基于空间聚类的应急物资储备一体化区域划分*

近年来我国各种重大的自然灾害、公共卫生事件、事故灾难、社会安全事件等非常规突发事件频发，造成了严重的人员伤亡和财产损失。一体化区域的应急物资储备是非常规突发事件应对的有效保障，一体化区域的划分即一体化应急资源布局的层次确定问题是首要问题。利用空间聚类方法来解决一体化区域的最佳层次确定，并给出相应的动态聚类算法，算例研究表明此方法给出的区域划分能够达到救援效率与储备成本的折中，具有较好的实用性。

Integration regional area division for emergency resources reserving based on spatial clustering

Various natural disasters, public health incidents, accidents disasters, social security incidents and other unconventional emergencies happened frequently in recent years, which caused serious casualties and property losses.Integration of the regional emergency resources reserving system is the effective way to emergency response.Regional area division as well as the level of the regional area is the primary issue. This paper used spatial clustering to determine the best level of the regional area and gave the corresponding dynamic clustering algorithm. Numerical cases study show that this method can get the trade-offs between rescue efficiency and reserving cost which is very practical.
