我的家乡在南平,1984年那的房子是木头盖的,慢慢的变成砖头盖的,再慢慢地变成了水泥盖的。

以前森林里的树林是郁郁葱葱的,小溪的水是清澈见底,天空是湛蓝深远,空气清新甜润。可不知为什么人们突然有了一种想法:家里的柴不够用了就上山砍树,可有的人一生就想着富贵,想用树木盖的房子,过了几天这消息传开了,变成了大家都来砍树。可有的人不砍树却到小溪边洗衣裳,就这样一年年一代代,森林的树渐渐的变少了,小溪的水变成了乌黑的溪水。突然,有一天下了一阵大雨,人们有用木头盖的房子已经快支撑不住了,有的房顶被大风吹翻了,有的家里漏水了,还有的家里已经快要倒了,外面儿的汽车东开西开那烟雾都要把人们给熏死了。

过了几年人们才明白树不能砍,溪水不能污染。森林可以放新鲜空气,会把不干净的空气吸入,吐出干净的空气。

知道了这事,人们立即行动起来,有的收集树种,有的正在给小树浇水,还有的还在挖土,还有的在清理小溪。

过了几年,森林又郁郁葱葱,溪水又清澈见底,天空又湛蓝深远,空气又清新甜润了。

保护环境英语作文一:

Topic:

Environmental problems are as big as not for individual country or individual people to address。 In other word, we have reached the stage that environmental problems be solved for international view。 To what extent do you agree or disagree?

In recent years, many nations have bee more aware of the environmental issues each nation faces, such as air and water pollution。 The question is, are the environmental issues a national problem or an international problem? It is my belief that the environmental issues have grown to the point of being an international problem needing international cooperation to resolve。

Because of the differences in environmental policies, resources and technology, international cooperation could provide quicker results and have a greater impact on bringing resolution to environmental problems for nations of differing environmental policies and of lesser resources and technology。 By pooling international resources and technology to address the environmental problems, the disadvantaged nations are provided the assistance needed。 Otherwise their environmental conditions deteriorate ultimately affecting the resources and environment of the world as a whole。

One of the difficulities to an international resolution to environmental issues is the difference in individual nations view and policies toward environmental protection。 In order for international cooperation to occur and succeed, the nations of the world must submit themselved to international standards and supervision by an international mission elected by the participating nations of the world。 All members must agree to abide by the standards established。

The environmental issues facing each country are not unrelated to the well being of the rest of the world。 The impact is long term and international in scope。 Without international cooperation and agreement to address such environmental issues as glacial melting at the South Pole, depletion of the ozone layer, water pollution, air polution, etc。, the environmental conditions of the world will deteriorate to the detriment of every nation, not just those that ignore or lack the resources and technology to resolve their individual environmental problems。

As part of the same planet, it is the responsibility of each individual and nation to protect the global environment。 Only international cooperation will provide the timely solutions and the effectiveness needed to stop the deteriorating global environment。

But in real life, some people still dont too seriously, think small, in my opinion, environmental protection should start from the pretty little things. I have experienced such two things: one day, I go to the supermarket to buy things, quickly to the door of the supermarket, see several send out flyers, see to, see cars, but some people dont, casually throw on the ground, I used the paper in the trash. Saw the two men, the propaganda time with glue on the wall, from a distance, like pieces of "psoriasis" while they do not pay attention to, and I took out my skills "tearing work", ha ha, I get rid of a large "psoriasis" is. At another time, I play in the bottom of a floor, find the distance on the grass up whereas white smoke, a closer look, it turns out that there is a group of children in our class burning grass, grass black a large, I hurriedly stop as a big brother, and about the dangers of fire and the importance of environmental protection. They are ashamed, quickly the coming water from the nearby end extinguish fire, finished burning grass action.

We human beings are living on a planet, that is the earth. On earth, have for the oxygen we breathe, there are dense forests, vast grasslands, boundless sea, all kinds of animals, constitute the beauty of nature.

环境保护,这个话题,可以说是家喻户晓,人人皆知。但在现实生活中,一些人还是不太重视,认为微不足道,在我看来,环保要从件件小事做起。我就经历过这样两件小事:有一天,我去超市买东西,快到超市门口时,看见有几个散发宣传单的,见人就给,见车就放,可是有些人却不要,随手就扔地上,我过去将纸扔进垃圾箱里。又看见两个人用胶水将宣传单贴在墙上,远远望去,活像一块块“牛皮癣”趁他们不注意,我又拿出我的绝活“撕纸功”,哈哈,“牛皮癣”被我除掉了一大片。还有一次,我在楼底玩,发现远处草地上冒出了缕缕白烟,走近一看,原来,是我们班一群小孩在那里点火烧草,草黑了一大片,我以大哥哥的身份连忙制止,并讲了火灾的危险性和环保的重要性。他们羞愧难当,赶忙从附近端来水把火熄灭,结束了烧草行动。

我们人类都生活在一个星球上,那就是地球。地球上,有供我们呼吸的氧气,还有茂密的森林、辽阔的草原、无边无际的海洋、各种各样的动物,构成了美丽的大自然。

我想大声呼吁人们:地球属于我们人类,属于我们大家,只要用我们的双手,从我做起,从人人做起,保护环境,爱护地球上的自然资源,让清澈的塘水依旧流淌在家乡,让花儿依旧那样鲜花盛开。

人类啊,是应该觉醒的时候了,睁开眼,看看我们的周围,这是我们的家园啊,让我们从此金盆洗手,用自己的双手,用自己的智慧,用自己的良心,为我们的子子孙孙留下一个和谐、美丽的家园吧,让我们为我们世世代代的绵延生存做出一份努力吧!

Last Sunday my father and I went fishing along a river. We found the water so dirty that we could hardly catch fish in it.

A lot of factories along the river always poured their waste water and rubbish straight into the river which made the river water polluted. In this way most of the fish in the river were killed.

If the river water all over the country is polluted like this, no living things will exist in the water. As we all know, environmental pollution does great harm to living things and human beings. Now more and more people have come to realize how serious this problem is. Our government is doing her best to take measures to fight against pollution. We expect that the water in every river will be made cleaner and cleaner before long.

新世纪,祖国日新月异,咱们小区了不落后。瞧!汽车穿梭往来,高楼鳞次栉比,万物焕然一新……

我听妈妈说,原来这儿可不是像现在这样繁荣昌盛。以前这里是一片荒芜的农田,在旁边有一家小机械厂和几户人家。人们外出走着泥泞的小路。到了晚上更是死一般的寂静,伸手不见五指;人们煮饭的炊烟呛得人喘不过气,熏得人睁不开眼。如果下雨天,雨淋到农田,水出不去,就会导致禾苗淹死、腐烂,发出一股令人厌恶的臭味,但如果是旱天,出会造成禾苗干旱而死。所以,这里是一片瘦瘠的农田。

后来,小机械厂逐渐扩大,变成国家企业,就把这片瘦瘠的农田建筑成一座繁华的小区。

现在,我们生活的小区已旧貌换新颜,一幢幢楼房拔地而起,玉柴大厦巍峨耸立。厨房里也安装了抽油烟机,不会再呛得人喘不过气;走出家门,更是一片繁荣的景象,车水马龙,灯火通明。放眼望去,像星星一样耀眼;现在,琳琅满目的超市、商店给我们带来了方便。社区还建设了美丽的花园,为了让大家在玩的同时也能够锻炼身体,于是在花园里一阵阵笑声;每到早晨,人们都会纷纷出来锻炼身体,有的跑步,有的舞剑,有的打太极拳……其它小区的人也闻名而来,我简直为我生活的小区感到骄傲。

这就是昔日农田的小区,经济发达给它镶上了一道金边,在众区之中绽放光彩,你难道不为它感到骄傲吗?

During the day, the light shining, on high-rise buildings with light golden richly, the window of white flashing dazzling sunlight, bright dont open your eyes; Traffic on the road, a bustling crowd stepping hurried footsteps, the whole city from sleep wake up. Im wandering on the streets of the city, looking at all kinds of pedestrians pass, are waiting for the bus commuters, leisurely walking the dog back, energetic child. Busy car sound, buzzing voices be heard, opened the prelude of city color.

The environmental pollution is worse and worse /more and more seriously today. Water is polluted ,we have no clean water to drink Many trees are cutting down, some animals is getting less and less.Some factories is poring dirty air in the sky , the population is increasing faster and faster ,resources is getting less and less…etc. Not only does it affect our lives and health, it also has a great affection in the future.

The first fact I worry about is noise pollution. People can"t sleep well if there is too much noise. That"s why so many people prefer to live in the countryside rather than live in the noisy city. I suggest all the factories and cars shouldn"t make terrible noises. If they make terrible noise that isn"t allowed, they will be fined, and we can also produce the cars which can"t make terrible noise.

The other pollution is rubbish pollution. If everyone makes so much rubbish, one day we may live in a world filled with rubbish. Some people throw the waste paper about. I suggest rubbish should be put into different kinds of dustbins or paper bags.

篇9:形势与政策论文:城市水环境的问题探讨

全文共 3055 字

+ 加入清单

我国的城市河流和湖泊污染情况是非常严重的,城市河流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。

There are still many environmental problems in recent years.One of the most serious problems is the serious pollution of air, water and soil.The polluted air is very damaging to peoples health.Polluted water causes diseases and deaths.More importantly, the vegetation has been greatly reduced, with the rapid growth of modern cities.

In order to protect the environment, many governments have done a lot of work.Introduced legislation to control air pollution, protect forest resources and Marine resources, and stop any environmental pollution.Governments, therefore, are playing the most important role of environmental protection today.

I think the government must take more concrete measures to protect the environment.First, the government should make the people fully aware of the importance of environmental protection through education.Second, more efforts should be made to implement policies on population planning, because more people mean more people mean more pollution.Finally, those who intentionally destroy who should be severely punished.We should let them know that destroying the environment means destroying humanity itself.

【翻译】

仍然有很多环保问题在近几年。最严重的问题之一是空气,水和土壤的严重污染。污染的空气严重损害人们的健康。污染的水引起的疾病和死亡。更重要的是,植被已大大减少,随着现代城市的快速增长。

为了保护环境,许多国家的政府都做了很多工作。介绍了立法措施控制空气污染,保护森林资源和海洋资源,制止任何环境污染。因此,各国政府正在发挥环保今天最重要的作用。

我认为,为了保护环境,政府必须采取更具体的措施。首先,政府应该让人民充分认识到环境保护的重要性,通过教育。第二,更应努力把人口规划实施的政策,因为更多的人意味着更多的人意味着更多的污染。最后,那些故意破坏谁应该受到严厉惩罚的环境。我们应该让他们知道,破坏环境就是毁灭人类自己。

还记得一年级刚开学的时候,一栋栋灰灰的教学楼,旧旧的格致楼。当一年一年过去后,有了很大的变化……灰灰的教学楼变成了一栋栋红白相间的、整齐的教学楼。操场变得更大了,跑道也变成了塑胶的……而且现在在的西校区教学楼的顶上还有一个钟,看起来优雅美丽。进了教室第一映入眼帘的就是一排排整齐的小柜子,那是给我们放一些书、工具等的东西,有了柜子,抽屉就不会向以前那样赛的满满的喽——我们再往前看,是一个大大的黑板,后面还藏着一块白板。而且每两栋教学楼之间还有一棵大大的桂树呢,在上课的时候就能闻到一股股桂花香。学校的变化真大呀!

希望我们的科技能越来越发达!

现在,我们家乡环境越来越差了,空气不再那么清新了,河水不再那么清澈了。我发现这是人们缺乏环保意识造成的。

有一天,我走在回家的路上,突然,一个香蕉皮从我眼前飞过。我转身看了一下,是一位叔叔吃完香蕉后,随手把香蕉皮扔到了地上。我跑了过去,对那位叔叔说:“叔叔,我们不应该乱扔果皮,那会污染环境的!”叔叔不以为然地说:“不就扔了一个香蕉皮吗,那会污染环境吗?”我听了后很生气,捡起香蕉皮,指着说:“如果每个人一天扔掉一个香蕉皮,那地球不就成垃圾站了吗?”之后,那位叔叔的脸变的通红,把我手中的香蕉皮扔进了垃圾桶,然后摸了摸我的头,说:“哎,现在的小学生可真不得了!我们大人还没有小学生有环保意识呢!”我笑着说:“你们大人有能力,也许保护环境比我们小学生还好呢!”我和叔叔都高兴地回家了。

通过这件小事让我明白了只要人人都保护环境,家乡的环境就会变得更加美好。所以,我们应该保护环境,要知道,保护环境就是保护我们自己呀!

改变,对于生态环境是一种理所当然的虚幻改变。对于人呢?也是这样的。比如说从淘气变为乖巧。要是说我们的环境,那真的有很大改变,之所以改变呢,那是有原因的。

每当我早晨醒来的时候,我吸入的那是一种让你神清气爽的空气。顿时,让你觉得舒服,神采奕奕。而如今,来到城市时,空气是多么难闻和臭水沟一样,整个城市充斥的是一股烂垃圾的气味。如果空气如物品一样的话。那,吸入的都是灰尘与污染的灰色气体,让人闻着就不舒服。况且也没有乡下的清爽,在乡下的时候,我会跟爷爷到树林里玩耍,玩的那叫一个“爽”。我们还会去田野里捉蚂蚱,“哎呀”一声惨叫,我摔进了泥坑里变成泥娃娃。我们有时候还会到小河里捡田螺那是一场多么快乐的一天……可是,现在再也没有树林了。因为树不断的减少,做成了有用的建筑用品。我们也不能在田地里捉蚂蚱了,那是因为田地都变成高大的房屋。至于,捡田螺也是能的,但是谁就不知道是不是纯净水了,不过,现在的环境唯一的好处,那就是让我们过上了幸福美满的生活。我也希望我们不要乱丢垃圾。不要让环境变得更加难看,比如风来了,地上都大量飘着塑料的与垃圾。让环境卷入了“白色危机”当中。环境的改变,真的是变化的太大了。环境的改变也不是不好,那是说明了我们中国的技术正在蒸蒸日上。

环境,是一个定时,你如果破坏了它。你们的后果将会是悲催的。

“宁夏黄河九十九道弯”。它的美丽富饶人们一直在传唱,我的家乡就在黄河边上,它哺育着一代有一代的黄河儿女。

我小的时候黄河两岸是个美丽的地方。绿油油的树木栽满了黄河的岸边鸟儿叽叽喳喳的唱个不停,鱼儿在水里自由自在的游动。岸边种着各种各样的庄稼,孩子们在田边玩耍、嬉戏。人们在岸边垂钓,欣赏着对岸美丽的风景。汹涌的黄河水奔腾到了远方,这生机勃勃的一幕构成了美丽的画卷。

随着人们肆意的破坏环境,黄河的环境也随着发生了变化,它变得脏乱不堪。上游的水量不足,再加上人们过度使用黄河水,使黄河断流了。游客与居民们随手乱扔垃圾,让黄河中漂浮着大大小小的垃圾袋,工厂排出的大量废水,使黄河水质发生了改变。黄河里鱼儿的种类越来越稀少,河边随处可见露出了白白的肚皮的鱼儿。成堆成堆的垃圾垒在黄河边上,臭气熏天,他们污染了土地使岸边的树木都枯死了,在黄河岸边会干都一片死气沉沉。天仿佛不是蓝的,水仿佛不是清的。

不仅仅只是黄河。大自然许多地方-都遭到了人类的破坏山不在绿了水不在秀了。人们住在生态环境恶劣的地球中,我们大家有没有想过,破坏大自然最终破坏到的还是自己呀!我们喝的将回是受过污染的水源,我们吃的将会是受过污染的食品生活在污染的环境中的将会也是我们。我们的死可能也是我们自己造成的人类醒醒吧!快从现在开始保护我们身边的每一块土地。

时代在进步,家乡的变化也很大。

原来破旧的楼房现在都推平了,做了新小区。原来我们真累只要东华东这一家超市,现在可好了,又有了时代超市,近期又开张了商之都。购物更方便了,个更加实惠广泛了。还有东西街繁荣昌盛,没事逛逛也非常好。我们城关小学也建了一个分校,在贵中分校隔壁。

现在我家也搬了,原来所在的芙蓉苑小区,没有保安,车也乱放,环境非常不好。现在所在的汇景小区可好了,每天有保安叔叔看院门,并且不断在小区巡逻。家家户户都有固定的停车位,小区的绿化也很漂亮。

我住在利代村,前几年我村的道路特别烂,特别是阴天下雨的时候特别难走,我躲在屋里不想到外面去。

自从2011年上级支持我村修路,我们的农民每家每户也都拿了许多钱为我们村修路,还开了一条很宽的大街,我村共修了南北两条大街,东西五条大街,再也不怕难走了。每条街都整整齐齐路面平的像镜子一样显得特别漂亮,

今年3月15日西安交通还组织了七十名员工来为我们村打扫卫生,我们村的人热情接待了他们,他们也对我们特别有礼貌打扫得特别干净,把我们村的每个角落修的特别整齐。我们村改变了新的面貌更重要的是感谢上级领导对我们利代村的大量支持。

我的家乡这些年的垃圾处理有了很大变化

原来的乡村道路上没有垃圾桶,人们走在路上垃圾没处扔。有的人就直接扔在路边上,有的扔到小河里头去了,经常会见到苍蝇”嗡嗡嗡“地乱飞。每家每户的垃圾都是自己处理,要么烧掉,要么就自己找一个地方堆放。烧的东西里面有不能烧的,比如塑料,烧出来对环境有害处,垃圾堆放的地方则散发着臭气。

后来,人们认识到了垃圾的问题,就做了一些改变。

在乡村道路上,人们每隔一段距离就设置了两个垃圾桶,一个是“可回收垃圾”,一个是“不可回收垃圾”。人们就把垃圾扔到垃圾桶里,道路就变得干干净净的了。

村里给每家每户发了两个大垃圾桶,家里的垃圾全部集中放置。最初人们需要拎着垃圾桶去专门指定的堆放垃圾点去倒,那里的垃圾又需要一段时间才能被处理掉,走在旁边总能闻到恶臭,对环境也有影响。而现在,有了专人每天清晨来把垃圾收走,送到指定的地点进行集中处理。

我的家乡不但对垃圾进行了专门处理,还对养猪等养殖户进行管理,不让他们把废水倒进河里,还常常有人自动到河边去捡垃圾……

现在我的家乡环境越来越好了。

我的家乡原本是一个美丽的小村庄,清澈的小溪。不知过了多少年,小村庄变成了大城市,汽车尾气到处都是,严重污染了空气环境。家乡从前的小河变成了垃圾河,河里活蹦乱跳的小鱼都死了。还有的人为了省事,不到对面垃圾桶扔垃圾,反而丢到了地上。有一些人为什么大么爱护环境,一看到地上的垃圾就丢到垃圾桶里去?我们应该向他们学习,不该乱扔垃圾,应该保护环境。

在此,我想对不爱护环境的人提一个建议:“不要乱丢垃圾,现在城西里有雾霾,这是大自然对你们的警告啊!”

The twinkling of an eye, the elementary school six years has quietly but go to, my side there are many, many items are in change as time goes by, but the most obvious changes in my hometown - build.

Remember in elementary school, a grade one the way home or small TuDao, whenever it rains, the road will be muddy, a walk would step a foot mud, so at home when it rains, go out to buy things or have things out, to Wellington boots, or you go out, come back after your feet must be turning into mud strange feet.
