环境问题的作文英语汇编20篇

Once man did not have to think about the protection of his environment.There were few people on the earth, and natural resources seemed to be unlimited.

Today things are different.The world has become too crowded.We are using up our natural resources,and polluting our environment with dangerous chemicals.If we continue to do this, human life on earth will not survive.

We realize that if too many fish are taken from the sea, there will soon be none left.Yet,with modern fishing methods, more and more fish are caught.We know that if too many trees are cut down, forests will disappear.Yet, we continue to use powerful machines to cut down more and more trees.We see that if rivers are polluted with waste products, we will die.Yet, waste products are still put into rivers.

We know that if the population continues to rise at the present rate, in a few years, there wont be enough food.What can we do to solve these problems?

If we eat more vegetables and less meat, there will be more food available.Land for crops feeds five times more people than land where animals are kept.

Our natural resources will last longer if we learn to recycie them.

The world population will not rise so quickly if people use modern methods of birth control.

Finally, if we educate people to think about the problems we shall have a better and cleaner planet in the future.

environment

Harmony with the environment is that we live in on Earth, who is a natural son, and not only to natural persons as the conqueror, as we all know, there is only one earth and the mountains on Earth, the animals.

Therefore, the environment must be linked with social ethics, character education and practice acts as an important elent of it. Everyone must fulfil its responsibilities and obligations to protect the environment.

保护环境善待地球

众所周知，我们只有一个地球。地球是我们的家园。我无法想象，如果地球消失了，人类该怎样生存。

我们的生活不能离开地球，所以，请善待地球。

现在的空气不是很新鲜，天也不是那样湛蓝。这是为什么？因为有很多人乱砍滥伐，还污染河流。我们在森林里看不见小动物玩耍，也看不见小鱼在水里游泳。

如果长时间都是这个景象，世界末日就会来临。

那么，我们怎样才能保护环境呢？让我来给大家一些建议吧。

首先，我们可以植树。树木可以给予我们新鲜的空气，还可以吸收二氧化碳。

其次，我们可以坐公交去上学或上班,少开车。汽车排放的尾气会污染空气，它对我们的身体没有好处，对地球也没有好处。

这就是我的建议。

今天是世界环境日，让我们一起保护环境，善待地球吧！

[高中保护环境的英语小作文

The cartoon vividly reveals the phenomenon of air pollution or the decline of air quality. What exactly contribute to this phenomenon? Possible reasons can be listed as follows: firstly, vehicle exhaust gases could be one of the most leading causes. With the improvement of economy and peoples living standard, urban inhabitants in mounting numbers own their private cars. More automobiles will inevitably generate more exhaust gases. Additionally, household appliances widely used in cities also release a great mount of carbon dioxide gases, which further intensifies air pollution. Last but not least, many factories around the cities emit large quantities of untreated poisonous gases, which should also be responsible for the decline of air quality.

Definitely, air pollution will exert a detrimental impact on many aspects of peoples life. For example, many diseases such as cough, skin problem and lang cancer are caused by it. Perhaps it is high time that we should adopt some measures to solve the problem of air pollution.

参考译文：

此图生动地揭示了空气污染和空气质量下降的现象。到底是什么导致了这个现象?可能的理由罗列如下：首先，机动车的尾气排放是最主要的原因之一。随着经济的发展和人们生活水平的提高，越来越多的城市居民都拥有了自己的汽车，而更多地汽车势必带来大量的尾气排放。其次，城市里广泛使用的家用电器排放了大量的二氧化碳，这也进一步加剧了空气污染。最后，城市周边的很多的工厂，也每天向空气中排放大量的未经处理的有毒气体,这也导致了空气质量的下降。

[以环境与资源话题英语作文及参考译文

Scientists are finding ways to stop air pollution especially in big industrial areas and densely-populated cities. They are studying new ways of generating electricity that may be less damaging to the environment. In the meantime, many power plants are being modernized to give off less polluted material. Also, engineers try to design and locate new power plants to do minimum damage to the environment.

However, it may be that we still have a long way to go before we have a clean world. Nearly all of the countries are trying hard to prevent and control air pollution. There indeed seems to be no end to tasks that environmentalists will be required to do. People will continually find new ways to control pollution

我生在北京城里。小时候，我爬到院里的高楼顶上四下眺望，经常能看到颐和园的佛香阁。几年前，我住在北大畅春园，离颐和园只有数里之遥，从窗户里看佛香阁，十次倒有八次看不见。北京的空气老是迷迷糊糊的，有点迷眼，又有点呛嗓子，我小时候不是这样。在北京城里住，几乎每天都要换衬衣，在国外时，一件衬衣可以穿好几天。世界上有很多以污染闻名的城市：米兰、洛杉矶、伦敦等等，我都去过。就我所见，北京城的情况在这些城市里也是坏的。

但我对北京的环境改善充满了信心。因为这是一座现代大都市，有能力很快改善环境，北京是首都，自然会首先得到改善。不信你到欧美的大城市看看，就会发现有些旧石头房子像瓦窑里面一样黑，而新的石头房子则像雪一样白。问当地人，他们会说：老房子的黑是煤烟熏的。现在没有煤烟，石头墙就不会变黑了。现代大城市有办法解决环境问题有财力，也有技术。到了非解决不可时，自然就会解决。

我现在住的地方在城乡结合部，出门不远，就是乡政府的地面。我家楼下是个农贸市场，成天来往着些砰砰乱响的东西：手扶拖拉机、小四轮、农用汽车等等。这些交通工具有一个共同点：全装着吼声震天、黑烟滚滚的柴油机。因为有这种机器，我认为城市近郊、小城镇等地环境问题更严重。人家总说城市里噪音严重，但你若到郊区的公路边坐上一天，回来大概已经半聋了。

说到环境问题，好多人以为这是近代机器文明造成的，其实大谬不然。说到底，环境问题是人的问题。煤烟、柴油机是糟糕，但也是人愿意忍受它。到了不愿忍受时，自然会想出办法来。知识分子悲天悯人的哀号解决不了环境问题。只要知道一件事就可以解决环境问题：人不能只管糟蹋不管收拾。收拾一下环境就好了，在其中生活也能像个体面人。

当前，威胁人类生存的十大环境问题是：

(一)全球气候变暖

由于人口的增加和人类生产活动的规模越来越大，向大气释放的二氧化碳(CO2)、甲烷(CH4)、一氧化二氮(N2O)、氯氟碳化合物(CFC)、四氯化碳(CCl4)、一氧化碳(CO)等温室气体不断增加，导致大气的组成发生变化。大气质量受到影响，气候有逐渐变暖的趋势。由于全球气候变暖，将会对全球产生各种不同的影响，较高的温度可使极地冰川融化，海平面每10年将升高6厘米，因而将使一些海岸地区被淹没。全球变暖也可能影响到降雨和大气环流的变化，使气候反常，易造成旱涝灾害，这些都可能导致生态系统发生变化和破坏，全球气候变化将对人类生活产生一系列重大影响。

(二)臭氧层的耗损与破坏

在离地球表面10~50千米的大气平流层中集中了地球上90%的臭氧气体，在离地面25千米处臭氧浓度最大，形成了厚度约为3毫米的臭氧集中层，称为臭氧层。它能吸收太阳的紫外线，以保护地球上的生命免遭过量紫外线的伤害，并将能量贮存在上层大气，起到调节气候的作用。但臭氧层是一个很脆弱的大气层，如果进入一些破坏臭氧的气体，它们就会和臭氧发生化学作用，臭氧层就会遭到破坏。臭氧层被破坏，将使地面受到紫外线辐射的强度增加，给地球上的生命带来很大的危害。研究表明，紫外线辐射能破坏生物蛋白质和基因物质脱氧核糖核酸，造成细胞死亡;使人类皮肤癌发病率增高;伤害眼睛，导致白内障而使眼睛失明;抑制植物如大豆、瓜类、蔬菜等的生长，并穿透10米深的水层，杀死浮游生物和微生物，从而危及水中生物的食物链和自由氧的来源，影响生态平衡和水体的自净能力。

(三)生物多样性减少

《生物多样性公约》指出，生物多样性“是指所有来源的形形色色的生物体，这些来源包括陆地、海洋和其他水生生态系统及其所构成的生态综合体;它包括物种内部、物种之间和生态系统的多样性。”在漫长的生物进化过程中会产生一些新的物种，同时，随着生态环境条件的变化，也会使一些物种消失。所以说，生物多样性是在不断变化的。近百年来，由于人口的急剧增加和人类对资源的不合理开发，加之环境污染等原因，地球上的各种生物及其生态系统受到了极大的冲击，生物多样性也受到了很大的损害。有关学者估计，世界上每年至少有5万种生物物种灭绝，平均每天灭绝的物种达140个，估计到21世纪初，全世界野生生物的损失可达其总数的15%~30%。在中国，由于人口增长和经济发展的压力，对生物资源的不合理利用和破坏，生物多样性所遭受的损失也非常严重，大约已有200个物种已经灭绝;估计约有5000种植物在近年内已处于濒危状态，这些约占中国高等植物总数的20%;大约还有398种脊椎动物也处在濒危状态，约占中国脊椎动物总数的7.7%左右。因此，保护和拯救生物多样性以及这些生物赖以生存的生活条件，同样是摆在我们面前的重要任务。

(四)酸雨蔓延

酸雨是指大气降水中酸碱度(PH值)低于5.6的雨、雪或其他形式的降水。这是大气污染的一种表现。 酸雨对人类环境的影响是多方面的。酸雨降落到河流、湖泊中，会妨碍水中鱼、虾的成长，以致鱼虾减少或绝迹;酸雨还导致土壤酸化，破坏土壤的营养，使土壤贫瘠化，危害植物的生长，造成作物减产，危害森林的生长。此外，酸雨还腐蚀建筑材料，有关资料说明，近十几年来，酸雨地区的一些古迹特别是石刻、石雕或铜塑像的损坏超过以往百年以上，甚至千年以上。世界目前已有三大酸雨区。我国华南酸雨区是唯一尚未治理的。

(五)森林锐减

在今天的地球上，我们的绿色屏障——森林正以平均每年4000平方公里的速度消失。森林的减少使其涵养水源的功能受到破坏，造成了物种的减少和水土流失，对二氧化碳的吸收减少进而又加剧了温室效应。

(六)土地荒漠化

全球陆地面积占60%，其中沙漠和沙漠化面积29%。每年有600万公顷的土地变成沙漠。经济损失每年423亿美元。全球共有干旱、半干旱土地50亿公顷，其中33亿遭到荒漠化威胁。致使每年有600万公顷的农田、900万公顷的牧区失去生产力。人类文明的摇篮底格里斯河、幼发拉底河流域，已由沃土变成荒漠。中国的黄河流域，水土流失亦十分严重。

(七)大气污染

大气污染的主要因子为悬浮颗粒物、一氧化碳、臭氧、二氧化碳、氮氧化物、铅等。大气污染导致每年有30-70万人因烟尘污染提前死亡，2500万的儿童患慢性喉炎，400-700万的农村妇女儿童受害。

(八)水污染

水是我们日常最需要，也上接触最多的物质之一，然而就是水如今也成了危险品。

(九)海洋污染

人类活动使近海区的氮和磷增加50%-200%;过量营养物导致沿海藻类大量生长;波罗的海、北海、黑海、东中国海(东海)等出现赤潮。海洋污染导致赤潮频繁发生，破坏了红树林、珊瑚礁、海草，使近海鱼虾锐减，渔业损失惨重。

(十)危险性废物越境转移

危险性废物是指除放射性废物以外，具有化学活性或毒性、爆炸性、腐蚀性和其他对人类生存环境存在有害特性的废物。美国在资源保护与回收法中规定，所谓危险废物是指一种固体废物和几种固体的混合物，因其数量和浓度较高，可能造成或导致人类死亡，或引起严重的难以治愈疾病或致残的废物。

Protecting the environment and taking care of the earth is something we all should do.

Recently there are a lot of environment has been destroyed, around us there are many people in the destruction of the environment, cut down the trees, the birds were killed, flowers and plants have been burned, it is one thing for our warnings, the forests are disappear in every 375 square kilometers, the desert is evolving, flooded the countless individuals every beautiful homes, precious and there are ancient animals are killed, the panda has now been arrested, and so far only 1000 only, although there are a lot of people have built consciously protection station, but there are still some people for money by hook or by crook the killing of animals, birds no longer common, because being grabbed, trees less, because being cut, please protect them! If you go on like this, again, and the future of the animals we have learned in a book, according to people each with experts observation, day and night, a protective layer in the sky, the ozone hole, is because of the large hole lead to global warming, and the year before become very hot in the summer, many people died in the heat.

All this is because people open super sound emitted by aircraft emissions of waste gas and the car tail gas is left at the trial of toxic substances in the air into the results, if in so doing, the glaciers will melt, make the surface flat area, causing most of the land of the sea submerge.

If you dont stop cutting trees, when the trees were cut down light, desert will evolve, without the tree represents no oxygen, and the air was full of carbon dioxide, make the person cannot breathe, cause a person to cant live.

Please do not cut down trees, let the birds have a home, do not emit waste gas, let us live together in this beautiful earth!

The world is changing all the time, and my hometown is no exception. In recent years, my new eyes have witnessed the welcome changes in my hometown.

The mountain in the hometown changed, the former bald "steamed bread", now green oil; The water in my hometown has changed. Once full of mud and mud, the water is now crystal clear. The road in my hometown has changed. Once the muddy dirt road, now not only became the spacious asphalt road, but also repaired the traffic light; The house in my hometown has changed, and  bungalow, formerly short and small, is now a spectacular high-rise building. The transportation tool in my hometown has changed. Once upon a time, it was the goal of the people to have a bicycle, and now the streets are almost all beautiful cars.

Ah! I am pleasantly surprised to find that my hometown is undergoing rapid changes, and our motherland is also undergoing earth-shaking changes! The change of hometown is a microcosm of the prosperity of our motherland!

I love my lovely hometown!

“保护环境，人人有责。”这句话是否能使我们懂得了保护环境的重要性?同学们呢，人人都知道，地球是和蔼的母亲，年过花甲的她受到人类的严重破坏，地球和人类将会受到严重的威胁。如果地球上的资源被耗光了，我们该怎么办?到时候没有资源让你珍惜了。作为地球的小公民，应该站起来，做一个保护环境的小卫士，告诫人们不要浪费资源。我们有责任保护人类家园，从一点一滴做起，从小事做起，从身边做起，让地球的明天更加美好!。对于保护环境的问题，我提出了以下建议：

一、告诉大人们拒绝使用塑料方便袋，这样能减少白色垃圾。

二、拒绝使用一次性筷子，因为一次性筷子的材料是用树木做的。

三、节约用水，大家要学会循环利用水。

四、爱护花草树木，不在树木上乱写乱画。

五、不要随地吐痰，随地扔垃圾。

同学们!为了在天空翱翔的小鸟，为了游在水里的鱼儿，为了大自然，为了我们的人类家园，行动起来吧!“保护环境，你我共识。”请记住，地球只有一个!

What’s more, we should realize that only from our planet can we obtain our sheltering, food, cloth and so forth.

Over the past years, floods, droughts, landslides, and dust-storms have frequented our planet, the only habitat of human beings. Several days ago, tsunami(海啸) has swept the Southeast Asia, which has caused enormous damage. All these have sounded an alarm to human beings.

The destruction which is caused by human beings has aroused people’s concern all over the world. If we pay no heed to the present destructive human activities, our planet will become of tomb instead of cozy home. What’s more, we should realize that only from our planet can we obtain our sheltering, food, cloth and so forth.

Counter-measures must be taken to curb the destruction caused by human beings. Most importantly, laws must be established to punish those who are involved in destructive conducts.

The earth mother as the cradle of life, human like a spoiled child of the earth. She give us everything we need for life leave her, we will get nothing. Beautiful living environment is the basis of which we live, but now, our environmental protection consciousness is more and more weak. Though, we all know that protect the environment, but not the property of the consciousness of earth, destroy the originally beautiful environment; In fact, in life, as long as pay attention, everywhere can be environmental protection.

In those restaurants everywhere can see around us, the boss in order to achieve "health" standard, and unconsciously extensive use of wooden chopsticks that were made from wood; Cost is huge, hits the verdant trees with bangs fall, only the birds were forced to leave, a group of a group of lovely animals homeless again, but as they didnt see, originally natural ecological environment destroyed by them, just like that. Not only did not have the forest, and animals are not spared. Recently, some cantonese put smart cute little monkeys alive opened the brain had his head down, they looked at each cute little monkey innocent dead, but still, this is what a horrible thing!

We as the master of the earth, if you dont cherish everything now, that this beautiful environment will leave us early. At that time, we will face catastrophe, the earth will be scarred, and hurt; So we should do owners should do, well protect our survival environment, do not deliberately to destroy, remember: to protect the environment, is to protect the future of mankind.

地球母亲就像是生命的摇篮，人类就像是地球的骄子。她，给予了我们生活所需要的一切离开她，我们就一无所获。美好的生存环境是我们赖以生活的基础，可是现在，我们保护环境的意识却越来越淡薄了。虽然，大家都知道保护环境，但却不自觉的掠夺地球的财产，破坏原本美丽的环境;其实，在生活中，只要留心，处处都能环保。

在我们周围的那些餐馆中随处可以看到，老板为了达到“卫生”的标准，而不自觉的大量使用那些用树木做出的木质筷子;为此付出的代价是巨大的，一棵棵青翠的树木随着巨响而轰然倒下，一只只鸟儿被迫离开，一群又一群可爱的动物无家可归，可他们却当作没有看到，原本自然的生态环境就这样被他们破坏。不仅森林没有了，而动物也是不放过。最近，一些广东人竟然把机灵可爱的小猴子活活的把头打开把脑子吃了下去，他们看着一只只可爱的小猴子无辜的死去，却还是无动于衷，这是多么令人发指的事呀!

我们身为地球的主人，如果不珍惜现在的一切，那这美好的环境一定会早早的离开我们。到时候，我们会面临灾难，地球也会伤痕累累，而受到伤害;所以我们应该做到主人应该做的事，好好的保护我们生存的环境，不要蓄意的去破坏，要记住：保护坏境，就是保护将来的人类。

环境保护雅思英语作文

You should spend about 40 minutes on this task.Write about the following topic:

The earth is being filled with waste material such as plastic bags and other rubbish. Is this really happening? What are some solutions to this problem?

Gives reasons for your answer and include any relevant examples from your own knowledge or experience.Write at least 250 words.

model answer:

Over the past few decades, the increasing amount of industrial wastes and household garbage has become a major problem in many countries. People have questioned what caused this problem and what can be done to improve the situation. In my opinion, two of the most critical causes of this waste material problem are the increased consumption and a shortage of space for landfill.

To begin with, modern lifestyle has contributed greatly to the increasing amount of waste and garbage we produce everyday. In other words, we have turned into a materialistic and mass-consumption society where we use more and throw away more than ever before. Moreover, countries are running out of space to store garbage and waste material. In fact, securing land for waste disposal raises controversies in many countries.

To solve this intractable problem, every citizen needs to participate in producing less garbage. For example, we can bring our own personal shopping bags instead of using plastic bags provided by stores and shops. Besides, the government can enforce stricter laws on companies to use biodegradable packaging or use recycled material. Indeed, this alone can eliminate much of the waste which is sent to at land fills. Companies can also contribute by developing new raw material which is recyclable and will ultimately lead to less garbage. One good example of this is that tire companies develop new tires for cars which are not made of rubber but of new biodegradable material.

As discussed above, individuals, business and the government can share the responsibility to reduce the amount of waste material and to save the earth. I hope that in the future our offspring will be better off with the well-preserved environment.

环境保护雅思英语作文

Environmental hazards are often too great for particular countries or individuals to tackle. We have arrived at a point in time where the only way to lessen environmental problems is at an international level.

Environmental problems have reached such proportions that people feel international organizations must be set up to intervene in world affairs to resolve these problems. Whether this will resolve the problem is very unlikely as international organizations are just an extension of human behavior. That is, if human conflicts cannot be resolved at home, then they are unlikely to be resolved at the international level. Nevertheless, international organizations do attract attention to the growing problem of aims of the international community to resolve the issue of environmental pollution and support their cause, I do not believe it is the best or only way to protect the environment; in fact, it is only a small part of what is needed in a global initiative.

All world problems, whether it is environmental pollution, war, energy insufficiency, or famine, arise from the abusive behavior of all individuals. Therefore, the solution to all these problems is the need for a collective consciousness. What is meant by this is that each individual must be aware of the impact he or she has on the world and their unique part to play in this world. After all, if one is happy with his life, he will surely not endeavor to harm the environment or anyone else. His behavior will be that of a responsible individual.

What is needed, therefore, is education. Education is the key to all problems and it starts from pregnancy all the way to adulthood and beyond. Furthermore, education means that children all over the world should be allowed to go to schools with good teachers and where teaching materials and methods can be adapted to each individual. Education means raising children to be responsible individuals.

This may sound like utopia, but it is not: if a country had important problems in its educational system, then it should realize that it is contributing to the worlds problems. These are perhaps long term solutions, but they are more realistic solutions than setting up yet another international organization.

When we are in our classroom after 8：30 in the morning，we should not keep the lights on to avoid wasting electricity since there is enough light in the classroom.And if it is cloudy and rainy and lights are on，we should turn off the lights after school.Another thing we can do is to protect the forest which is reducing.We should use both sides of paper and we should not use paper cups and disposable chopsticks which are made of trees.

All these are the things we can do every day to make our environment better. As long as we insist on doing so，our environment will become better and better.

Its Our Duty To Protect Our Environment

Its our duty to protect our environment.Where do we live?The earth.The earth is the only one place we live in.So you know how important the environment is.

But now,some people are harming the environment,like cutting down trees,drawing pictures on public walls,littering onto the ground.Its terrible if we still do it.

Now,its time for all the people in the society to protect the environment.Its our duty.It needs each of us to make a contribution to improving the environment.We should make our environment more and more beautiful.

导语：近年来,环境保护仍存在许多问题。其中最严重的问题之一是空气、水和土壤的严重污染。下面是yuwenmi小编为大家整理的优秀英语作文，欢迎阅读与借鉴，谢谢!

There are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to people s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reduced with the rapid growth of modern cities.

To protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today.

In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves.

【参考译文】

近年来,环境保护仍存在许多问题。其中最严重的问题之一是空气、水和土壤的严重污染。污染的空气对人体健康有害。污染的水导致疾病和死亡。此外,随着现代城市的快速发展,植被已大大减少。

为了保护环境,许多国家的政府做了很多。已采取立法步骤控制空气污染,保护森林和海洋资源,制止任何环境污染。因此,政府在今天的环境保护中发挥着最重要的作用。

我认为,要保护环境,政府必须采取更具体的措施。首先,它应该让人们通过教育充分认识到环境保护的重要性。第二,应该更加努力使人口规划政策付诸实践,因为更多的人意味着更多的人意味着更多的污染。最后,故意破坏环境的人应该受到严惩。我们应该让他们知道破坏环境意味着毁灭人类自己。

Through observation, I found that plastic bags on peoples harm and pollution is very large. People often use plastic bags: mother to buy food and plastic bags; to shopping malls with plastic bags; in the restaurant to eat rice is also packaged with plastic bags to take home; even I buy stationery also with plastic bags. People do not know what they do to the environment caused by pollution, their own body caused any harm. Such as: people often put useless plastic bags thrown into the garbage, plastic bags in the rubbish will be smelly, so that the pollution of the air. People also throw plastic bags anywhere, a wind, plastic bags flying in the sky, the branches also see the tree is a plastic bag, and even the river there are plastic bags. This plastic bag in addition to pollution of the air, but also polluted our water resources.

We should raise peoples awareness, tell us the neighbors and friends and family together to beautify our environment. On the road to see the plastic bag quickly picked up, immediately took it to the garbage disposal. We want to start from my use less plastic bags, so that my mother every day to buy food or shopping when they first take their own bags, this is not very environmentally friendly? Or can use their own holding things as far as possible by hand, no plastic bags.

As the saying goes: "to protect the environment, everyone is responsible" We have to protect the home environment out of a force.

[关于环境污染的大学英语作文

我国的城市河流和湖泊污染情况是非常严重的,城市河流水有不同程度的富营养化问题。以下是小编给大家整理的形势与政策论文：城市水环境的问题探讨的内容，欢迎大家查看。

摘要: 随着经济快速发展，城市生态形势压力也与日俱增，水环境问题已成为制约社会发展的大问题，环保基础设施建设严重落后，城市生活污染物未得到有效控制，工业污染源未得到严格治理，农业污染日益突出，部分河段水质受污染严重，河水发黑发臭，完全失去水质功能。本文主要对城市水环境治理及污染防治对策进行了分析探讨。

关键词：城市规划;水环境质量;污染防治;对策

城市生态环境是城市宜居水平评价和城市经济发展的重要因素。作为城市生态环境的重要组成部分，城市水环境对生态环境的治理和改善有着重要的影响。受传统经济发展理念的影响，我国城市水环境污染情况不容乐观。而且在城市扩建过程中还造成了大量周边湿地的消失，造成了城市生态环境、水环境的进一步恶化。针对这样的情况，我国近年来加大了城市生态环境治理力度。从城市规划与发展的角度出发，恢复城市周边湿地环境、改善城市水环境与生态环境。

一、城市水环境的基本特点

1、城市用水的特点

生活用水和生产用水是城市用水的主要类型，由于城市人员密集、工业化生产程度高，所以，城市用水需要较高的质量、较大的供水量、稳定的供给，这对城市采水、供水和用水来说有着不同于农村的特点。

2、城市用水的依赖性强

城市由于用水量大、供水要求高，所以，单纯依靠城市区域的供给和开采往往难于满足城市发展的需要，因此，大众城市往往需要从城区周边或外地调水来满足城市的用水需要，“引滦入津”、“南水北调”就是这样的举措。

3、城市水环境脆弱

在我国北方，城市生活和生产用水大都在简单处理或未经处理就直接排放到环境之中，在日积月累的大量污染的影响下，城市水环境受到了严重破坏，并且这一现象有蔓延和恶化的趋势，造成水环境的脆弱和生态的破坏，影响城市深入地发展。

4、城市地下水环境恶化

城市地下水环境恶化来源有两个，一是，城市生产和生活中大量污染源渗入地下，造成对地下水资源和水环境的破坏;二是，城市地表硬化导致城市地面下渗量的减少，在大量开采地下水的同时，没有必要的补充，出现水环境的恶化。

二、城市水环境综合治理方法

1、以人为本，科学发展

把维护广大人民群众的根本利益作为第一点，把群众最关心、最直接和现实的水环境保护问题为重点，转变发展观念，重视生态文明建设，加快建设资源节约和环境友好社会，走科学发展道路。

2、优先保护饮用水源

合格的安全饮用水源是人民生活的必需品，水环境治理应突出重点，优先保护饮用水源，确保群众饮水安全。

3、强化节能减排、效益原则

与区县减排工作挂钩，把COD削减量考核指标纳入到区县水环境治理目标体系中，明确各区县污水处理率、污水处理厂运行负荷率等量化指标。切实保障三个达标，即污水处理率必须达标、污水处理厂的运行负荷率必须达标、COD的减排必须达标。合理安排资金，对节能减排效果明显，有一定经济基础，技术条件成熟，符合国家和行业产业政策的项目优先考虑。

4、治本方针

突出截污治污。河道沿线村镇、企业密集，污染来源复杂。为此，河道治理将坚持“先截污、后清淤、先治理、后换水”的原则，周密排查河道沿线污染来源，大力实施清淤、截污、生态护坡、河岸绿化等措施，加强河道水体自净和生态修复功能;在突出截污治理的同时，各区县还将坚持污水处理厂、配套管网同步建设，大力提升现有污水处理厂运行负荷率，妥善解决污水出路，切实提高河道水环境质量。

5、加强协作，落实责任

市水务局于去年成立了河道水环境考核办公室，将清水工程已治理河道纳入考核范围，各区县按照属地管理原则在本辖区内建立水环境管理机构和相关管理机制，有效巩固水环境治理成果。此外，目前市政府已正式批准本市河道水环境实施“河长制”管理意见，即将公布全市主要河道“河长”名单，构建完善的河道水环境管理长效机制，为今后本市水环境由加强治理向强化管理转变打好基础。

三、城市河流水防治和改善技术的应用

1、底泥疏浚和河床微生态系统修复

在河流洪水、蓄洪功能上,底泥疏浚主要体现在河流利用水面变化增加行洪、蓄洪能力。作为沉积物沉积,有的湖泊水的深度可以被调整,从而减少其调节和存储功能。增加城市河湖疏浚河道水容量后,以确保顺利排出这些河流洪水,保障人民群众的生命和财产安全,也避免了洪涝灾害。底泥疏浚是水环境综合整治的一项重要措施,滇池、巢湖、太湖等水环境综合整治已被广泛使用。可见,合理的疏浚清除污染物,对于生态系统的恢复和重建具有非常重要的作用。

2、人工增氧技术

人工增氧技术是基于城市河流水污染后缺氧的现象,人工的向水体中注入空气或氧气,从而加速水体复氧的进程,提高水体的溶解氧水平,恢复和提高在水中好氧微生物的活力,使河流水的污染物净化,从而改善河流的水质。河流氧气一般使用固定和移动站充氧平台两种形式。河道人工增氧技术的应用,能够使得水质不同时期达到消除黑臭、减少水体污染负荷、促进河流生态系统恢复的目的。

3、调水引流水质改善技术

贯穿城市的内河河网水系,因为控制结构的限制,使得河流水不能够连接到外部的水体,造成水处于静止的状态,当天气炎热的时候,溶解在水中的氧气浓度就会降低,容易导致水质变坏。通过改进水域水动力条件,提高水体污染物的稀释能力,增强局部水体的自净能力,许多城市在水资源利用和部署中,通过跨流域调水工程,解决空间分布不均的问题。

4、植物修复技术

对于河道河流自然恢复应采取生态化措施,主要是通过恢复河岸植被、恢复天然湿地,在河岸种植芦苇、浮萍、睡莲、水生植物和其他湿地植物,以提高水体的净化能力。种植水生植物的城市河流水,一方面能够通过植物的根系的吸收,从而降低和遏制富营养化趋势;另一方面通过种植水生植物,可以也起到美化水体环境,提高城市的景观的效果。

5、生物净化技术

生物净化技术是充分利用天然水体自净的功能,采用人工措施,创造更有利的环境有利于微生物的生长和繁殖,并培养出大量的微生物从而增强水体净化能力,以提高纳污水体氧化降解有机物能力的一种净化方法。目前国内外最常用的生物净化技术是曝气技术、生物膜技术与投菌技术。生物净化技术,其成本低,对环境的影响小,能够有效降解污染物,是水体污染处理的最佳选择之一。生物净化技术及产品的开发,特别是分解菌株的培养也将被筛选到河流水污染控制技术之中,是未来城市水污染防治和治理的发展趋势。将具有特殊分解能力的菌种添加到河边,能够将水体中有毒有害物质分解为无毒无害的物质,从而加速有毒物质的分解、转化,不仅可以提高河流的净化能力,而且也实现了河流的生态修复。生物产品的运用将成为人工增氧、底泥疏浚等现有防治技术的有益补充。

四、结束语

综上所述，我国的城市河流和湖泊污染情况是非常严重的,城市河流水有不同程度的富营养化问题。目前,在城市河流污染环境下,需要完善城市管线网络,并建设污水处理厂,具体的水污染防治技术措施有:底泥疏浚、人工增加氧气、引水排水水质改善、植物修复、湿地水净化技术等河流强化净化技术。能够应对不同的城市的污水状况,使得城市河流水污染的情况得到了有效的控制,促进城市河流的健康发展。
