农村环境质量区划的多元分析

Multivariate analysis for rural environmental qualily regional-ization.

本文提出了适合于农村环境质量区划的分区方法，即首先以主成分分析法分析农村环境质量问题，然后以多种聚类分析法取得一个初始分区系统，最后用判别分析法判别该初始分区系统中各区域单元的类型归属是否正确，对一些类型归属不恰当的作适当调整，最终得到农村环境质量分区系统。文章最后讨论了类型划分问题。

Classification methods suitable for rural envi-ronmental quality regionalization is presented in this paper:first,princlpal components analysis is used in the analysis ofrural environmental quality: then, cluster analyses are em-ployed to produce an initial zones system; finally,discriminantfunction anslysis is applied in identifying the initial zones sys-tem;some units that belong to inappropriate zones are adjust-ed, and the ultimate zones system is obtained. Problems con-cerning the formation of initial zones system are discussed onthe last part of this paper.
