摘要
随着工业化与城镇化的发展,城市大气污染问题愈发凸显,其防控治理仍是新时期我国生态文明建设的当务之急.以城市形态为切入点,基于我国288个城市2010、2015、2020三个年份的面板数据,应用静态空间滞后面板数据模型、多尺度地理加权回归模型、地理探测器等方法,探讨城市形态对大气污染的影响及其异质性.结果表明:1)从所有样本的总体建模结果来看,紧凑度指数、Boyce-Clark形状指数对PM25浓度的影响为负,分形维数的影响为正,延伸率的影响不显著;2)紧凑度指数和分形维数对PM25污染影响的地域分布异质性格局都表现为东北、华北、西南地区较高而东南、西北地区较低或不显著,Boyce-Clark形状指数则具有明显的东西分异特征;3)紧凑度指数、Boyce-Clark形状指数、分形维数对PM2.5污染影响的城市规模异质性和地理环境异质性均不显著,而延伸率表现出在平原城市中为正、山地城市中为负、滨海城市中不显著的地理环境异质性特征.
Abstract
With the development of industrialization and urbanization,concerns about the urban air pollution become increasingly prominent,and its prevention is still one of the urgent tasks for ecological progress in the new era.Based on the panel data of 288 Chinese cities for years of 2010,2015,2020,the influences of urban form on air pollution and its heterogeneity were discussed using models including Static Spatial Lag Panel Data Model,Multi-scale Geographically Weighted Regression Model and Geographical Detector.The results show that:1)the influences of Compact Ratio and Boyce-Clark Shape on PM2.5 concentration were negative,while for Fractal Dimension were positive and Elongation Ratio were insignificant,according to Static Spatial Lag Panel Data Model with all samples;2)the regional heterogeneity pattern of the influences of Compact Ratio on PM2.5 was similar to the Fractal Dimension,which showed stronger in Northeast/North/Southwest China but weaker or insignificant in Southeast/Northwest China,while the influences of Boyce-Clark Shape appeared an obvious differentiation between East China and West China;3)the heterogeneity of urban size and geography for the influences of Compact Ratio,Boyce-Clark Shape and Fractal Dimension on PM2.5 were not significant,while the influences of Elongation Ratio showed positive for plain cities,negative for mountainous cities and insignificant for coastal cities.
