城市应急避难场所是在灾难发生后为灾民提供临时生活、避难的场所,是一项非常重要的公用服务设施,其空间分布合理与否对居民生命财产安全有着至关重要的影响。以河源市中心城区为例,在GIS软件分析技术的基础上,运用可达性等4种分析方法对河源市应急避难场所空间布局进行分析评价。结果显示:河源市应急避难场所空间布局相对较差,服务可达性也较差;应急避难场所服务人口配置缺口也比较大;各街道需要调整应急避难场所的空间。最后为应急避难场所的调整与优化布局提供相关建议.
Urban emergency shelters provide a temporary shelter and shelter for victims after a disaster. It is a very important public service facility and its spatial distribution is of crucial importance to the life and property safety of residents. Taking Heyuan downtown area as an example, based on GIS software analysis technology, this paper analyzes and evaluates the spatial layout of emergency shelters in Heyuan by using four kinds of analysis methods such as reachability. The results show that the spatial layout of emergency shelters in Heyuan City is relatively poor with poor service accessibility; the population gap in service provision in emergency shelters is also relatively large; and the streets need to be adjusted for space for emergency shelters. Finally, we provide relevant suggestions for the adjustment and optimization of emergency shelter.
