基于聚类分析的我国火灾空间分布研究

Research on the spatial distribution of fire in China based on cluster analysis

为了解我国火灾事故的空间分布情况,使用系统聚类分析了我国1996-2010年的火灾统计数据,并结合地理信息系统把分类的结果呈现在相应的区域上进行火灾的空间分布特征研究。聚类分析结果将我国31个省市自治区的火灾事故分为5类,对聚类的结果使用方差分析,类与类之间存在显著差异,说明通过系统聚类得到的分类结果是科学的。进一步分析显示我国火灾事故在空间分布上存在一定的规律性。分析结果可以对了解我国火灾分布特点以及为相关部门提供决策支持。

In order to know the spatial distribution of fire accident in China,the hierarchical clustering analysis was used to analysis the fire statistics data from 1996 to 2010.Also the ArcGIS software was used to show the Clustering results on the Chinese map and conduct the space research.The results demonstrated that the fire situations of 31 provinces were divided into 5 groups.The characters were similar within a group and different between groups by tested with ANOVA.Further analysis showed that there were some rules in the spatial distribution of fires.The results would help know the distribution of the fire as well as provide decision support for some relevant departments.
