当今社会正以迅猛之势飞速发展,归根到底是高新技术产业的进一步深化。不容乐观的就是环境与发展之间的问题还没有得到彻底根除。

众所周知温室气体的大量排放,至使全球气候气温逐年上升,呈现出愈演愈列的反弹态势。由此带来的南极冰川溶化问题不容回避。环境问题不仅仅体现在二氧化碳等温室气体排放量上,也表现在含氟物质的大量排放上,严格控制这些有害气体的排放已经刻不容缓。对于二氧化碳等温室气体,当前我们只能用节能减排的传统方式进行限制。在以后的某一天一定能够实现科技引领生活,技术革新环境的革局,正确处理环境与发展之间的问题是一项重大的历史选择。我们不能因为要保护环境而舍弃经济建设这个中心点,也不能因为只追求经济建设而忽略环境变化带给我们的不利因素。高端领域科学技术的发展非常迅猛,已经势不可挡。所以它也必将荡涤整个社会生活的每一个角落。环境问题依托于高新技术的发展众望所归,只有从根本上解决技术革新的问题,能源的优化问题,才能实现当前技术能源的合理配置有效的遏制温度上升带给我们的幅面影响。

环境问题这个关系子孙后代的千秋事业不能忽视。一味从自然界索取,必将被大自然所惩处。可持续发展战略的实施使我们有更多的时间精力去实现高新产品的研发。能源问题必须摆在首位,煤、石油、天然气等非可再生资源日趋减少,而在这个高速发展的社会,对资源的需求量去于日俱增,资源与经济的发展几乎形成了相互制约的关系。非可再生资源我们只有减少开发量,为子孙后代赢得宝贵的发展时间和资源利用。主要的也是减少人为的气体粉尘排放量,使空气质量维持在良好的标准范围。而可再生资源的利用正逐步向成熟期过渡,前景是非常美好的。解决这些问题最好的方式就是不污染,这一点相信只要在这些问题上达到绝对的科技含量是能够解决的。太阳能、风能、潮汐能、水能、地热能、核能等等。如果这些合理有效的加以利用必将给我们的生活提供源源不断的能量。

百年大计,千秋大业。行之有效的措施还是用高新技术促进这些产业的发展,这样必将带来一劳永逸的好处。有氟物质的排放直接影响大气层中的臭氧层,臭氧层空洞使地球直接裸露于紫外线的强照射之下,幅射随之有很大的加剧。对地球上的生物都有很大损伤,而臭养层破坏主要是大量使用有氟冰箱的结果。而以现在的科技足以杜绝用有氟冰箱继而用新型高效节能的冰箱取代,这就有赖于各个国家统一协调,共同努力。只有这样才能从根本上解决这种危机。

当今社会环境问题最令人关注的就是温室气体的大量排放和氟氯烃等气体的排放,国际社会保护环境的基本框架不能改变。而其他的污染都存在很大的区域性,目前就是各个国家自己关注自己环境变化带给自己的影响,这些就要靠自己解决自己的问题了。

We should take good care of the environment, protect the nature.

The earth is the only place we live, is our home. We cant because at that time the interests and her dishes in our hands. Now the earth is in danger, forest fewer and fewer birds, beautiful natural environment is missing, Bridges oxygen to feed the fish in the river without artificial is about to turn over the pool. Now more dust storms, epidemic, fatigue life of people ended almost disappeared, all kinds of cancer eating away at the us one after another of the earths people.

Back to the old people say the water bridge the somebody else, charactizing a fine spring day, how nice. Now you are "small garden path alone wandering" thats impossible.

Have seen such a report: the Japanese popular a kind of "pain pain disease", no root, for passive house got the disease will be walked into the underworld. At that time, Japan was the panic in the medical community, chasing the SuoYuan, chase ever discover Japanese like to eat fish, the fish love to eat garbage pollution, garbage pollution is Japanese poured into Japan into the sea. From this story, we dont speak Japanese, but should get some enlightenment, the deterioration of environment is referred to in a long-term accumulation, is also caused by everyone involved. Blessing is everyone to leave, a curse is everyone leave, this isnt a person. So take good care of the environment, everyone duty, protect the natural, leave the offspring.

Now I am going to call for everybody, we each member of the earths, let us act now! Good care environment, protect the natural, leave f offspring!

我们要爱护环境,保护大自然。

地球是我们人类唯一赖以生存的地方,是我们的家园。我们不能因为一时利益而将她断送在我们手中。现在的地球危在旦夕,森林少了,小鸟少了,美丽的小桥流水的自然环境不见了,河里喂鱼没有不人工供氧就要翻池了。现在沙尘暴多了,流行病多了,劳累一生的人们颐养天年的几乎不见了,各类的癌症蚕食着我们一个又一个的地球人。

回想老人们说的小桥流水人家、鸟语花香天下,是何等的惬意。现在你要“小园香径独徘徊”那也是不可能了。

曾见到这样一个报道:日本流行了一种“痛痛病”,查无根,找无源,得了该病就要走进阎罗殿。当时日本医学界真是着了慌,追本索源,追到底发现是日本人爱吃鱼,日本鱼爱吃污染垃圾,污染垃圾是日本人倒进日本进海里的。从这个故事中,我们不说日本人该死,而应得到一点儿启示,环境的恶化是人们长期积累所指的,也是人人参与所致的。福是大家留的,祸也是大家留的,这不是一个人的事。所以爱护环境,人人有责,保护自然,留福后代。

现在我要呼吁大家,我们地球上的每一个成员,愿我们立即行动起来吧!爱护环境,保护自然,留福后代!

篇3:二胎问题英语作文

全文共 2273 字

The proposal is from Wang Yuqing, a deputy director of the Committee of Population, Resources and Environment.

He is being quoted as saying he favors a gradual opening of a two-child per family policy, and says he believes the current limitations will be lifted by the end of the five-year plan in 2015.

The current family planning policy was initiated in 1979 to control Chinas rapidly growing population.

But some negative side effects have emerged, including a rapidly aging population.

Peng Xizhe is the Director of the Institute of Population Research at Fudan University.

"The one-child policy has fulfilled the goal initially set. Negative effects will pile up if it continues."

The President of Renmin University, Ji Baocheng, claims the labor force population between the ages of 28 and 40 will be halved in 10 years.

As an example, in Shanghai, which has the highest urban population in China, the number of Shanghai natives -- as in those with a Hukou -- has actually been dropping for the last 17 years in a row, even though the citys population has been increasing.

A possible reason for Shanghai parents not choosing to have a second child could be the rising cost of everyday expenses, particularly the cost of education.

"I dont think Ill have a second child if the limit is removed. Im simply a wage-earner, and I find it difficult enough to raise one child, so I wont consider the second."

But at the same time, there are still people who think it would be nice to have two children.

"I will think about it. A lot of parents now are the only child in families, to have two kids means they can look after each other in the future, and of course, therell be financial burden."

One-Child Policy has been relaxed in certain ways over the years.

In cities such as Shanghai and Beijing, if a couple is both the product of the one-child policy, theyre allowed to have two kids.

Certian ethnic minority groups have been exempt from the rules entirely.

And families in rural areas whose first child is a girl are also allowed to have a second child without punishment.

It remains unclear as to how the proposed two-child policy will work, though its being suggested that several big cities will be selected to try it before its brought in around the country.

For CRI, Im Wang Jing.

距离比赛的日子一天天逼近,我的手中握着一个时间沙漏。沙粒一点点从指尖流逝,我却手足无措,半点解决问题的办法都没有。

对于弹钢琴,我还是个新手。大概是天性使然,我总是自卑得认为自己无法完成。这种潜意识阻挡了练琴的信心,更惶恐是,这是我第一次接触大型比赛。再说,比赛挑的曲子名为《小丑》,这首曲子,听者悦耳,弹者流泪,情感难以把握。音调跳跃性也极大,每每弹奏完上一个音,就找不到下一个钢琴键在哪里。

琴房的老师日日陪伴着我,教我如何解决这个问题。可我像榆木脑袋,不开窍,最后老师只能叹口气告诉我:练琴,最关键还在于你的心态,意思是让我自行解决。

望着一圈又一圈转动的分针,我意识到时间正在飞速流逝。这一次的训练也即将结束,可我还是无法调整心态背谱子。我想生气,却又找不到任何发泄的东西。这种像是掐了把空气什么都没有的无助感,让我弹错了几个琴键,门外的老师叹了一口气,说训练时间结束了。

就在这时,我突然意识到,练琴,本就是一件难事,难道就只有我一个人记不住谱子?这仅仅是我一个人的烦恼,其他参赛选手就没有?这个时候,就看谁在坚持,只要不放弃,就有胜出的可能!那一股不服输的劲儿冲进我的脑海,于是我决定我再加练两个小时!

暑期的太阳永远是明艳照人,窗户上的玻璃形同虚设,阳光还是准确无误地投射到我身上。热浪肆无忌惮地汹涌而来,但我仿佛感受不到了,眼中只有那黑白琴键,心中只有那个谱子。妈妈以前说过的话在我耳畔响起:用心融入进去,你就可以完成。她的话像一碗心灵鸡汤,不断温暖着我的内心。

我仿佛化身成了那个小丑,化着夸张的妆容,穿着滑稽可笑的小丑服,跳跃在琴键之间,一会儿是这个白键,一会儿是那边的黑键。终于,我成功地完成了这一曲《小丑》。我长吁一口气,抬头正望见老师惊讶却十分满意的表情。这时,我才发现我竟然在不知不觉中背下了琴谱,不再是那个畏首畏尾的新手,而是个自信的表演者。

夜凉如水,但我心中充满温暖与感动,我仿佛望见琴键中站着一个其实很英俊的小丑……

愿不愿意解决群众问题是态度问题,能不能解决群众问题是政策问题,解决结果的好坏是水平问题。作为办公室人员,提高为群众解决问题的能力是非常关键的。这方面要有前瞻性,预则立,不预则废。要及时掌握信息,综合分析情况,做到事前能预测事态的发生、发展,事中运用科学方法,灵活应对,真正做到会办事、巧办事、办成事,产生事半功倍的效果。要追求效率,能够当面办理的事情,一定要做到立行立办、有问必复、限时办结;不能办理的事情,一定要耐心答复,及时疏导和引导,不能延滞在办公室内。本人在办公室工作多年,接触群众的机会多,了解群众的情况也多,发现来上访的群众大多是有困难的弱势群体。对待这类上访人员,在政策范围内应尽量给予照顾,帮他们排忧解难,有利于解决息访问题。去年年近放春节假的时候,清江桥乡的一位村民来县委办公室上访,他说要找县委领导解决个人的困难,如果书记不在家,就要我告知书记的电话号码。我把他请到我的办公室,耐心听取他的想法,他说他老婆生病花了不少钱,种的土产品又卖不掉,没有钱过年,有关部门又不帮他,只好找县委书记给他解决难题。我很同情他,当即拿出几百元给他,又答应为他推销部分土特产,他很感激而又高兴地回了家。急群众之所急,解群众之所难,是做好群众工作的一把金钥匙。

The population of the earth is increasing very fast. Humans must make the earth support the increasing population. This has made it necessary for agriculture and industry to develop rapidly.

Such a rapid development produces more and more waste, which goes into the water, the soil and the air. Some of it is made harmless. However, where there is too much of it, the poisonous waste may do great harm to the things around the people.

When farmers add fertilizer to the soil to make plants grow better, or use poison to kill pests, poison is sent into the air, the water and the soil. When birds, fish and people eat the grain, drink the water or breath the air, harm will be done to their health.

The air in big cities is often made very dirty by cars and factories. Millions of tons of waste and poisonous gases are sent into the air with the smoke. In some places, little is done to make the smoke clean before it goes into the air.

Fortunately, people are beginning to realize just how serious the whole situation is. In many countries, laws have been made to stop factories from sending out poisonous gases.

篇13: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。

环境污染是当今世界上最大的问题。请根据提示,用自己的话说说怎样保护我们的水资源。

(1) 生命离不开水资源 (2) 饮用水在减少 (3) 水污染严重(4) 应该保护和再利用水

We cant live without water, but now the water was polluted. It is the biggest problem. It influences our daily life. So we should find a way to solve this problem. Water is important resources. In our daily life, we often leave the tap on after cleaning hands. Sometimes we often drop litter in the river. So the water was polluted by us. I think we could use a bottle of water two or three times. We have to turn off the tap after cleaning hands.

Lets try to form a good habit and save things around us. Lets do it from now on!

Water is very important to us. We cant live without water. But the drinking water is less and less. Because we waste a lot of water in our daily life. And some of us often throw rubbish into the rivers. So the rivers are polluted seriously.

Its our duty to save water, we must do something to save water. For example, we shouldnt pour waste water into the rivers and we should pick up litter around us.

If we dont save water, the last drop of water will be our tear.

Fish cant live without water. Plants cant live without water. People cant live without water, either. As you can see, the water is very important to us. But now drinking water is less and less. The water was polluted seriously.

So we would act quickly in order to save the water, But what must we do now? I think we can plant trees, clean the banks of the river, water the plants by using used water. Turn off the shower while we are washing hair. And we shouldnt drop litter into the river and so on.

Its our duty to try our best to protect and save water. And dont forget that if we dont save water, the last drop of water will be our tear.;

Water is very important for people, animals and plants. Water is needed to many things in daily life, like taking a shower, drinking, washing clothes, making meals and so on. We cant live without water. But now water has become less and less because people waste water and pollute water. If we continue to do things like this, we shall destroy ourselves. So we should take action to improve the environment quickly. We shouldnt throw rubbish into the rivers. We should pay attention to environmental protection. We can use less water when we wash something. In a word, we should save water.

Take action quickly, there will be hope!

Water is very important. Without water, there can be no life on earth. People and animals need water. We need it to drink, to clean ourselves and to cook. What we need is fresh water, but most of the water on earth is sea water. The drinking water is becoming less and less because water was polluted by people. What should we do? I think we should save water. For example, when we brush our teeth, we should turf off the tap. We shouldnt pollute the fresh water. If we dont save water, the last drop of water will be our tear. If we continue to pollute water, we will live in a thirsty world.

Pollution is becoming more and more serious all over the world. The factory eject the dirty water, as a result , the water has becoming polluted and many fish species are dying out. We cant live without water. The earth is our only home and we should make it comfortable for ourselves. We should save water in our daily life. For instance, turn off the shower while you are washing your hair. We should recycle water. Dont let our tear become the last drop of water!

The most serious problem in the world is pollution. Water is the source of life. We cant live without water. But now some of the drinking water has become polluted and is diminishing. Something must be done to stop the pollution. Its our duty to save water. We should stop factories from pouring waste water into the river. We should plant trees in order to keep soil. If we dont save water, the last drop of water will be our tear.

The most important question in the world is pollution, but we know water, like air is very important to living things because all animals and plants need water. We, like fish cant live without water. We need it to drink, cook, and clean ourselves. We need clean fresh water, but we are polluting the lakes and rivers. Our drinking water is becoming less and less. If we continue to do things like this, we shall destroy ourselves.

I think we should follow the rules. Dont throw food away. We try to make a good habit. I know its our duty to save water. So we should save water and protect eh environment.

Now water pollution is the most serious problem. We cant live without water. Water is life. So I think we should do something go save and protect water.

Environmental protection, there are many problems at present. The most serious problems is the serious pollution of air, water and soil. Air pollution is very harmful to human health. Polluted water causes pain, resulting in death. Whats more, with the rapid expansion of modern society, vegetation greatly reduced.

In order to protect the environment, governments have done a lot of work. Adopted legislative measures to control air pollution, to protect forest resources and Marine resources and to stop any environmental pollution. Therefore, in todays government plays a most important role in environmental protection.

My view is that, in order to protect the environment, the government should take more concrete measures. First of all, should by the methods of education make people fully realize the importance of environmental protection. Second, should be more efforts to put the family planning policy into practice, because more people means severe pollution. Finally, to severely punish those who intentionally damage the environment. That they damage the environment is the destruction of man himself.

目前环保还存在着许多问题。最严重的问题就是空气、水和土壤的严重污染。污染的空气对人类的健康十分有害。污染的水引起疼病,造成死亡。更有甚者,随着现代社会的迅速扩建,植被大大的减少。

为了保护环境,各国政府做了大量的工作。采用了立法措施控制大气污染,保护森林资源和海洋资源,制止任何环境污染。因此,在当今的环保中政府起着最重要的作用。

我的看法是,为了保护环境,政府应当采取更具体的措施。首先,应当通过教育的方法使人们充分謒到环境保护的重要性。第二,应更加努力把计划生育政策付诸实施,因为人口多就意味着污染严重。最后,要严惩那些故意破坏环境者。使他们破坏环境就是毁灭人类自己。

As is known to us all, the surrounding has a great impact on our study and lives. In recent years, creating a green campus has been a common and popular goal for most universities or colleges. Creating a green campus has a great influence on students because most students spend their much time in campus.

However, in my opinion, to create green campus, what we need to do is not only to plant more trees and grasses to beautify our campus’s environment but also to create an energy-efficient and resource-cycled campus. Everyone on campus should be informed to form the habit of using resources properly and saving energy. In addition, the institutions should encourage students to use resources circularly.

In a word, creating a green campus needs us to make joint efforts. And we can achieve it by doing pieces of small matters in daily life, such as turning off the light when leaving.
