常州市区空气 PM 2．5污染分布和气象因素影响初探

摘要

PM2.5 as an important indicator of air pollutants.Its state and composition is very complex, affecting the health of the human body.According to pollutant and meteorological monitoring data from Changzhou automatic ambient air monitoring sta-tion, this paper analyzed the relationship between PM2.5 pollution and meteorological factors to provide a reference for PM2.5 moni-toring, early warning, and pollution prevention.%PM2．5作为一种重要的空气污染物指标，其形态与组成非常复杂，影响人类身体健康。本文根据常州市环境空气自动监测站系统的常年污染物和气象监测资料，研究了常州市PM2．5污染状况及与其他城市的比较，指出PM2．5的冬春季污染较重、夏秋季污染较轻的季节变化特征，日变化的双峰结构特征，以及城市风场和降水对常州市PM2．5浓度的影响规律。研究揭示PM2．5污染与气象因素之间的相关关系，为本地PM2．5监测、预警和污染防治提供参考。
