Model essay on ecological environment investigation report

Ecological environment model report 1:

In the next semester of 20 14, we studied the course "Introduction to Socialism with Chinese characteristics's Theoretical System" under the guidance of our teacher. This course is a science to study contemporary socialism, mainly Socialism with Chinese characteristics's basic theory, development path and laws. Theoretical knowledge involving Marxist philosophy, political economy, scientific socialism and other basic theoretical disciplines is the most instructive and practical course. In the process of studying this course, there is a practical teaching link to investigate the ecological environment of Dianchi Lake in Kunming. The Party's report points out: We should put the construction of ecological civilization in a prominent position, integrate it into all aspects and the whole process of economic construction, political construction, cultural construction and social construction, and strive to build a beautiful China and realize the sustainable development of the Chinese nation.

I. Introduction to Dianchi Lake

Dianchi Lake is the largest freshwater lake in Yunnan Province, about 20 kilometers away from Kunming, the sixth largest freshwater lake in China, and it is a bright pearl on the plateau. Located in the southwest of Kunming City, Yunnan Province, it was called Nanze in ancient times, also known as Kunming Lake. Dianchi Lake is a lake with earthquake fault subsidence, which is shaped like a crescent moon. The elevation of the lake is 1886 meters, 39 kilometers from north to south and 13 kilometers from east to west. The length of lakeshore line is 163.2km, the area is 306.3km2, and the water capacity is157 billion cubic meters, so it is known as "Dianchi Lake in 500 miles". The main rivers are Panlong River, Jinzhi River, Baoxiang River, Haiyuan River, Mario River, Luolong River and Diaoyu River. The exit is mantis. Dianchi Lake water flows from Haikou to Pudu River and into Jinsha River. It is a long water system with a drainage area of 2855 kilometers. There are Jinma Mountain in the east, Bijia Mountain in the west, Snake Mountain in the north and Heshan Mountain in Dianchi Lake in the south. These rolling mountains form the natural barrier of Kunming bazi. The lake flows out of the southwest estuary and is named Tanglangchuan, which is the source of Pudu River, a tributary of Jinsha River. In the past, floods often occurred around this lake. As early as 1262, the songhua dam was built on Panlong, and 1268 dug Haikou River and added Dianchi Lake.

Discharge and reduce the flood disaster around the lake. Dianchi Lake is located at the foot of Xishan Mountain in the south of Kunming, with its northern end adjacent to Kunming Daguan Park and its southern end in Jinning County. Historically, Dianchi Lake has always been a resort for summer vacation, ranking first among Yunnan's major tourist provinces. More than 20 rivers, such as Panlong, flow into Dianchi Lake, the west of Dianchi Lake empties into the sea, and the Pudu River flows into Jinsha. In addition, there are many scenic spots around Dianchi Lake, facing Xishan Forest Park, lakeside park, Longmen Village, Guanyin Mountain, Baiyukou Lake and Daguan Park on the ridge across the water. Yunnan ethnic village, ethnic sports training base and Yunnan ethnic museum are both related and relatively independent, relying on each other, which is an ideal place for sightseeing, entertainment and vacation.

Second, the status quo of Dianchi Lake "misses the beauty of Dianchi Lake in the past", "natural and unrestrained green, beautiful spring, layers of forests are dyed. There are many kinds of feelings, and there is a kind of jade summer spirit. The blue waves are thousands of miles away, and the small waves turn into old news. I feel distressed and haggard today, and I hope Dayu will appear again. In the future, Wan Li will be sprinkled in the spring, and Dongfeng will dye three thousand miles. " As can be seen from the above, Dianchi Lake at this time is not the Dianchi Lake at that time. It's really hard to look back. In recent 20 years, with the development of economy and the expansion of city scale, the ecological environment pressure in the basin has increased and the water body has been polluted, which has led to serious eutrophication of lakes. Dianchi Lake is facing the double dilemma of water pollution and water shortage. According to the online introduction, in the second quarter of 2008, the water quality of Caohai Lake in Dianchi Lake was generally worse than that of Grade V water, and the comprehensive trophic state index was 79.4, which was a severe eutrophication state. Among the main monitoring indicators, ammonia nitrogen, total nitrogen and total phosphorus exceed the water standard of Class V, permanganate index and five-day biochemical oxygen demand reach the water standard of Class V, and the rest indicators meet or exceed the water standard of Class III. In the second quarter of 2008, the water quality in the coastal waters of Dianchi Lake was generally worse than that of Class V water, and the comprehensive nutritional status index was 64. 4, in a state of moderate eutrophication. Among the main monitoring indicators, the total nitrogen exceeds the water standard of Class V, the total phosphorus reaches the water standard of Class V, and the permanganate index reaches Class IV.

Water standard, other indicators are in line with or better than Class III water standard. 20 1 1 In the third quarter, the water quality of Caohai Lake in Dianchi Lake was generally worse than Grade V, and the total nitrogen and total phosphorus in the main monitoring indicators exceeded the Grade V water standard. The comprehensive nutritional status index is 70. 1. 20 1 1 In the third quarter, the water quality of Dianchi Lake was generally worse than Grade V, and the total nitrogen in the main monitoring indicators exceeded the Grade V water standard. The comprehensive nutritional status index is 70.3. The pollution in Dianchi Lake has gone through a long and complicated process. It is developing rapidly. Some water bodies in the outer lake have been polluted by organic matter, but the toxic and harmful pollution (mainly heavy metal pollution) is still not prominent. A large amount of nitrogen, phosphorus and arsenic were deposited at the bottom of the lake, which caused serious sediment pollution. Water pollution began in the late 1970s and entered the 1980s, especially in the 1990s, where eutrophication became increasingly serious. The causes of water pollution in Dianchi Lake are as follows: First, Dianchi Lake is located in the lower reaches of Kunming City, which is the lowest depression in Dianchi Lake Basin; Second, domestic sewage enters Dianchi Lake; Third, industrial wastewater enters Dianchi Lake; Fourth, agricultural non-point source pollution; Fifth, the rapid development of urbanization in Dianchi Lake Basin; Sixth, Dianchi Lake is a semi-closed lake, and there is not enough clear water to replace the lake. Seventh, in the process of natural evolution, the lake surface shrinks, the lake basin becomes shallow, enters the aging stage, and endogenous pollutants accumulate.

Dianchi Lake is an eutrophic lake, and some lakes show signs of abnormal nutrition, and the water color is dark yellow-green. The polluted Dianchi Lake is seriously polluted by organic matter and harmful organic matter, and the polluted Dianchi Lake is developing rapidly. Some water bodies in the outer lake have been polluted by organic matter, and toxic and harmful pollution (mainly heavy metal pollution) is not prominent. Nitrogen, phosphorus, heavy metals and arsenic are deposited at the bottom of the lake, causing serious sediment pollution. Dianchi Lake has been in the state of "aging" lake for nearly a hundred years. The annual average water temperature is 65438 06℃; The results of no survey in 1980s showed that with the change of ecological environment in Dianchi Lake, the ecological environment of fish spawning and hatching sites was destroyed, and the influence of overfishing and the interaction between fish populations, the fish population in Dianchi Lake changed greatly, leaving only four indigenous species, which were on the verge of extinction.

Golden thread fish is as tender and delicious as meat, and now it is extinct. At present, the water in Dianchi Lake has been seriously polluted, and the water body is green, which is like green paint. In Haigeng Park, standing on the edge of Dianchi Lake, there will be fishy smell coming, which is very polluted.

Third, the causes of pollution in Dianchi Lake

(1) Natural causes

Dianchi Lake is located in the lower reaches of Kunming, which is the lowest concave zone in Dianchi Lake Basin. In addition, Dianchi Lake has a long evolutionary history of about 3.4 million years. In the process of modern evolution, the water surface has shrunk, the lake basin has become shallow, and it has entered an aging stage, and endogenous pollutants have accumulated, resulting in serious pollution. At present, the water area of Dianchi Lake is only 25% of that of ancient Dianchi Lake, and its water storage capacity is only 25% of that of ancient Dianchi Lake.

1.9%。 Dianchi Lake has evolved into a semi-closed lake with an average annual outflow of

1.49? _? 108m3, accounting for only 1 1% of its capacity. Due to the long cycle of lake water replacement, slow lake flow, poor material circulation, unbalanced access, limited self-purification function and a large number of pollutants precipitation, a large number of internal pollution sources are formed.

(B) Human factors

First, domestic sewage enters Dianchi Lake; Second, industrial wastewater enters Dianchi Lake; Third, agricultural pollution sources; Fourth, the rapid development of urbanization in Dianchi Lake Basin; Fifth, Dianchi Lake is a semi-closed lake, and there is not enough clear water to replace the lake. In the past, Kunming was limited by the size of the city, industrial production, population and living standards, and the pollution load discharged did not exceed the self-purification capacity of Dianchi Lake, which enabled Dianchi Lake to maintain ecological balance. With the rapid increase of production and domestic water consumption, the pollution load of industrial wastewater and domestic sewage discharged by cities has greatly increased, and this ecological balance relationship has been seriously damaged, resulting in serious pollution and deterioration of the water quality in Dianchi Lake.

Root cause. For example, in 2005, the amount of sewage discharged into Dianchi Lake was as high as 230 million tons, and the main pollutants were: total nitrogen 9750t, total phosphorus 1 160 t and CODcr 30674 t, among which domestic pollution sources accounted for about 45% ~ 58%, and industrial pollution sources accounted for about1%~. When the sewage discharged into Dianchi Lake reached 2 10/00000 tons in 2007, the total nitrogen was 8 155t and the total phosphorus was 8 155t.

1087 t. However, under normal CODcr, the water environmental capacity of Dianchi Lake is only 4000t, 400t and 1 1000t respectively. With such a high pollutant discharge, all the water quality indexes of Dianchi Lake are inferior to the national V-class surface water quality standard, and more than 70% of the water bodies are in a state of severe eutrophication.

Fourth, personal experience summary

Water is the source of life. The relationship between man and water is just like the relationship between fish and water. No matter when and where, it is always inseparable. Dianchi Lake in Yunnan is our mother river, which nurtures us Yunnan people, gives us a well-known spring city and gives us a warm home. She has done too much for Yunnan. Without her, Kunming would not have such a suitable climate, Kunming would not be so prosperous, Kunming would not attract more foreign tourists, and Kunming would not become a holiday destination. However, Dianchi Lake is now facing many crises, and its water pollution has been very serious. Although faced with such difficulties, the central government and local governments have given a lot of manpower, financial resources and material resources, but it is far from enough. In order to restore the original appearance as soon as possible. As a member of the country, we have the right and obligation to do something for Dianchi Lake, and it is our bounden duty to protect the ecological environment. We only have one home, and if it is destroyed in any form, the home we live on will eventually be destroyed.

As contemporary college students, we should carry forward the spirit of the Party, arm ourselves with Socialism with Chinese characteristics Theory, establish a correct world outlook, outlook on life and values, unswervingly follow the Party's line, adhere to the road of cultural development in Socialism with Chinese characteristics, take Marxism-Leninism and Scientific Outlook on Development as the guidance, adhere to the direction of advanced socialist culture and take scientific development as the theme. Taking building a socialist core value system as the fundamental task, meeting people's spiritual and cultural needs as the starting point and the end result, and taking reform and innovation as the driving force, we will develop a national, scientific and popular socialist cultural festival facing the world, facing the world and facing the future, improve the quality of national civilization, enhance the soft power of national culture, carry forward Chinese culture, and strive to build a socialist cultural power. The Party's report points out: We should put the construction of ecological civilization in a prominent position, integrate it into all aspects and the whole process of economic construction, political construction, cultural construction and social construction, and strive to build a beautiful China and realize the sustainable development of the Chinese nation.

So, start with the little things around you and start with yourself. Everyone collects firewood with a high flame, and each person makes a small piece, which adds up to a big piece. As the saying goes, a spark can start a prairie fire. On campus, when I see garbage on the ground, I will take the initiative to pick it up and put it in the trash can. When I saw the water left by others, I fell on the flowers and plants. Washing clothes with laundry and water in the dormitory is all within my power. In the face of serious environmental threats, we should make good use of network resources, check online, see what is the most suitable decompression method, and learn more about the source of threats. Whether in school or in society, we should actively participate in the maintenance of the ecological environment, vigorously support the government's management, and actively publicize the importance of environmental protection to the grassroots.

Protecting the environment is everyone's responsibility!

Model essay on ecological environment investigation report 2:

I. Reasons for investigation:

In recent years, with the exploitation of a large number of mining industries, the discharge of polluted wastewater and the destruction of water and soil resources, people's lives have lost coordination. Because coal mine wastewater contains a lot of fluorine, people will suffer from various diseases. So, in order to get rid of the fluorine virus in my hometown, I made an investigation report in Black Soil Township of Zhijin, Guizhou.

Second, the purpose of the investigation:

In order to inherit the virtues of the Chinese nation, carry forward the spirit of "messenger of spring" and make it serve the society and feed back the hometown. With the development of science and technology in recent years, my hometown is changing with each passing day. Although it has been developed, the ecological environment has been destroyed. With the exploitation of a large number of coal mines, the interest in controlling water and soil pollution is weakened, so the fluorine content of water is high; Not only is it not conducive to the growth of crops, but it will also destroy the metabolism of human life system and endanger life safety. A large number of fluorosis, dental fluorosis, deformed children, and so on abound. So in order to feed back and serve the people, I made an analysis report to my hometown.

Third, the survey methods and results:

(1) investigation, through field investigation and interviews, we know that the local coal mines are rich in reserves and convenient in transportation. Under this favorable condition, a large number of coal mines are mined reasonably but managed irrationally, which leads to serious water pollution, unbalanced ecological soil and serious harm to crop growth and water problems in the field. Through scientific and reasonable statistics, although the development of hometown has made great progress in recent years, the prevalence rate of people is increasing. Various types of diseases are also increasing.

(2) Investigation results: Through cooperation with the village committee and on-the-spot investigation, we know that the main element endangering people's lives is fluorine, which is the product of rare gas immersed in water. Although the incidence of poisoning patients is high, and pollution sources are easy to spread, with the help of the village committee and many Hope Water Conservancy, the implementation of the new water control scheme and the preparation stage of investigation instruments have gradually formed a unity, initially forming the implementation of the scheme, and at the same time getting people's cooperation, solving many necessary problems.

Four. Survey data and principle analysis:

(1) survey data, through interviews and field surveys, it is concluded that the incidence of fluorosis is 95.5%, and other incidences caused by fluorosis are 23.53%. Few people are not disturbed by fluorine, and many of the data obtained are not very scientific because the instrument is inaccurate. The obtained data can be adjusted according to the size of the deviation, and the main contradiction can be grasped as a whole. Further study on fluorosis.

(2) According to the principle of poisoning and infringement, fluorine is a rare gas element with symbol F and atomic number 9. It is one of the halogen elements, and it is yellowish. Under normal circumstances, fluoride will seize the carbon element in the teeth, leading to yellowing of the teeth and uneven signs. Deep poisoning can also lead to physical deformity, which is not conducive to children's physical development.

Investigation and summary of verb (abbreviation of verb);

After more than a month's investigation and study, although a field questionnaire was obtained, there were many problems. The purpose of the investigation is to ensure the implementation of future plans and adjust the relationship between disposable and non-disposable.

First, there is something wrong with the investigation.

(1) Many places with fast water potential are difficult to access, so it is difficult to determine the extent of fluoride's invasion of land resources.

(2) During the investigation, there was insufficient publicity and poor communication with the villagers during the visit.

(3) When visiting or investigating, the instruments and equipment are not accurate, the investigation equipment is poor, and there is a lack of analysis of the shooting data.

(4) Short investigation period, short time and insufficient preparation. The relevant reference materials are lack of research.

(5) Lack of teamwork and communication leads to many one-sided conclusions.

(6) The influence of weather and geographical factors.

(2) Solve the problem factors in the investigation,

(1) In future related investigations, we should pay attention to fully preparing materials and doing more on-the-spot investigations to improve the investigation level.

(2) Multi-functional use of related majors to explain problems and consult research teachers.

(3) Go out to investigate in the form of a team as much as possible to improve the rationalization and standardization of the conclusions.

Rationality of intransitive verbs investigation plan and its significance in the future;

In a lot of data, try to take this scheme as the standard, try to improve the scheme, try to contact with local departments, try to get their support, and draw corresponding conclusions so as to make on-the-spot investigation and make the scheme reasonable. Strive to contribute to the people in my hometown and get rid of the suffering of the disease. I hope the village committee and local departments can build water conservancy projects to help people get rid of water pollution. This scheme is beneficial to field investigation and research. After gradual implementation, a complete and unified planning scheme can be formed.

Demonstration report on ecological environment research 3:

I. Introduction

On June 5438+February 3, 2007, the General Office of the State Council of the People's Republic of China issued the Notice of the General Office of the State Council on Restricting the Use of Plastic Shopping Bags in Production and Sales. This notice, known as the "Plastic Prohibition Order", clearly stipulates that the production, sale and use of plastic shopping bags with a thickness less than 0.025mm are prohibited nationwide from June 1 day, 2008, and supermarkets and shops are not allowed to provide free shopping bags to consumers.

The "plastic ban order" implemented by the state aims to limit and reduce the use of plastic bags. In the case of "white pollution", there are problems of large consumption and insufficient recycling of plastic products in China. If a large number of plastic products cannot be effectively recycled, it will cause serious damage to land and air. It has been seven years since the implementation of the "Plastic Prohibition Order". After the implementation of the "plastic ban", I made the following investigation on the use of plastic shopping bags.

II. Overview of related categories and current situation

(A) Problems in China's economic development

Now China's economy is developing rapidly, and the people are greatly encouraged, but we can find a big problem, that is, the pollution of local factories is quite large. In the past, the clear river turned into Heihe River, and countless plastic bags were dug up in the land ... So although the economy is developing rapidly, our living environment has been sacrificed too much, and the economic development at the expense of the environment has finally seriously damaged the sustainable development of the local economy. If a place ignores the protection of the environment in the process of economic development, natural resources are exhausted and environmental pollution is becoming more and more serious, then what can we rely on for further development after obtaining short-term economic development? Destroying the indispensable environmental foundation of local economic development at the expense of the environment is completely killing the goose to get the egg, self-destruction and undermining its own sustainable development. In recent years, western developed countries have transferred enterprises with high pollution and high energy consumption to developing countries on a large scale, and in fact, they have deeply realized the seriousness of environmental pollution. Are we going to repeat their mistakes and taste the pain they have experienced because of environmental pollution again?

Sacrificing the environment for economic development will eventually damage the local resources and environment, living environment and living environment. The economy has developed for a period of time, but at the same time, the living environment in this place is bad, air and water resources are seriously polluted, natural resources are exhausted, diseases are prevalent, people's basic survival is greatly threatened, and people even have to return to their hometown. What is the significance of the economic development of this place? Looking at the changes of Lop Nur desert in Xinjiang in the past 100 years, we find that Lop Nur has changed from a natural lake with lush aquatic plants and rich fish to an inaccessible Gobi desert today. Every step of it profoundly explains the great pain caused by the rapid population expansion and uncontrolled resource development. Lop Nur's Today is a clear proof and warning to the destruction of the natural environment on which human beings depend.

Protecting the environment can greatly promote the sustainable development of the economy. If a place has great environmental protection, beautiful natural environment, fresh air and everyone is healthy, people will live and work in a good environment every day, which in turn will provide immeasurable power for the further development of the economy. The rational and orderly development and utilization of natural resources will put an end to the phenomenon of uncontrolled waste of resources, and will also provide strong support and guarantee for the sustainable economic development of a place tomorrow.

(2) Environmental issues related to the people

Economic development cannot be at the expense of the environment. Protecting the environment is beneficial to the present and the future. We should really solve the problem of environmental pollution, protect our living environment to the maximum extent and realize sustainable development.

Speaking of sustainable development, the use of shopping bags closest to our lives is undoubtedly one of the most important issues. Every day in a city,

Tens of thousands of shopping bags are needed, and the pollution caused by time is also quite huge. We must do something. Using self-service shopping bags is a very important solution.

(3) About the city where I live: Fuling.

Fuling is a third-tier city with an urban population of nearly 500,000. There are 250 thousand garbage bags used every day, which is quite scary. After all, there are so many cities in China. Therefore, I need to investigate the current situation of shopping bags used by urban residents in order to draw some conclusions and put forward some suggestions.

Third, the survey results and reasons analysis

In order to investigate the use of shopping bags in Fuling city, I chose Lotte Mart, the largest supermarket, to count the customers' use of shopping bags at several checkout counters at some time of the day. I brought my own statistical table and wrote it on the questionnaire in real time. The picture below shows the questionnaire I used.

It can be found that among the 100 people I counted, only 1 1 people brought their own shopping bags, more than half of them bought shopping bags, 53 people did not apply for shopping bags, and 36 people who used shopping bags bought shopping bags.

Then, I believe everyone is not satisfied with this result, and the awareness of environmental protection has not reached an impressive level. There are really few people who bring their own shopping bags. So we want to know why after seven years of policy adjustment, the situation is still not optimistic. I believe this has something to do with the culture inherited by our country. Although we are patriotic, most of the time we are selfish. We think shopping bags are completely unnecessary. Although we will do a lot of public service advertisements on TV to remind everyone, we will feel troublesome and irrelevant when we are not seriously disturbed by the environment. The fact that the ecological environment is destroyed listed in news, newspapers and the internet is only a moment in our minds, but it is not numb afterwards. Why should I care about environmental protection? If I do it, others will follow suit. Is it ridiculous that I did this? Why should I bother myself? I think the problem lies not in the lack of publicity and facts, but in people's selfishness, people's psychological factors and a country's culture. This is a more in-depth problem. I think it takes time to solve the problem, and it can't be completed immediately.

Fourth, targeted countermeasures and suggestions

Therefore, a survey of people who use shopping bags in Fuling city found that the results were not satisfactory, so how should we reflect and do it? First of all, I think it is most important to improve people's quality while China's economy is developing. No matter how you promote it, people without quality will never have quality. We should do a good job in the education of basic national policies, instead of blindly increasing the publicity of environmental protection. This can be said to be mandatory, but it has not been deeply rooted in people's hearts, and people have not spontaneously realized the importance of environmental protection. Social development is always a process, and we must not rush headlong into it, otherwise it will violate the facts and the laws of nature. You make Africans pay attention to environmental protection, and people will pay attention to it even if they can't eat.

What is environmental protection? If it gets bigger, it will be bad for you. So as long as we go in the right direction and realize it, there is hope. As time goes on, we will find the result. Let nature take its course and everything will be fine.

Questionnaire survey on building an eco-friendly society

1. Do you bring your shopping bag when you go to the supermarket?
