基于主成分分析与聚类分析的水污染排放分布研究

Research on Distribution of Water Pollution Emission Based on Principal Component Analysis and Cluster Analysis

阐述了主成分分析以及聚类分析,结合spss统计分析软件,采用主成分与聚类分析的复合模型,对我国各地区废水中污染物排放量进行了主成分分析,从12个指标因子中提取出4个相互独立的主成分,并将各地区的主成分因子得分进行聚类分析,最终将31个地区分成5类,分析了各类地区的污染排放特征,提出了重点整治措施,以利于各地区污染控制与防治。

Thisarticle introduced principal component analysis and cluster analysis.Combined with SPSS statistical analysis software,the wastewaterpollutantemission from across the countrywere analyzedbased on the composite model of principal component analysis and cluster analysis.4 mutually independent principal components were extracted from 12 index factors.Then we analyzed the principal component factor scores of regionswithcluster analysis,and finally the 31 regions were divided into 5 categories.in the research,we analyzed the pollution emission characteristics of different regionsand put forward the key regulation measures,which would be conducive to the control and prevention ofregional pollution.
