摘要
利用我国大陆地区1954—2005年成灾地震事件的数据和资料,运用多元统计分析方法,研究和分析了地震灾害的分类和分级问题,找出了地震灾害的3个基本结构,提出了主成分提取-最大正交旋转-因子分析(FAPE)分类模型和欧氏平方距离-离差平方和法-系统聚类(HCWS)分级模型.运用该模型将地震灾害分为8种类型和5个等级,比较合理地解释了已有地震灾害现象.
Based on data of mainland, the classification multivariate statistical analy earthquake disaster events during 1954--2005 in the Chinese and gradation of earthquake disasters have been studied by sis. Three fundamental structures of earthquake disasters have been found and an FAPE （factor analysis-principal component-equamax rotation） classification model and an HCWS （hierarchical cluster-ward method-seuclid） gradation model have been constructed. Earthquake disasters are divided into 8 classes and 5 grades respectively in the models, which give a reasonable explanation to the phenomenon of earthquake disasters.
