摘要: 目的 分析合肥市区不同区域2012-2014年空气污染状况,为城市规划者和居民出行提供污染控制建议。方法 利用合肥市环境保护局网站数据库中主要空气污染指标的相关数据,应用SPSS 16.0软件进行统计分析。描述2012-2014年合肥市区不同区域空气质量指数的时空分布特征,分析合肥市区不同区域空气环境污染的现状及其可能的原因。结果 2012-2014年间,合肥市空气污染状况在平均水平上呈现先增长后减少的趋势。在此期间合肥市区三里街子站、长江中路、庐阳区子站、瑶海区子站以及包河区子站的空气质量指数平均值均高于全市平均水平,并且冬季是合肥市区空气污染最严重的季节。结论 合肥市区空气污染状况与地理区域和季节变化有关。Abstract: Objective To analyze the air pollution situation in different areas of Hefei, China from 2012 to 2014, so as to provide suggestions of air pollution prevention for the city planning and the residents traveling. Methods This study described the temporal-spatial distribution characteristics of air quality index (AQI) in different regions of Hefei from 2012 to 2014, and analyzed the present situation and the possible causes of air pollution.The primary data for AQI were collected from the web database of Hefei's Environmental Protection Agency. And the results were analyzed with the software SPSS 16.0. Results From 2012 to 2014, the average of AQI appeared to decline after a growth. During this period, the degree of air pollution at Sanli Street, Changjiang Middle Road, Luyang district, Yaohai district and Baohe district were all higher than the average level of the whole city in Hefei. And the air pollution was heavier in winter than any other seasons in Hefei. Conclusions Air pollution in Hefei is related to both regional and seasonal changes.
