城市空气污染指数分析及其防治对策——以广西南宁市为例

Urban Air Pollution Index and Countermeasures Analysis——A Case from Nanning of Guangxi

利用统计软件对南宁市2001—2010年空气污染指数及主要污染物数据进行了分析研究,建立了回归模型。对回归模型进行分析和检验,结果表明:南宁市的空气污染主要与可吸入颗粒物密切相关,2005—2009年,可吸入颗粒物污染水平呈现下降趋势,但2010年后又有所上升。据此分析了南宁市大气环境污染成因及其危害性,并在城市环境质量监管、城市合理布局、提高城市居民的环保意识等问题上,提出相应的对策和建议,旨在为广西解决城市大气环境污染问题提供基础资料。

The air pollution index and the main pollutants from 2001 to 2010 are analyzed by statistical software.Regression model is built.According to analysis and test on regression model,the air pollutants of Nanning are mainly inhalable particles.There is a downward trendency in the pollution inhalable particles from 2005 to 2009 but an increase after 2010.The causes in air pollution of Nanning are analyzed.Corresponding countermeasures and suggestions for urban environment supervision,reasonable urban layout and urban residents environmental awareness are proposed for Guangxi to solve urban air pollution problem.
