Health impact assessment of the cooling benefits of urban green infrastructure from the resilience perspective

In order to address the difficulty of quantifying the cooling benefits of urban green infrastructure as health benefits and the lack of comprehensive resilience evaluation, this paper develops a systematic evaluation framework that integrates environmental and health data.Firstly, this paper retrieves urban surface temperature from land satellite remote sensing images; secondly, uses the ENVI met model calibrated with local parameters to simulate the cooling intensity and spatial range of different types of green spaces on typical heat wave days; then, combines population distribution with exposure response relationships established based on local epidemiological data, adds the Social Vulnerability Index (SVI); and finally conducts Multi Criteria Decision Analysis (MCDA).The research results indicate that the Gini coefficient of high-risk and highly vulnerable populations decreases from 0.68 to 0.52, and the coverage rate of high-risk communities increases to 78.3%.
