xi in the future. Whether Xi 'an's ecological carrying capacity can accept a large number of immigrants is related to the strategy of Xi 'an and whether the planning goal of Guanzhong-Tianshui Economic Zone can be truly realized. It is not difficult to predict that in the future, the ecological environment and ecological carrying capacity will become the main restrictive factors for Xi to achieve sustainable development. Therefore, how to break through the ecological bottleneck, accommodate the established population target with relatively fragile ecological carrying capacity, and realize the sustainable development of Xi is a major topic worthy of study.
Second, the research objectives
Under the guidance of the sustainable economic development strategy, the ecological footprint theory is organically combined with the urban population scale, and an ecological footprint model is constructed to calculate the ecological carrying capacity of Xi, analyze the suitable population scale of Xi, and establish the corresponding early warning mechanism for population resource evaluation, so as to provide reference for Xi's future sustainable development and theoretical basis for government decision-making. This is the research goal of this topic. Third, the research significance
1. Theoretical significance: At present, domestic scholars have studied the appropriate population size of the Production and Construction Corps of Ning, Hangzhou, Guizhou and Xinjiang by using the ecological footprint theory, but as an important provincial capital city in the west, Xi has not been used to study the appropriate population size within its ecological carrying capacity and evaluate its sustainable development ability. This topic will fill this theoretical gap to some extent.
2. Practical significance: With the development of the western region and the construction of Guanzhong-Tianshui Economic Zone, it is not difficult to predict that more immigrants will flood into Xi 'an, an important city on the Silk Road in the future. Whether Xi 'an's ecological carrying capacity can accept a large number of immigrants is related to the strategy of Xi 'an and whether the planning goal of Guanzhong-Tianshui Economic Zone can be truly realized. Under the guidance of sustainable economic development strategy, it is undoubtedly of great significance to explore the strength of its ecological carrying capacity, analyze the suitable population size of Xi and establish the corresponding evaluation and early warning mechanism. ?

1. Research principles and methods
Summary of (1) Ecological Footprint Theory
The theory of ecological footprint analysis was put forward by William, a Canadian eco-economist, in the early 1990s. It is a common method to measure the sustainable development of a region by measuring the gap between the demand of human beings for natural biophysical quantities and the biophysical quantities that nature can actually provide. Over the years, by
This theory has a scientific and perfect theoretical basis and a simplified and unified index system, which has been widely adopted by scholars at home and abroad.
The concrete application of ecological footprint theory is realized by establishing ecological footprint model. That is, the demand for natural biophysical quantities is expressed by the size of ecological footprint, and the supply of biophysical quantities is expressed by the size of ecological carrying capacity. By comparing the ecological footprint and ecological carrying capacity, we can judge whether the production and consumption activities of a country or region are within the carrying capacity of the local ecosystem. When the regional ecological carrying capacity is greater than the ecological footprint, it is called ecological surplus, then the human production and consumption activities in this region are within the ecological carrying capacity, and the ecological environment is in a state of sustainable development. On the contrary, the supply of ecological carrying capacity can not meet the demand, which is called ecological deficit. The human production and consumption activities in this region are beyond the scope of ecological carrying capacity, indicating that regional development is unsustainable in space or time.
(2) Calculation of ecological footprint index: The ecological footprint (ecological resource demand) is:
EF=N×ef=N× ∑rjAi= N ∑(ci/pi)
Where EF is the total ecological footprint (hectare) of this area; N is the population; Ef is the per capita ecological footprint (hectare/person); Rj is the equilibrium factor, and I is the consumption item type; Ai is the per capita biological production area (per capita ecological footprint) converted from Class I consumption items; Pi is the annual (world) average output (kg/ha) of class I consumer goods produced by biological production land, and ci is the per capita annual consumption of class I consumer goods. Ecological carrying capacity (supply of ecological resources) is:
EC=N× (ec)=N×aj×rj×yj
Where EC is the total ecological carrying capacity of this area (hectare); Ec is the per capita supply of ecological resources (hectare/person); N is the population; Aj is the per capita biological production area; Rj is the balance factor; Yj is the yield factor.
If ef & gtEc, there is ecological surplus, if ef
2. General situation of 2.Xi 'an
(1) natural investigation
Xi 'an, formerly known as Chang 'an, is the capital of Shaanxi Province. Guanzhong basin, located in the middle of Weihe River basin, is between east longitude 107.40 degrees and north latitude 33.42+009.49 degrees, bordering Weihe River and Loess Plateau in the north and Qinling Mountain in the south. It is about 204 kilometers long from east to west and about 1 16 kilometers wide from north to south. Including the urban area, it covers an area of 9983 square kilometers.
Area 1066 km2. The city has jurisdiction over nine municipal districts, namely Xincheng, Beilin, Lianhu, Yanta, Weiyang, Baqiao, Yanliang, Lintong and Chang 'an, and four counties, namely Zhouzhi, Lantian, Huxian and Gaoling. Xi 'an Plain belongs to warm temperate zone and semi-humid continental monsoon climate, with four distinct seasons: cold, warm, dry and wet. Winter is cold, windy, foggy and less rainy and snowy; Spring is warm, dry, windy and the climate is changeable; Summer is hot and rainy, drought is prominent, and there are many thunderstorms and strong winds; Autumn is cool, the temperature drops rapidly, and the autumn rain is obvious. The annual average temperature is 13. 0℃~ 13.Xi 'an formation is complex in development and diverse in structural types, which provides favorable conditions for the formation of various mineral resources. 47 kinds of mineral resources have been discovered, including 2 1 kind of metallic minerals, 22 kinds of nonmetallic minerals, 2 kinds of energy minerals and 2 kinds of other minerals. Most metallic and nonmetallic minerals are distributed in South Qinling Mountains.
(2) Social profile
Xi 'an is located in the center of China's land map, which is the junction of two major economic regions in central and western China, and the only way for the northwest to reach the cities of Central Plains, North China and East China. It is the bridgehead for the country to implement the strategy of developing the western region. It has an important strategic position of connecting the east with the west and connecting the north with the south. It is one of the largest node cities in the national trunk highway network. Xi has excellent infrastructure, developed traffic conditions, convenient communication and rapid economic development. By the end of 20 13, the registered population of Xi city was 8,069,300, with a per capita GDP of 56,988 yuan. 3. Calculation of ecological footprint and ecological carrying capacity in 20 13 years in 3.Xi city
Using the ecological footprint calculation model, the local ecological footprint of Xi 20 13 was calculated according to the relevant data in Xi Statistical Yearbook in 20 14, and the biological resource account and fossil energy account in the calculation of Xi 20 13 were established respectively (table 1, table 2). It should be noted that the latest data of grassland, forest land, construction land and water area are difficult to obtain, and considering that these data have not changed much in recent years, the ecological carrying capacity data adopts the statistical value of 20 1 1-2020 Xi land consolidation plan. The supply of ecological footprint reflects the ecological carrying capacity of Xi, that is, the effective supply of resources According to the recommendation in the report "Our Common Future" of the World Commission on Environment and Development (WCED), 65,438+02% of biological production land area should be set aside to protect biodiversity, so this 65,438+02% of biodiversity protection area was deducted when calculating the ecological footprint supply of Jiangsu Province.

Note: Data are taken from Xi Statistical Yearbook -20 14. ① The unit is m3/hm2；; ② The unit is cubic meters.
Table 2 Ecological Footprint of Industry and Energy Consumption in Xi2013 Years
Note: Data are taken from Xi Statistical Yearbook-2065438+04 [8]; The conversion coefficient in the calculation adopts the average calorific value of the world unit fossil energy land area [15]; ① The unit is 104m3, and the density is 0.5kg/m3；; ; ② The unit is104 kW h, and the converted standard coal coefficient is 3.27 t/104 kW h. 。
Table 3 Balance between per capita ecological footprint and ecological carrying capacity in Xi 2013 years

4. Analysis of sustainable development and ecological security in Xi 2013 years.
In 20 14 years, the per capita ecological footprint of Xi was 2.45970 hm/ person, the ecological carrying capacity was only 0.27 162 hm/ person, and the ecological deficit was 2. 18808hm/ person. The per capita ecological footprint is about 9.06 times of the per capita available ecological carrying capacity. It can be seen that Xi 'an's development model is currently in an unsustainable state, and ecological security is seriously threatened. In order to alleviate the current ecological deficit of Xi, it is necessary to take the following corresponding measures:
(1) Properly control the population size of Xi 'an and alleviate the overall ecological deficit pattern of the city.
(2) Strengthen the protection of cultivated land, strengthen the protection of existing natural forests and wildlife, promote tree planting and greening, curb soil erosion, and promote eco-agriculture in the city. Through various new technologies and management measures, the biological yield per unit land and the carrying capacity of the ecosystem will be improved.
(3) Omnidirectional
The sustainable orientation of social consumption structure, such as controlling the growth of family motorized transportation, encouraging citizens to travel green and reducing the waste of food and water resources, has reduced the ecological footprint. . References:

The Development of Model Papers on College Students' Project Research —— Model Papers on Senior High School Biology Project Research.
Topic: Practical research on hierarchical design of biological homework in ordinary senior high schools
_ _ The subject "Practical Research on Hierarchical Design of Biological Work in Ordinary Senior High Schools" declared by the teacher was approved by the leading group of _ _ City Education Science Planning, and listed as the project of _ _ City Education Science Planning, with the approval number of. Now, according to the requirements of the notice document of the municipal education science planning office and the county teaching and research section on this topic, the research scheme and implementation plan of this topic are put forward, and the research work is ready to be formally carried out. Please leaders and experts to give consideration and guidance.
First, the background and purpose of the study.
(A) Research background
1. Analysis of school situation and learning situation
According to the batch situation of high schools in our county and the actual situation of students, our school should be well-deserved as an ordinary high school among ordinary high schools. Students who are inconspicuous or even dismissive in other schools may be regarded as treasures in our school.
Our students' general foundation is relatively weak, their study habits need to be cultivated, their learning methods are not scientific enough, and their learning ability still has a lot of room for development. There are widespread phenomena such as poor sense of achievement in learning, weak sense of self-efficacy, and lack of help-seeking consciousness in learning.
Faced with this situation, the school has also carried out in-depth thinking and taken necessary measures. For example, during the military training of freshmen in senior high school, the teaching materials are distributed to students, so that students can double it in advance. Organize teachers of related disciplines to enter the classroom, introduce students to the situation of subject learning, inspire students' morale, stimulate students' thirst for knowledge and mobilize students' enthusiasm for learning. We regard September as the psychological adjustment month for freshmen. The school organizes a series of activities to welcome new students, help them make psychological adjustment, make them adapt to the new environment, new classmates and new teachers as soon as possible, and do a good job of changing learning methods and improving learning methods. We have always stressed that now everyone is on the same starting line. As long as we insist on doing what the teacher says, our study will certainly go to a new level. As the saying goes, "what can be done today is not finished today", and the questions learned today are finished today. Don't let the learning problems accumulate indefinitely.
"It's easier said than done." All the ideas are beautiful, but the results are realistic.
It's not a day's work to cultivate study habits and change study methods. With more and more learning tasks, there are more and more difficulties and setbacks in learning, which constantly suppress the morale of students. In addition, they can't attribute it correctly, and some students even think that they are not the material, so they fall behind in their studies. But it was a terrible fall. When I regret it, I don't know how hard it will take to catch up.
This negative emotion will continue to spread, spread, infect students around, and even infect teachers. After a long time, some teachers grind them for students, lose their temper and have no fighting spirit. Some old teachers, based on their own experience, concluded that the student was hopeless and left him alone. As we know, in psychology, there is a phenomenon called "Pimarion effect", that is, teachers' expectations are transmitted to students explicitly or implicitly, which will make students shape their behavior in the direction of teachers' expectations. In this way, students themselves will be more self-destructive, and in the long run, they will fall into a vicious circle, which will seriously affect the sustained and effective development of teaching work.
2. Analysis of business situation
For a long time, the school has carried out many large-scale post training activities in combination with the county bureau, often paying close attention to the routine management of teaching and strengthening the inspection and implementation of all teaching links, with remarkable results, and the idea of striving for an efficient classroom is unshakable.
However, there is a problem that has not been well solved, that is, the homework or exercises we assign to students have always been synchronous homework based on unified sorting. After years of use, we all agree that it is not suitable for students in our school and it is very difficult. The teacher's explanation is also not targeted, and it is easy to pass. Those relatively difficult questions are repeated, and those "good students" in our minds are hardly understood. Most students are just listening to gobbledygook. The final effect of such classroom teaching can be imagined.
We know the importance of practice, which is an indispensable part of the five links in the teaching process, especially for scientific learning. Practice is not only an effective way to form skills, but also an important way to train students' thinking.
We used to encourage students to go to the bookstore to buy some exercises themselves. Although there are abundant counseling materials on the market, there are really few suitable for our students. Some students bought one, but seldom read it.
In short, the teaching work in ordinary high schools is heavy, and students' extracurricular time is occupied by a lot of homework. And many of them are mechanically repetitive tasks. As a result, students are tired of learning and afraid of doing and listening, homework plagiarism becomes the norm, and their academic performance is low, which seriously suppresses their enthusiasm for learning. What's more, it can be said that it destroys the physical and mental health of students. Some students lack self-confidence and enterprising spirit in a nervous and depressed psychological state, and gradually, they can't stand it and drop out of school. Those who insist on sitting, some have to be at the bottom of the county's second-year academic level exam. Every year, some students fail to meet the academic standards smoothly.
(ii) Purpose and significance
This topic is closely related to the actual situation of schools, teachers and students, and carries out practical research around the real teaching problems encountered, following the principles of school-oriented, people-oriented and teacher-student development, insisting on seeking truth and being pragmatic, starting from small things and seriously studying and solving specific practical problems.
Teachers take the initiative to reflect in practice, starting from the local, starting from the current, studying practical problems and putting forward topics. Learn in confusion, cooperate in confusion, carry out research, integrate theory with practice, and solve specific practical problems.
1. Through the design and research of homework stratification, teachers should increase the weight of homework preparation in the process of preparing lessons, so as to promote teachers to prepare lessons and attend classes effectively.
2. Change the assignment from focusing on the quantity and frequency of correction to focusing on the purpose and quality of assignment, so that students can effectively and timely consolidate their knowledge. Through the hierarchical design of homework, students can choose what they can eat and what they like to eat according to their own situation, thus promoting students' effective study.
3. Through the practical study of homework stratification, the effectiveness of teachers' education and teaching can be promoted and teachers' enthusiasm for work can be mobilized.
4. The organic combination of research and teaching practice will weaken students' fear of learning difficulties, enhance their initiative in learning, and improve their academic performance, which will ultimately be reflected in the academic examination results.
Through the practice and research of hierarchical homework design, students of different levels are given different levels and different forms of homework, and their individual differences are fully respected, so as to fully meet their individual needs, thus improving students' effective participation in learning, and further promoting students with learning difficulties to successfully meet academic standards, but at the same time, it will not dampen the enthusiasm of top students.
