Space zoning of urban emergency shelters based on GIS:taking main urban area of Chengdu as example
In order to improve the overall service capacity of urban emergency sheltering after disaster,on the basis of com-prehensively considering the population distribution,transportation network,service capacity,construction cost,road network accessibility and other factors,the GIS spatial analysis technology was used to carry out the research on emergency sheltering space zoning in the main urban area of Chengdu,Sichuan Province.An efficient,fair and economic space zoning scheme of emergency shelters was put forward,and a set of scientific scheme formulation methods and processes was formed.The results show that in order to improve the overall emergency sheltering service capacity in the main urban area of Chengdu,it is neces-sary to expand the capacity of Experimental Foreign Language School and Lido Park,and upgrade the transportation facilities around Huanhuaxi Park.The main urban area of Chengdu can be divided into 10 emergency sheltering zones,and 14 optimal shelters can be determined to meet the emergency sheltering needs in the area.The results can provide technical support for the planning and decision-making implementation of urban population transfer,sheltering and resettlement.
