摘　　要：研究河南省2000、2005、2010、2015年4年的PM_(2.5)质量浓度和人口密度的栅格数据,计算得出PM_(2.5)暴露人口;借助全局空间自相关、热点分析等方法,在对河南省PM_(2.5)暴露人口的时空特征进行分析的基础上,使用面板数据模型探讨其影响因素.结果显示:河南省暴露人口规模表现为先增后减的变化特征,整体规模上升,空间呈现扩散和向中部移动的特征.对河南省PM_(2.5)暴露人口具有影响的指标主要为:房屋竣工面积、公路客货运总量和气温.Based on the grid data of PM_(2.5)concentration and population density in Henan Province in 2000,2005,2010 and 2015,the population exposed to PM_(2.5)is calculated.With the help of global spatial autocorrelation and hotspot analysis,and based on the analysis of the spatiotemporal characteristics of the population exposed to PM_(2.5)in Henan Province,the influencing factors are discussed by using panel data model.The results show that the scale of exposed population in Henan Province shows the characteristics of inverted"U"change,the overall scale increases,and the space presents the characteristics of diffusion and moving to the middle.The main indicators that have an effect on the population exposed to PM_(2.5)in Henan Province are temperature,completed housing area and total road passenger and freight transportation.
