中国典型城市环境空气质量变化趋势分析研究

Analysis on Air Quality Changing Trends in Typical Cities of China

文章选取北京市、兰州市、乌鲁木齐市、青岛市、武汉市、深圳市这六个典型城市为研究对象,利用2003年-2013年六个城市的SO2、NO2和PM10浓度数据,计算出区域空气综合污染指数和污染负荷指数,并采用Daniel趋势检验法分析主要污染物的变化趋势。结果表明,六个典型城市环境空气质量状况从优至差排列依次为深圳、青岛、武汉、北京、兰州、乌鲁木齐;六个典型城市空气首要污染物为PM10,SO2的污染负荷呈下降趋势,NO2的污染负荷呈上升趋势;各城市的空气质量整体呈现好转趋势,表明大气治理初见成效。

This essay researches the atmosphere quality of Beijing, Lanzhou, Urumqi, Qingdao, Wuhan and Shenzhen. The data of atmosphere quality gazette from 2003 to 2013 are used to analyze the pollution situations and differences on the basis of comprehensive air pollution index, pollution load index, and analyze the main pollutants＇ change trend by Daniel trend of SO2 , NO2 and PMlo in these cities. The comprehensive air pollution index indicate the order of these typical urban environmental air quality is Shenzhen, Qingdao, Wuhan, Beijing, Lanzhou, Urumqi. In these typical cities, the primary pollutant is PM10, and the pollution load index of NO2 is on the increase, along with the downward trend of SO2. Urban air quality has been improving in re- cent years, pollution control in some cities air pollution has achieved some initial success. The air quality of some cities and re- gions has improved.
