In daily study, work and life, writing is the most unfamiliar thing for everyone. Writing can exercise our habit of being alone, calm our hearts and think about our future direction. So, how to write a composition? The following are six essays on environmental investigation reports I collected for you, which are for reference only and I hope to be helpful to you.

In environmental science, it is generally believed that the environment refers to the space around people and various natural factors that can directly affect human life and development. In the course of millions of years of human history, the environment has played a great role in creating human civilization and progress. Atmosphere, water source, land and grassland are the material basis for human survival; Forests, mineral deposits and other resources provide materials for the continuous development of mankind and create a high degree of human civilization on earth. However, while developing and utilizing environmental resources, human beings have also produced a series of environmental problems for their bottom-up living environment. To this end, I made a survey.

Investigation time:

20xx in the evening of April 15. Location: Home network. Survey object: global natural ecological environment.

Findings:

1。 The ozone layer is destroyed. The ozone layer accounts for one hundred thousand of the total stratosphere. Although the content is extremely low, it can absorb ultraviolet rays. However, due to the destruction of human beings, the ozone layer is rapidly depleted and extremely damaged. Such as the ozone hole in Antarctica. During the period of 1994, the ozone layer over Antarctica was destroyed by 24 million square kilometers. The ozone layer over Antarctica was formed 2 billion years ago, but it was destroyed by 60% in the last century. The ozone layer over Europe and North America decreased by 10%- 15% on average, and even decreased by 35% over Siberia. Therefore, scientists warn that the ozone layer above the earth is damaged more seriously than most people think.

2。 Freshwater resources crisis. Although two-thirds of the earth's surface is covered with water, 97% of it is undrinkable seawater and less than 3% is fresh water, but 2% of it is sealed in polar glaciers. Of the only 1% fresh water, 25% is industrial water, 70% is agricultural water, and only 5% can be used for drinking and other domestic purposes. At present, more than 100 countries and regions in the world are short of water, and 28 of them are listed as countries and regions with serious water shortage. According to statistics, the total area of water-deficient areas in northern China is 580,000 square kilometers, and there are more than 300 cities in China that lack water, with an annual water shortage of 5.8 billion cubic meters. Due to the destruction of human beings, the water resources of the earth are limited. The Colorado River in the United States, the Yellow River in China and many other great rivers have lost their former glory, and the magnificent sight of "entering the ocean for safety and never coming back" has become a historical memory.

3。 Land desertification. At present, the phenomenon of desertification in the world is still intensifying. More than 1 200 million people in the world are directly threatened by desertification, among which1. 3.5 billion people are in danger of losing their land in the short term. By the end of 1996, the global desertified land had reached 36 million square kilometers, accounting for 1/4 of the total land area of the earth, equivalent to the total land area of Russia, Canada, China and the United States. More than 100 countries in the world love the influence of desertification, which is expanding at a rate of 50,000-70,000 square kilometers per year, equivalent to the area of Ireland. For people threatened by desertification, desertification means that they will lose the most basic survival foundation-the disappearance of fertile land.

Postscript:

People will face many crises. If human beings continue to destroy the environment, then human beings will be extinct and the earth will become a distant history in the universe.

The teacher left an assignment to investigate the environment today. After school, I discussed with my classmates and decided to investigate together, so we launched the "action" of environmental investigation.

Let's investigate the air first. We searched the street. A classmate is sharp-eyed and points to the east. We looked in the direction he pointed. Wow, we almost turned our backs in surprise. When we watch it, there are cigarettes, red, yellow and white. They are like broken paint bottles in the sky. Smoke covered the sky, and the whole sky was gray. A classmate said, "My parents work in Taigang. Taigang emits a lot of smoke every day, which pollutes the air very seriously, just like the sky now. " Hearing this, we quickly fled from the grey king.

Second, investigate rivers. So we went to Yinma River, where we saw clear rivers and small fish. There is only a black river in front of me. An uncle saw us puzzled and said, "Alas, the river water pollution is too serious now." Small fish are dead, flowers and grass are withered. Now the Yinmahe River has no original style. "

God, the air is polluted, and so are the rivers. What will the future world look like?

Do you know why in the same class, some people are famous for their excellent grades, some people are left out in the cold all the year round, and some people are even hated for nothing? Ha, let me tell you something: this is caused by the learning environment.

Sleepy people in the front row and "cold windows"-50%

Wow! I can't believe that the most unfavorable learning environment is the front row and the window position (hence the name "cold window"). It may be because the teacher's lecture is too boring for middle and lower class students to understand the teacher's profound insights, so they gradually fall into a dream and get a campus jingle of "Listen to the teacher and sleep soundly". There is nothing to learn, and the conclusion is-in this learning environment for a long time, the results are not bad.

"Liangshan hero" is in the middle-36%

The teacher intentionally or unintentionally gave those intermediate positions to the so-called monitor, group leader and class representative. These people are the key training targets of teachers, otherwise how can we hand over the best learning environment? In this way, the seats in our class are seriously out of balance. Why can tall people sit in the middle, but middle-aged students who are not tall or short are squeezed into the back row? I don't know why, since I sat in the middle, not only my grades have improved a lot, but also my interest in learning has become stronger. This may be the legendary "environment makes achievements".

But after all, not everyone has such an opportunity to be "loved" by teachers, so only twenty people can become "Liangshan heroes". It's really unfair to think about the head teacher. What about the short man in the back? It is said that this seat was not made by the old class, but was consulted by the public. It seems that only 20 of the 57 people in the class have expressed their opinions, which can't be called "public opinion" ... Well, the situation of "Liangshan hero" in the middle is here, otherwise readers will think I am sorry.

Picking up girls in the back row-14%

It's not that I intentionally destroy the "heroes" in the back row, but that they are too like "kimchi". Isn't it? I remember one time when I came to the stage as a "little teacher", I suddenly found that there were top students in the middle besides the sleepy sleeper and the "cold window" in the front row, and the gangsters in the back row had long since disappeared. Instead of playing truant, I was doing something bad: chatting in private. How do I know? Just because I have natural ears, I can recognize every voice in my class.

Haha, I caught you, and you are miserable. If I am a class cadre, how can I ignore it? I walked slowly over and suddenly saw a spy looking around with a guilty face, afraid of being caught by me. Ha, how can you pickle gangsters compete with me? When I said "what are you doing", I scared them, punk. You can't blame me. If you want to complain, you can only complain that there is no good learning environment to distract you and you can't study hard. You see, how much the learning environment has to do with classroom efficiency and grades!

Finally, the percentage after the subtitle is absolutely true after my investigation. If anyone is interested, let's also investigate the students' learning environment.

Since last year, Changde has started a huge project of benefiting the people-"three reforms and four modernizations". The "three reforms" are the transformation and upgrading of direction, water and houses. It is necessary to fully implement the "white to black" project for urban primary and secondary roads, small streets and sidewalks, so that ordinary people can travel more conveniently and comfortably; It is necessary to plan and reform the hedge willow water system; Do a good job in the transformation of urban villages and shanty towns. "Four modernizations" refers to beautification, lighting, greening and digitalization. Beautifying means rectifying advertisements, completing the scientific and technological design of urban homes and signs, and embodying urban culture and urban characteristics; Lighting is not to be bright as day, but to make the city quiet at night, like a hazy poem; Greening is to increase the diversity and hierarchy of plants, improve the coverage of greening, and make the air in the city fresher; Digitalization means the improvement of scientific management and management level. Deshan was the first to be reformed. Deshan is an economic and technological development zone and a provincial-level key development zone directly managed by Changde City, Hunan Province. Located in the southeast of the city, south bank of Yuanjiang River. The jurisdiction covers an area of 54 square kilometers and the permanent population is about 65438+ 10,000. There are 54 enterprises above designated size, such as textile, machinery, medicine, paper making, food, etc., among which 1 1 family has invested over 100 million yuan, and 23 enterprises have invested over 10 million yuan.

My home is in Deshan, and I have lived here since I was a child. I heard and witnessed the changes in Deshan. Especially in recent years, the bustling Lianchi Road intersection in Deshan has been transformed and the road has become much more spacious. A Jinhua Commercial Plaza has been built in the north of Lianchi Road, which is very small and a real estate. Because the shops around the square are rented out for decoration, there are many carts and snacks and night market barbecues gathered in the square every night, and people come and go every day, which is very lively. I didn't find it at first, maybe it was a long time later. It was found that the floor tiles that were not paved in the first half of the square were full of oil stains, chewing gum and other rubbish. Although sanitation workers clean every day, some garbage sanitation workers can't completely remove those dark oil stains. This made me suddenly sigh: this is how the gap is generated! Those developed countries not only have good institutions, but also good citizens, unlike us. Some countries also care about their own environment, and the air is good.

Through observation, I think the environmental problems in Deshan mainly include the following aspects:

1. Urban management is too loose. Every night, except Jinhua Square, there are street snacks in most places in Deshan. Barbecues cause too much rubbish in the street every day.

Businessmen only care about their own interests, regardless of the surrounding living environment. As long as tables and chairs can be set on the street, it has become a place where merchants greet guests.

3. The citizens' personal quality is not high, so there is not only garbage in the night market at night. Littering and spitting can be seen everywhere during the day.

4. Because Deshan is the entrance and exit of the expressway, there are more vehicles passing through the intersection of Deshan every day, and the amount of automobile exhaust is large, which affects the air quality.

It is said that Deshan Development Zone will invest 6.5438+0.3 million yuan to build a sewage treatment plant with a daily sewage treatment capacity of 654.38+000 cubic meters. After the project is completed, it will mainly treat industrial sewage, domestic sewage and surrounding water pollution in Deshan Development Zone. Changde Municipal Party Committee and Municipal Government plan to build a new sewage treatment plant in Deshan Economic and Technological Development Zone to solve the problem of water pollution in the development zone.

At present, Changde has become the largest energy base in Hunan. The average price of industrial electricity is 0. 47 yuan/degree, key industries 0. 4 1 yuan/kwh, and the low-valley electricity price is 0. 17 yuan/degree. With the passage of time, more and more industrial projects will be settled in Deshan Economic and Technological Development Zone, and the sewage treatment capacity will also increase. At present, the sewage treatment plant has been included in the planning, and feasible measures are being formulated.

In recent years, with the rapid development of regional economy, environmental problems have become more and more serious. Preventing environmental pollution, protecting the environment and maintaining ecological balance have become important measures for social development and the obligation of every citizen. Deshan is becoming prosperous. In order to maintain the sustainable development of Deshan, I think we should take corresponding measures to improve our environment. For example:

1. Strengthen environmental education, publicize more, and let citizens know more about the environmental problems around them and their hazards. Formulate laws to protect the environment and establish organizations to protect the environment.

2. Strengthen the discussion of environmental education, enrich the knowledge of environmental protection, strengthen the popularization scope of environmental education, actively publicize the concept of environmental protection in families, schools and society, and let people participate in environmental protection through caring and caring for the environment.

3. Classified garbage recovery, reducing the construction of landfill and incinerator. For any construction or development, we must first understand whether the development will cause pollution or damage to the environment.

The government should strictly enforce the law, the people should truly abide by the law and actively report illegal incidents, and make laws to protect the environment.

Deshan is beautiful! There is Changde No.2 Middle School, and there is an old pier near Yuanjiang River where you can see the first and second bridges. Deshan is also the birthplace of German culture, which has been called "Changde Deshan has virtue" since ancient times. Deshan is also rich in tourism resources. Such as Gan Ming Temple, Gu Feng Pagoda, Gu Feng Park and Forest Park. In recent years, the Deshan Cultural Corridor has reappeared. Changde is an excellent national tourist city, and Deshan tourism resources are an important part of it. Every year on February 16, June 19 and September 19, pilgrims come to Gan Ming Temple in an endless stream. The bright butte tower every night has become a symbol of Changde. These tourism resources enrich people's amateur cultural life, and also promote the development of Deshan and even Changde Economic Zone and cultural undertakings. It is no exaggeration to say that they have become an important part of people's lives.

It is everyone's responsibility to protect the environment, and the environment and human beings exist, develop and protect simultaneously; Carry out environmental education and publicize environmental information; Produce green products and save the earth's resources; Fully participate in improving and sustainable environmental protection communities; Implement environmental responsibilities and improve the environmental protection system; Promote environmental protection and waste reduction activities and do a good job in waste management.

Deshan is our home. We should protect our homeland, care for the environment and leave more comfortable blue sky and white clouds for future generations!

Shaoxing is called "Venice of the East", so is the water in Shaoxing really good? That's not true. After investigation, it is found that the water pollution in Shaoxing is also very serious.

Take the ring river as an example. Although it is beautiful now, I used to be afraid to get close to people. Until the beginning of 1999, we seized the favorable opportunity of urban flood control project construction, and the Shaoxing Municipal Party Committee and Municipal Government made a decision to implement the comprehensive improvement of urban rivers, and put forward the idea of "giving full play to the power of society to govern the Gudu River". With a cost of 65.438+0.2 billion yuan and 270 days of construction, the ring river has finally become another beautiful landscape in Shaoxing.

How is water pollution produced? Mainly because of the older generation, or some citizens with lower quality. In the past, the river was clear, and old people often liked to wash rice, vegetables and even clothes in the river. Because it saves water and is convenient, it is normal for everyone to do whatever they want. In the long run, how can the river not be dirty? More importantly, water pollution not only pollutes the environment, but also affects people's health. Because people in some places are still drinking the water from that river, which has been used, and people's health is seriously damaged by drinking it.

So, how to solve the water pollution problem? It is important to change people, but it is more important to change the existing water pollution. It has become a reality that Shaoxing Sewage Treatment Plant connects all links of "reservoir-water plant-water supply-drainage-sewage treatment" into an industrial chain. But does this fundamentally solve the water pollution problem? I don't think so. Water is still being destroyed and pollution continues. It's still about the people. Only the people themselves realize the seriousness of the consequences of water pollution and know that water resources can no longer be destroyed and should be protected. At that time, there was no need for remediation, and water pollution would naturally disappear.

Let's take action, and I will try to eradicate water pollution!

There is a Heyang Square near my home. Heyang Square is a beautiful square, especially in spring. The grass in the square poked out its little green head, the willows stuck out its long green hair, and the flowers showed their beautiful and delicate faces ... really beautiful!

When I visited Heyang Square this afternoon, I found that Heyang Square in this spring has become less beautiful than before. What happened? Oh! It turns out that there is too much garbage in the square, which has seriously damaged the environment of the square. Who ruined this? Why do they litter and destroy the environment? They ..... With these questions, I began to investigate and analyze the causes of environmental deterioration in Heyang Square.

Investigation and analysis

I first observed the behavior of pedestrians on both sides of Yong Road in the square for a while and found that many young people and children were eating snacks. I also threw snacks on the ground while walking, and the finished food packaging bags were also thrown everywhere. There are also some adults who love smoking, throw cigarette butts everywhere after smoking and often spit everywhere. When there is wind, the wind will also blow the garbage from other places here and hide it in trees and flowers. Others brought pets into the square, and those pets urinated everywhere in the square.

conclusion

The reasons for the environmental deterioration of Heyang Square are:

1. Children and young people eat snacks at the same time, and snack bags are littered everywhere after eating. These snacks and food bags that fell to the ground destroyed the environment of the square.

2, adults love to smoke, cigarette butts are littered, and the smell of smoke is also uncomfortable. Smoke is still flying all over the sky, destroying the air in the square.

3. Some people also like spitting, and the germs in the sputum will make people who inhale the virus sick.

When the wind is strong, the wind will blow some rubbish into the flowers. People who come and go don't even want to pick it up and throw it in the trash. This will make the flowers ugly and pollute the small flowers.

Some people bring their pets into the square, and those pets defecate on the lawn of the square. Let the lawn that originally exudes fragrance become stinky.

A large number of uncivilized behaviors make the square environment worse. This has something to do with each of us.

suggestion

1. Put up several warning signs in the square that forbid damaging the environment.

Send some security guards to the square to see who destroyed the square environment. The saboteur will be fined.

Arrange several cleaners to clean the square to make it more beautiful.
