2000-2020年我国PM2.5时空特征及其影响因素
Spatio-Temporal Characteristics and Influencing Factors of PM2.5 in China from 2000 to 2020
摘要
Abstract
Based on the PM2.5 panel data from 2000 to 2020 in China,this study comprehen-sively applies kernel density estimation,spatial correlation analysis,and the spatial Durbin model to systematically analyze the spatio-temporal characteristics and influencing factors of PM2.5 pollution in China.The findings indicate that:the inter-annual evolution of PM2.5 pollution in China follows an inverted U-shaped pattern,while the quarterly and monthly evolutions follow a U-shaped pat-tern;spatially,PM2.5 pollution exhibits significant spatial clustering and spatial dependence.Addi-tionally,per capita GDP,the proportion of the secondary industry,population size,and average temperature significantly influence PM2.5 pollution in China.Factors related to natural condition have a significant spatial spillover effect on PM2.5 concentration levels.关键词
