1、关于雾霾的论文 篇一：关于雾霾的 课 程 论 文 标题： Of Haze 学生姓名陈艳梅指导老师 夏丽云 二级学院 外国语学院 专 业英语 班 级 11 英语（1）班 学 号1111101002 课程名称 美英报刊选读得分 2014 年 5 月10日 Of Haze _ A Bachelors Thesis Presented to The School of Foreign Languages Jinling Institute of Technology _ In Partial Fulfillment Of the Requirements for the Reading Course

2、in News Publications _ by Chen Yanmei May 10, 2014 Abstract It has been years since we paid attention to protecting the environment, however, the environment gets more and more serious rather than better. In the film Private Custom , we make apologies to the sun, for we cant see it clearly because o

3、f the haze; we make apologies to polluted river- the mother who nurtures us, for it is stink because of contamination and it may be unwilling to continue to nurture us; we make apologies to the soil, for we are so greedy of extraction of oil that the soil is infertile“PM2.5”and “Haze” have already b

4、een familiar to us, especially in Beijing and Nanjing. Living in Nanjing, I experienced the haze and had a deep thought about it. So, making use of the opportunity, I will talk it through. Key Words : Haze; Nanjing; harm; reason; solutions1. Introduction The longest distance in the world is that I c

5、ouldnt see Chairman Mao even though I am right in front of the Tiananmen! Nowadays,“PM2.5”and “Haze” have already been familiar to us, especially in Beijing and Nanjing. One of the most popular iPad apps in Beijing at present is China Air Pollution Index. The app is both addictive and disturbing. I

6、checked the numbers and discovered that the AQ level, which measures fine particulates that are especially dangerous, was 250 about five times the level deemed safe. Living in Nanjing, I experienced the haze. At that time, all the middle school students had two days off to keep away from the haze. H

7、owever, we university students had classes as usual. Maybe we are stronger than middle school students, but even they are kept indoors, it is hard to escape from the harm of haze. So, lets talk about haze in the following aspect. The definition of haze WHO guidelines say average concentrations of th

8、e tiniest pollution particles - called PM2.5 - should be no more than 25 microgrammes per cubic metre. Air is unhealthy above 100 microgrammes and at 300, all children and elderly people should remain indoors. With the deterioration of air quality, haze got worse and worse. Many areas incorporated h

9、aze into the fog together as weather warning forecasting. In fact, there is a big difference between fog and haze in some ways. For example: fog occurs when the air is humid, while haze occurs when the air is relatively dry, the relative air humidity is usually below 60%. Its formation is due to a l

10、arge number of very fine uniform floating dust particles, soot, salt, etc. in the air, causing the effective horizontal visibility less than 10KM air turbidity. Diurnal variation haze obscured. When there is no large change in the air mass, haze lasts for a long time, sometimes over more than 10 day

11、s. Because the haze, mist, dust storms, blowing sand, dust, smoke and other weather phenomena are caused by floating in the air and a lot of very fine dust or smoke particles , etc. resulting in effective horizontal visibility is less than 10KM. So sometimes it is difficult for weather professionals

12、 to distinguish them. In order to draw the right conclusions, weather professionals must combined the weather background, sky conditions, air humidity, odor and color satellite monitoring and other factors to make a comprehensive analysis, but sometimes fog and haze can interchange . The harm of haz

13、e The haze will affect not only health of people but also the economic, as well as the future of China. First, once inhaled, the tiny particles can make people more vulnerable to respiratory infections, as well as leading to increased mortality from lung cancer and heart disease. We all know that lo

14、sing a family member is how sorrowful, so haze may destroy not only a person, butalso a family. Second, a number of foreigners wont go to China for travelling because of haze, which will bring a loss to our economic. Third, the decline of economic will in turn weaken national power. After all, econo

15、mic decides politics and culture. In this way, it will be difficult for us to make China Dream come true. Fog and haze are killer for patients with cardiovascular disease, especially for those who with respiratory and cardiovascular diseases, the elderly. They had better not go out, nor do morning e

16、xercises, otherwise, it may induce the disease, or a heart attack, even causing life-threatening. Experts point out that the reason why fog and haze are dangerous days for patients with cardiovascular disease is that the air pressure is low, oxygen decreases in the air when there is haze, so its eas

17、y to feel tightness in chest. The wet morning mist is cold, which can easily lead to fluctuations in blood pressure, vascular spasm, cardiac load and so on. Meanwhile, some pathogens can cause headaches fog, and even induce high blood pressure, stroke and other diseases. Therefore, to avoid danger,

18、people with cardiovascular disease, especially the elderly and infirm, should not go out or do morning exercise in the haze day. In one word, haze is harmful to everyone and everything. And the harm can be direct or indirect, so it is difficult for us to escape from it. Realizing the harm, we ought

19、to find out the reasons and take relative steps to prevent it. The reasons for haze Pollution in China is now so bad that it threatens to obscure the vision being laid out by Xi Jinping, the new president. Mr. Xi has popularised the idea of a Chinese dream, an obvious foil to the American dream. His

20、 dream seems to involve increasing wealth at home and increasing power abroad. But the choking smog suggests that the leadership needs to rethink its national goals. After all, what is the point of rapid economic growth if it creates cities in which it is dangerous to breathe? One study, published i

21、n The Lancet medical journal last year, suggested that air pollution might have caused about 1.2m premature deaths in China in 2010 alone a considerable figure even for a country of 1.3bn people. Beijing has registered a 60 per cent rise in lung cancer cases in the past decade. With pollution that b

22、ad, otherwise innocent sights take on a sinister aspect. Ma Jun, a prominent environmental activist, says that on days when the smog envelops the city he winces when he sees children playing football outdoors. Indeed many schools, foreign and Chinese, now forbid kids from playing outside on bad days

23、. The pollution in Beijing is also an international embarrassment. The government went to great lengths to show the city off at its best during the 2008 Olympics, yet now the first thing any foreign visitor wants to talk about is the pollution, and many expats talk about leaving. Even allowing for t

24、he installation of air filters in official residences, Chinas leaders have to breathe the same air as their citizens. So one might expect them to make pollution their top priority. But the signs are that rapid growth remains goal number one. That is partly because, in recent decades, the government

25、has derived its legitimacy from growth. Officials speak with justifiable pride about the hundreds of millions of people who have篇二：关于雾霾的论文 关于雾霾的论文 雾是气温低于露点时，近地面空气中水汽凝聚而构成的，假设雾升高离开地面就变成了云。它是一种由大量水滴或冰晶微粒组成的乳白色的悬浮体系，空气相对湿度接近100%，在工厂附近等悬浮颗粒物浓度较大的地点，那么会呈现出土黄灰色。雾的产生会使空气的水平能见度降低，据此又能够区分为轻雾、雾、大雾和浓雾。轻雾通常在早晚产

26、生，水平能见度在110公里；雾的能见度在0.51公里；大雾的能见度在100500米；浓雾时能见度小于100米。 霭在汉字字典中的解释是云气和轻雾，在气象学中那么指的是气体中悬浮有微小水滴的现象，当霭出现时，水平能见度一般比雾出现的时候要高，通常在10公里以上。由于目前城市空气中悬浮颗粒物较多，提供了大量的水汽凝聚核，因此霭出现的也较多，据报道，深圳市一年当中有100多天都出现了霭这种天气现象。但是霭是一个不大严格的概念，因此在气象学中较少用到。 霾这个字在史书中是用来表示有风沙的天气的，有“风而雨土为霾”之说。在气象学中霾是一种天气现象，是指大量极细微的干尘粒均匀的浮游在空中，使水平能见度小于

27、10公里的空气普遍混浊现象，霾使远处光亮物体微带黄、红色，使黑暗物体微带蓝色，当水汽凝聚加剧、空气湿度增大时，霾就会转化为雾。霾的构成与污染物的排放亲切相关，城市中机动车尾气以及其它烟尘排放源排出粒径在微米级的细小颗粒物，停留在大气中，当逆温、静风等不利于扩散的天气出现时，就构成霾。篇三：关于雾霾的论文3000字 关于雾霾3000字 全国20个省份空气到达重污染，东部城市大多数未能幸免，面对网友们的质疑和提征询，我以为当前最重要的征询题是如何对待雾霾征询题？ 首先要正确剖析雾霾导致的环境征询题，应该用历史的观点来看。中国的经济高速开展已经持续了30多年，改革开放前，生活仍旧窘迫的中国人渴望实现

28、小康的生活，渴望活在“楼上楼下电灯”的环境里。为了这个目的大范围、大力度的经济改革推进了中国经济的大开展，在以往的30多年里，中国经济出现了宏大的飞跃，这个飞跃实现了众多中国人的富有梦，我们的物质生活出现的丰富场面导致了我们对资源的过度开发。那个时候，我们中国人最大的梦想确实是富有！ 现在当环境出现征询题的时候，我们才觉察我们的梦想是需要不断调整的，正如以往中国人希望国家富有百姓有钱，现在中国人希望国家强大，百姓生活质量提高，也确实是说当前中国人的富有梦逐步被更为完善更为现实更为理想的中国梦所替代。中国梦的实现又把所有的中国人推向一个接着改革的大潮中，以往我们追求消费力，追求GDP，今后我们追

29、求和谐，追求人与自然和谐开展、追求人与人的和谐相处、追求国与国的和谐共赢，因此我们要珍爱环境，我们要和平崛起，我们要实现伟大的民族复兴。 我们都成了新时代的改革者，都成了新时代的追梦人，为了今后改革的成功，我们又需要深化的考量，而摆在我们面前最紧要最现实的征询题可能确实是雾霾和环境征询题，雾霾为什么会出现，为什么会这么严峻，今后我们又如何开展？雾霾与环境征询题我们尽管不能看成是开展的弯路，但是即便是错误我们也要平复面对，当前最应该做的不是抱怨，而是从每个人本身的一言一行做起，少开车多走路，少浪费多节约等等，每个人都做对环境有利的事情，那么我们天蓝水清，空气清新的梦想一定会实现。 2013年1月

30、份以来，全国中东部地区堕入严峻的雾霾和污染天中，中央气象台将大雾蓝色预警晋级至黄色预警。从东北到西北，从华北到中部导致黄淮、江南地区，都出现了大范围的重度和严峻污染。 这种现象值得我们高度注重。 雾霾天气的出现严峻污染了空气，阻碍了交通，同时会引发呼吸道感染和心脑血管疾病，严峻阻碍了人的生命健康。而有的政府推脱责任说是周边城市污染严峻导致的，城市污染确实是雾霾构成的一种缘故，但是作为治理国家公共事物的政府而言，更多的应该是看到污染带来的危害已经如何处理这一征询题，而不是推脱责任。尽管是极个别的政府出现这种现象，但也会严峻阻碍政府的执政力和公信力，不利于雾霾天气的良性处理。 产生雾霾天气的缘故是

31、多方面的：一方面与我国冬季的气压、空气湿度有亲切关系。由气压低、空气不流淌、空气湿度低、地面灰尘大造成了雾霾天气久置不散。另一方面汽车尾气、工业燃料排放、冬季取暖等是污染物的主要来源。除此之外，相关部门对污染征询题的不作为也是雾霾天气的缘故之一。 对此，处理雾霾天气需要各方努力。 首先，建立重污染日应急，便于市民应对污染的天气。尽量防止有呼吸道疾病和心脑血管疾病的人群减少晨练次数，减少室外活动时间，减少开窗，外出时间较长要戴好口罩。留意出行平安，降低车速、平安驾驶。 其次，制定相关的排放标准，健全环境污染防治相关法律。北京市已经针对工业污染、扬尘污染、燃煤污染等出台了相关的治理标准，同时规定的

32、相对应的应对措施。从而使大气污染的预防和治理有法可依。相对应地，相关法律确立之后要监视其落实到位，加大违法的本钱和打击力度，从而降低污染率。 再次，相关部门加强征询责，建立区域联防联控机制 。李克强总理在谈空气治理时提到：我们必须有所作为。这也要求我们作为政府部门要加强环境污染的权责划分，明确各个工作人员的职责，杜绝环境保护等相关部门形同虚设的情况。遇到征询题、正视征询题、处理征询题，从而使环保标准得到实在有效地落实。 最后，加快转变开展方式的转变。将经济开展由粗放型向集约型开展，进一步地开展绿色经济、开发环境友好型能源。克服唯GDP论以及先污染后治理的开展方式。坚持资源节约和环境友好的可持续地的经济开展方式。 相信通过各方努力。类似雾霾等空气污染征询题会得到实在、有效地处理。
