灾害避难所选址规划的实证研究—以山东省荣成市为例

Empirical Study on Location-allocation Optimization of Disaster Shelters: A Case Study of Shandong Rongcheng

  • 摘要: 以最小化总避难距离为目标,构建适用于地震和台风灾害的避难所P-中位选址优化模型,采用启发式算法进行解算,对不同人口情景下避难所的人口配置缺口进行分析,并以山东省荣成市为例开展了实证研究。结果表明:从仅启用地震型、仅启用台风型到同时启用全部避难所3种情景下,被选中的避难所分别为61个、125个、158个,单个避难所平均服务居民点个数分别为15.79个、7.70个、6.09个,居民点的平均避难距离分别为3 790.24 m、2 905.34 m、2 300.02 m;荣成市避难所空间分布极度不均,人口配置缺口较大的区域主要集中在北部和南部地区。据此提出近期和远期规划建设目标,可为荣成市避难所选址规划提供一定的决策依据。

     

    Abstract: With the goal of minimizing the total evacuation distance, this article develops a P-median model suitable for the location-allocation optimization of earthquake and typhoon disasters. An heuristic algorithm was applied to derive solutions. Moreover, the population configuration gap for each shelter was calculated in different scenarios. An empirical study was carried out in Rongcheng of Shandong Province as an example. The results show that: From only using earthquake type, only using typhoon type to using all shelters at the same time, 61, 125 and 158 shelters were selected respectively. The average number of residential sites served by a single shelter was 15.79, 7.70 and 6.09, respectively. The average distance of shelter was 3 790.24 m, 2 905.34 m and 2 300.02 m, respectively. The spatial distribution of shelters is extremely uneven, and the areas with large population configuration gaps are mainly concentrated in the northern and southern regions. Therefore, short-term and long-term planning and construction goals are recommended which can provide a certain decision-making basis for the planning of disaster shelters in Rongcheng City.
