摘 要:通过对典型大气污染类型区进行实地监测 ,采用统计分析和污染指数的方法 ,研究了平顶山市矸石山和市区典型大气污染的现状 ,探讨了大气污染和绿化指标之间的关系 .结果表明 ,监测区大气污染较为严重 ,各类型区之间污染水平具有显著性差异 ;大气污染与绿化覆盖率相关密切 .林木覆盖率在空气净化中有重要作用 .By means of statistical analysis of the pollution index, the current conditions of typical air pollution in the mining area and urban area in Pingdingshan city were studied besed on the on the spot monitoring of air pollution in typical areas. The relationship between air pollution and the index of afforestation were discussed .The results showed that the current air in the monitored areas is severe pollution . The seriousness of pollution varies in different areas. The air pollution and ratio of afforestation are closely correlated to each other. It is obvious that afforestation is the main contributors to the purification of air.
