摘　　要：结合居民日常生活范围、政府行政管理单元、避难行为与需求进行防灾分区的划定是未来趋势。首先,从出行需求、层级划分及设施配套3个方面对社区生活圈与防灾分区进行对比,梳理出符合我国规划体系的防灾分区等级划分,并明确各级防灾分区的服务规模与设施配套;其次,提出一套考虑居民防灾避难行为和避难时间,以避难场所和应急救援防灾设施的服务范围分析为基础,结合社区生活圈空间范围的防灾分区定量划定方法;最后,将该方法应用于湖南省花垣县中心城区的防灾分区划定实践,提出相关防灾设施用地的优化调整建议。研究成果可为国土空间规划综合防灾专项规划编制中的防灾分区划定提供技术和方法参考。Integrating residents'daily living space,government administrative units,and evacuation behaviors and demands into the delineation of disaster prevention zones is a future trend.Firstly,community life circles and disaster prevention zones are compared based on travel demand,hierarchical division,and facility allocation.Then disaster prevention zoning classifications that align with China's planning system is outlined,specifying the service scale and facility allocation for each level.Secondly,a quantitative method for delineating disaster prevention zones is proposed.This method considers residents'evacuation behaviors and times,analyzes the service areas of evacuation shelters and emergency rescue facilities,and integrates the spatial boundaries of community living circles.Finally,this method is applied to the central urban area of Huayuan county,Hunan province,to practice disaster prevention zoning and propose optimization adjustments for disaster prevention facilities.The research findings provide technical and methodological references for the delineation of disaster prevention zones in the preparation of comprehensive disaster prevention plans within territorial spatial planning.
