Boys and girls, do you understand how much environmental knowledge, know? Protecting the environment is the human consciously protect natural resources and make them get reasonable use, to prevent the pollution of natural environment and damage. Now, the earth environment gradually destroyed. Because there are many environmental destruction, someone for reason, there are natural causes. But most people are deforestation, litter and other factors.

As far as I know from the Internet, 30 years from 1950 to 1950, more than half of the worlds forests have been destroyed, one half of the forest land into desert in Africa. Green vegetation is present in the human nature of "being" of life. World the 50 years after the 20th century, however, damage to people and animals live in green environment, green vegetation is in a recession, the global soil loss to increase to 25.4 billion tonnes a year, desertification, soil is at an annual rate of 5 to 7 square kilometers expanded rapidly.

In 1998, through China the earth in the Yangtze river, the songhua river, such as large rivers, lost the past gentle beautiful smiling face, out of ferocious ferocious terror. Raging storms, the roaring river, rolled up the flood peak, and again engulfed entire villages, pieces of land, cities and counties, each factory, a school... Oh my god, this is what a loss!

In recent years, because humans cut down trees, also damage the environment, make the vegetation destroyed, causing the phenomenon of land desertification, soil erosion, etc. Trees also gradually reduce, then, to absorb carbon dioxide, large amounts of carbon dioxide make the air become warm, creates the world present situation: the greenhouse effect.

Campus is always has a beautiful scenery, now everyone dont protect the environment, it makes our environment destruction. Look at the corner of the street is filled with plastic bags, cigarette butts. On the flower beds in the neighborhood is filled with dirt, we should protect everything we have good resources. I have people here dont protect environment under the condition of reverie: one day, the tree my grandfather in the beautiful scenery in a rest, suddenly to a few people, to prepare for a picnic here. Not for a moment here a beautiful environment becomes dirty, but this a few people or ignored. "The men finally walked" the tree grandpa sad cried, alas! The men got the cigarette butts on the grass, the ground filled with plastic bags, bottle. A few days later the tree grandpa dyspnea died because of bad environment.

同学们,环保知识你们了解多少,知道多少?保护环境是人类有意识地保护自然资源并使其得到合理的利用,防止自然环境受到污染和破坏。现在,地球上环境逐渐遭到破坏。环境遭破坏的原因有许多,有人为原因,也有自然原因。不过大多数是人们乱砍乱伐,乱扔垃圾等因素。

据我从网上了解,自1950年到1980年30年间,全世界有一半以上的森林面积被毁,其中非洲的二分之一林地变成不毛之地。绿色植被是大自然赠于人类的“生命之被”。可是,世界进入20世纪50年之后,人和动物赖以生存的绿色环境遭到破坏,绿色植被正在衰退,全球土壤失量现以增加到每年254亿吨,沙漠化土壤正以每年5-7万平方公里的速度迅速扩展。

1998年时,流经中国大地的长江、松花江等大江大河,失去了往日温柔美丽的笑脸,露出了凶猛恐怖的狰狞。肆虐的暴雨,咆哮的江水,卷起了一次次洪峰,吞噬了一个个村庄,一片片田地,一个个市县,一座座工厂,一所所学校……天哪,这是多么大的损失啊!

近几年,也因为人类大量砍伐树木、破坏环境,使植被遭到破坏,造成了土地沙漠化、水土流失等现象。树木也渐渐减少,于是,二氧化碳无法吸收,大量的二氧化碳使空气变得温暖,就造成了世界上目前出现的状况:温室效应。

园里都总有一处美丽的风景,可现在大家都不保护环境,这才使我们的环境遭受破坏。你看街道上的角落到处都有塑料袋,烟头。小区里的花坛上到处都有脏东西,我们应该保护好我们现在所拥有的一切美好资源。我就在这人们不保护环境的情况下遐想:一天,大树爷爷在一处美丽的风景休息,突然来了几个人,准备在这里野餐。没一会儿这里美丽的环境一下变得脏兮兮了,但这几个人还是置之不理。“这几个人终于走了”大树爷爷悲哀的叫着,唉!那几个人把小草上弄上了烟头,地上掉满塑料袋,瓶子。没过几天大树爷爷因环境不好呼吸困难死去了。

篇11: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。

篇12:高楼大厦与环境英语作文

全文共 1472 字

+ 加入清单

in the late 1960s, many people in north america turned their attention to environmental problems, and new steel-and-glass skyscrapers were widely criticized。 ecologists pointed out that a cluster of tall buildings in a city often overburdens public transportation and parking lot capacities。

skyscrapers are also lavish consumers, and wasters, of electric power。 in one recent year, the addition of 17 million square feet of skyscraper office space in new york city raised the peak daily demand for electricity by 120, 000 kilowatts-enough to supply the entire city of albany, new york, for a day。

glass-walled skyscrapers can be especially wasteful。 the heat loss (or gain)through a wall of half-inch plate glass is more than ten times that through a typical masonry wall filled with insulation board。 to lessen the strain on heating and air-conditioning equipment, builders of skyscrapers have begun to use double-glazed panels of glass, and reflective glasses coated with silver or gold mirror films that reduce glare as well as heat gain。 however, mirror-walled skyscrapers raise the temperature of the surrounding air and affect neighboring buildings。

skyscrapers put a severe strain on a citys sanitation facilities, too。 if fully occupied, the two world trade center towers in new york city would alone generate 2。25 million gallons of raw sewage each year-as much as a city the size of stanford, connecticut , which has a population of more than 109, 000。

篇13:当前,威胁人类生存的十大环境问题是

全文共 2072 字

+ 加入清单

(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。

Above all, if we human beings cannot recognize theseserious problems and try our best to solve them soon, we would finally lose theenvironment suitable for us to live. So, it is our duty to protect theenvironment ,but what should we do to protect it?

In my opinion, the first and important thing is tounite all forces ,that is to say---gather all hearts together. Next we shouldprotect and plant more trees, which can dispose of the dust in the air. As forfamilies, it is effective to ride bicycles rather than drive cars. Don’t litteranywhere as you like. In addition, sorting and recycling the rubbish also playan essential role in the protection of our earth. We’d better call on everyone aroundus to lead a low-carbon life, as it may make a difference to the environment.

Thus, it’s high time that we did something to improveour surroundings. Everybody should raise the awareness to protect our motherearth. Let’s appeal to more people to join us.

All in all ,there’s no doubt that keeping the balanceof human and nature ,we will benefit a lot.

The word "college student" is used in most people to highlight the sparkle of the garland, how many people envy, and how many people want to have it!

Since college is such a thing that can change fate, many people think of college students "should". As more and more college students, college students did not seem so popular over the years, even when looking for a job, where the starting point is not higher than others, but this kind of idea.

Indeed, the number of college students is more than a year, a year employment difficult year after year its a question of reality, in the tide of market economy, how to face the society accept vocational selection, out of their way is before each choosing a career is a big exam. In the ordinary peoples eyes to wash the feet is the people to do the errand, especially now some of the bathing place business is improper, is subject to the secular prejudice. A college student to lay down their own shelves, do something that makes people do not understand the work, which in addition to using the learned knowledge in practice, more college students is faced with the severe employment situation, based on reality, tailored for take a way can reflect their own value.

But li didnt do it. She chose a career that didnt fit her own identity -- a foot wash

In some peoples opinion, labor is the difference between high and low, so when it happens, it will cause a great social explosion and become an eye-catching thing.

Indeed, the decades of hard work have yielded a so-called "humble" profession!

But I dont think that anyone has equal dignity, no matter what their social identity is. Society cannot see which profession, every profession has every occupation effect!

Cleaner -- often seen, but, have you thought about it? Without their diligence, what is the beautiful environment now?

Window washers - often demeaned, but, have you thought of it? Without their sacrifice, what is the bright vision now?

......

All in all, the people who work for every job are a good example of society... At least they serve the people with their own sweat!

There is an ideal "choice of door to the door", there is also the choice of "high school is low", and the choice of self-employment, no matter what choice do not want to overreach, should seize the opportunity. In order to start from the actual situation of society and myself, we should make a point of reality, which is only the condition, and the interior should be the key. Choosing a career may not necessarily be the case, but its up to you to grow. If you want to do well in your career, you will have a sense of perseverance and dedication to achieve your goals and social recognition.

So, career choices dont necessarily have to be so big! Live a wonderful self!

现在的环境,被糟蹋的非常厉害,工业污染特别严重,现在人为污染也很严重,我们呼吸不到新鲜的空气,看不到那些美丽的景色。路边的小草,再也没有往日的生机;房边的大树,也变得不再青翠,就连城市的河水,也浑浊不堪。

我来为大家说一件我亲眼看到的事件吧。放暑假了,父母带我去美丽的普吉岛玩耍,第三天,我们乘船来到pp岛,在船上,我亲眼目睹了一位领队吐痰到海里,那海水是多么的清洁,干净呀!小鱼,珊瑚都尽收我的眼底,而在这种情况下,吐痰到海里,真是让人看不下去,他还吐了“两”次呢!虽然这海水是那么的纯洁,干净,但是假如每个人来这里都吐一口痰,那这海水会多么的肮脏,浑浊和难看呀!

我们要保护环境,还要不伤害环境,不要像那位领队一样这样的破坏,伤害环境。我们是人类,应当保护我们赖以生存的地球。如今的地球已经“发烧”了。

在我们的生活中,我们应该注意从中的点点滴滴,扔垃圾时扔到垃圾娄里,不要随地吐痰,不要随意扔烟头到树林里,等等,有许多许多,只要我们努力,就一定能让我们的家园重复青春的。

不伤害环境,从我做起。
