昆明市空气污染特征及成因研究

昆明市空气污染以总悬浮颗粒物污染特征，秋冬季较春夏为重，城中心郊区为重，城西和城北较城东和城南为重，除背景测点外，ＴＳＰ和ＳＯ２两种污染物均有的相关性；在目前的采样高度上，工业源对各测点ＮＯｘ浓度影响不明显。

Research on Features and Reasons of Air pollution in Kunming

Featured by the pollution of TSP,the air pollution in Kunming is much more severe in Autumn and Winter than in Spring and Summer,in downtown area than in the countryside,and in the west and north of the city than in the east and the south.Besides the background sampling sites,two major pollutants,TSP and SO 2,is correlated to different extends at other sites.The industrial source emission does not have much influence on the NOx concentration at all sampling sites at present sampling elevation.
