Analysis of the impact factors of PM_(2.5) in Chengdu and its prevention strategies

采集了2015年全年成都市主要城区的大气监测数据,按月进行了相关统计.结合成都市人口经济、机动车尾气、工业分布及排放等实际情况,论述了空气PM_(2.5)污染来源;针对实时采集的数据,绘制了成都市气温、降雨量与PM_(2.5)数值的关系图,分析了成都市地理、气候因素对PM_(2.5)指标的影响,进一步提出了有针对性的系列防治策略与措施.

The atmospheric monitoring data of the main urban areas of Chengdu in 2015 were collected,and the monthly statis- tics was carried out based on these data.
