乌兰浩特地区大气污染成因与防治对策研究

近年来,随着乌兰浩特地区经济社会的迅速发展,空气污染日趋严重,已经影响到了经济、社会发展和市民的生活.文章阐述了大气污染对人类健康的影响,研究探讨了国内关于城市大气污染的现状,结合乌兰浩特地区大气污染的调查分析,以乌兰浩特市2008、2009、2010年大气环境质量监测数据为依据,详细研究了乌兰浩特地区大气污染的主要污染源及污染物,归纳总结特征及其变化,采用了空气污染指数（API）分析和评价了大气污染的原因.研究结果表明,乌兰浩特地区空气质量状况2009年比2008年明显好转,但PM10仍有超标现象;通过特征分析可知大气污染有逐年上升趋势,随季节变化相对明显,可吸入颗粒物、二氧化硫和二氧化氮的浓度在春冬季分别是夏秋季的0.5倍到1.5倍：采用空气污染指数（API）对乌兰浩特地区的大气污染进行评价结果表明,煤炭燃烧后的污染物是乌兰浩特市空气污染物的主要来源,同时地理环境对乌兰浩特地区空气质量有较大影响,山风产生的局地环流不利于污染物的扩散,特别是遇到静风、逆温等不利于污染物扩散的气象条件时,就会加重环境空气污染,导致污染物农度大幅度升高.造成乌兰浩特地区大气污染的原因较复杂,通过分析研究得到了主要原因是工业和能源结构不合理、冬季取暖燃煤、汽车尾气、特殊地形气候、相关政策法规不太健全及环保宣传监督工作做不到住.并针对乌兰浩特地区的实际情况提出了控制大气污染的对策措施.总之,该研究找到了乌兰浩特地区大气污染的问题,为乌兰浩特市环境污染综合治理提供了一定的参考依据.

Research on air pollution Cause and preventing and curing countermeasure in Wulanhaote

In recent years, with the rapid development of economy and society of the Wulanhaote, worsening air pollution has affected the economic and social development and resident＇s lives. Firstly, this paper describes the effect of air pollution on human health, explores the domestic situation on urban air pollution and summarizes the contents of this article and significance of the topic.Followed by atmospheric pollution survey of Wulanhaote, to Wulanhaote city 2008, 2009, 2010 monitoring of air quality data as the basis, it identifies the main source of air pollution and pollutants in Wulanhaote, summarises features and changes, uses the air Pollution Index （API） analysis and evaluation of the causes of air pollution. Research results show that 2009 year and 2008 year comparison for Wulanhaote regional air quality condition were taken improved obviously, But there are still phenomenon that the PMl0 exceeds standard. Through the analysis of characteristics of knowable atmospheric pollution have been rising trend, with the seasons change relatively obvious, PM~0and sulfur dioxide and nitrogen dioxide concentrations in spring winter respectively is a summer of 0.5 times to 1.5 times. The use of air pollution index （API） to Wulanhaote area of atmospheric pollution evaluation, the results show that the coal burning pollutant is the main source of air pollutants toWulanhaote city. Meanwhile geographical environment on Wulanhaote regional air quality has great influence on ,The mountain of local circulation produce unfavorable to the spread of pollutants. Especially meeting static wind, inversion temperature etc against pollutant dispersion meteorological conditions, it can aggravate the environmental air pollution, causing the pollutant concentration greatly elevated. Wulanhaote regional air pollution caused by the reason is relatively complex, through analysis got main reason is industry and energy structure unreasonable, winter heating coal, car tail gas, special topographical climate, relevant policies and regulations don＇ t sound and environmental publicity supervisory work to do not reach the designated position. And in the light of the actual situation of Wulanhaote region put forward the countermeasures to control air pollution.Anyhow, the study found Wulanhaote area of atmospheric pollution problems, in order to WuLanHaoTeShi environmental pollution comprehensive control provides a certain reference.
