摘要
为了从宏观上得到我国各地区火灾形势的异同,以为我国制定合理的消防法律法规提供参考,通过对我国大陆31个地区火灾统计数据进行预处理,利用因子分析方法将预处理数据进行降维处理,并利用聚类分析得到总体分类,分类结果表明每一类的火灾特性相对比较接近,不同类之间火灾特性差异较大。
This paper processes the data of 31 provinces in our country. And based on the data,the paper uses factorial analysis and cluster analysis methods to obtain the classification. Individuals in the same classification have similar characteristics, and individuals in different classifications have different characteristics. It is good for our country to make proper policies in view of different areas.
