范文 (One possible version)

Hello, everyone,

Now I’ll tell you something about our research project The World Food Crisis on behalf of our group. As you know, food shortages have hit many countries in the world and even caused social unrest in some areas. But who is responsible for the current world food crisis? First, annual world grains output has declined because of climate change. Then lots of farmland has been lost due to the rapid development of industry and urbanization. Besides, faced with the rising energy prices, people have turned to the production of biofuels, which has worsened the severe situation.

Then what should we do to deal with the problem? On one hand, we should focus on the environmental protection and improve the ecology. On the other hand, strict measures should be taken to protect farmland. Of course, to build a harmonious world the developed countries should take their responsibilities to help the poor ones experiencing food shortage.

As for me, I will call on the people around me to live thriftily. And for the moment, I think, we should study hard to develop science and help solve the food shortage in the future.

Too many cars have caused a lot of serious problems in our world. Besides congestion, accidents and fast fuel consumption, cars are responsible for a good part of air pollution in big cities. One possible solution is to design and develop clean cars and clean fuels. In Shanghai, some of the public buses begin to run on natural gas, which does not give off as much carbon dioxide as petrol. Another solution is to develop modern public transportation systems and restrict the use of private cars. If the price of petrol rises constantly and the public vehicles are efficient and convenient enough, most people will not buy private cars. Thus, the total number of cars in big cities will reduce greatly. On the whole, the elimination of air pollution needs the collective efforts from the government, the public and the environmentalists.

篇14: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。

White pollution persists

WEVE been hearing and talking about it for a fairly long time: curbing what has become known as “white" pollution. But still we are using the white polystyrene (PS) foam food containers and other disposable plastic products, which largely make up this form of littering.

Miandianwang, a well-known local fast-food chain, is still handing out takeout food in these PS foam containers, even though they should been phased out before December 31, 2000, under a Central Government decree. One of the waiters said in its outlet on Hongli Road on Monday that they are going to switch to environmentally friendly containers “some time in the future".

However, the Miandianwang outlet in Sams Club, which is affiliated with Wal-Mart, is offering take-out food in light brown containers which are biodegradable. Liang, a clerk with Sams Club, told Shenzhen Daily yesterday that the club required the Miandianwang outlet to do so in its contract.

According to Liang, all the departments in the club switched to biodegradable containers during the Spring Festival holiday.

Zhao Hua, with the energy division of the Shenzhen Municipal Economic Development Bureau, one of the five municipal government departments involved in the curbing of white pollution in the city, said on Monday that large companies and retailers like Wal-Mart and Vanguard have responded to the decree by switching to biodegradable containers. But she admitted that is just the tip of the iceberg in the seemingly endless war on white pollution in the city.

Zhaos bureau has met with four other relevant departments on several occasions. What they produced is not a feasible solution but an echo or rewording of the Central Government decree, according to Luo Wei from Shenzhen Municipal Legal Affairs Bureau, who is responsible for reviewing this “echo". The ”echo" has now been passed on to the municipal government which is expected to announce it formally in the near future. But Luo said shes not sure if this rewording can play a significant role in eliminating white pollution in the city. “We dont lack laws, regulations or decrees. The real concern is the effective enforcement of these laws or regulations," said Luo.

Zhao Hua admitted that cities like Shanghai and other coastal cities which are sensitive about their image as tourist destinations are doing a better job in this regard. “Shanghai is said to have produced a very detailed handbook on how to carry out the curbing work and Hainan has even banned disposable foam slippers in hotels," Zhao said.

Liu Guanqing, president of Shenzhen Xunbao Investment Development Co Ltd, a local manufacturer of biodegradable food containers was very eager to hear the municipal governments decision on the matter. “Since early this year, Ive seen orders fly in. Ill expand production once the government announces its stance on the issue."

More than half of Beijings adult single children dont intend to have two kids, even though national policy allows them to do so.

The countrys family planning policy of the late 1970s restricted urban families from having more than one child to control population growth.

However, a new survey by the Beijing Administrative Institute shows 52 percent of those now-grown-up single children, who are allowed two offspring, do not want a second child.

Many cited economic pressures as a factor.

The results were released on Sunday at the Beijing Forum, organized by Peking University.

Beijing has roughly 2 million only-child adults.

More than 1,100 people from only-child families, aging 20 to 34, were polled.

Only 24 percent of respondents said they would like to have two children.

More than a quarter of respondents would opt for a "DINK" (double income, no kids) lifestyle.

Survey figures showed that respondents with a primary education wanted 1.1 children on average, those with a bachelor degree wanted 1.3, and those with masters or higher degrees wanted 1.5 children.

"Beijing has maintained a super low birth rate - less than 1.3 children in a family in average - for nearly 20 years, posing increasing pressure on the countrys aging population," Hou Yafei, a professor with the institute, said.

Hou said that the top four factors that determined peoples intentions to have children were "income, child care, housing and policy conditions".

"The government should encourage couples from one-child families to have a second child and should provide better welfare services."

This would promote population sustainability, Hou said.

The survey also found that people with higher education backgrounds intend to have more children because they are more confident with their financial security.

With more and more cars coming into our families, we are happy that it has greatly improved our life. But unluckily, it has also brought many problems, such as heavy traffic and traffic accidents.

Traffic safety is everybodys business. We must obey the rules. For example, we must walk on walk side, when we cross zebra – crossing, stop and look right and left, then go across fast. Don’t play football on the road .we can tell our parents not to drink before they drive, not to run through red lights, not to talk and laugh while driving etc.

We can say cars are coming into our life, but only when everybody thinks traffic safety is everybodys business can we be safe driving on roads and walking on sidewalks.

The two charts show that the increase in the U.S. population has been accompanied by a corresponding decline in the number of wildlife species. Far too many species have been lost already. This poses a danger to ecological balance.

As the human population expands, more and more wild animals are hunted for food, or because they are thought to present a threat to man. But studies show that one of the primary causes of the disappearance of wildlife is pollution, which is one of the consequences of population growth and economic development. This makes us wonder if man is able to share this planet in harmony with other life forms.

In my opinion, it is imperative to take steps to reverse the disturbing trend illustrated in the charts. One measure would be to forbid the building of cities in areas where wild life is threatened with extinction. But, more imporantly, man must learn to stop polluting the environment, or he himself will become extinct.
