行为暴露视角下高温健康风险评估
Heat Health Risk Assessment from the Perspective of Behavioural Exposure:A Case Study of Nanjing City
摘要
Abstract
Extreme heat in the context of climate change poses a great challenge to population health,and since heat health risks are not spatially homogeneous,heat health risk assessment is an important way to effectively identify high-risk areas and implement differentiated guidelines for spatial planning.Walk score is used to measure the likelihood of people being exposed to outdoor heat and a heat health risk assessment system is constructed accordingly.Taking the main urban area of Nanjing as an example,the spatial distribution characteristics of heat health risk are quantitatively evaluated from a refined scale,and high-risk areas and dominant risk factors are precisely identified.The results show that:①The overall spatial structure of walk score in the main urban area of Nanjing is"high inside and low outside,multi-core spatial",and the areas with high walk score have higher heat health risk.②There are obvious heterogeneity in the spatial distribution of heat hazard,exposure,sensitivity and adaptive capacity.High-hazard areas are concentrated in high-density built-up areas and industrial land.The central areas of city are characterized by"high exposure,high sensitivity and high adaptabil-ity"and the peripheral areas are characterized by"low exposure,low sensitivity and low adaptability".③The spatial lay-out of the high-risk areas reflects the circles:the central area is dominated by high exposure,the transition area is dominat-ed by synthesis,and the peripheral area is dominated by low adaptive capacity.This study proposes short-term resilience enhancement pathways and long-term resilience enhancement pathways based on dominant risk factors,in order to provide references for reducing urban heat health risk.关键词
