Study on environmental exposure risk assessment of Nanjing residents from the perspective of equity
The level and equity of urban environmental exposure are of great significance to the construction of healthy and liveable cities.This study measures the environmental exposure levels of high temperature,air pollution,and green spaces in Nanjing in 2022,and uses bivariate spatial autocorrelation analysis to explore the correlation between different environmental exposures,and analyzes their correlation with three socio-economic indicators:aging rate,housing price,and GDP,in order to study the fairness of environmental exposure in Nanjing.Research has found that the environmental exposure levels in Nanjing exhibit significant spatial heterogeneity,with heat exposure being more similar to the exposure of three air pollutants,and also showing varying degrees of positive correlation with three socio-economic indicators;The distribution pattern of urban green space exposure levels is different from the other two types of exposure,and it shows a certain inhibitory effect on it,and only shows a certain negative correlation with housing prices.Research can provide reference for the planning and management of urban green spaces and the formulation of strategies for environmental hazards.
