摘要
应用系统聚类分析方法(HCA,Hierarchical Cluster Analysis)和主成分分析方法(PCA,Principal ComponentAnalysis)有机结合而成的HCA-PCA法对南京市雨花台区板桥河流域的环境污染现状进行分析,将区域水环境质量按月份污染轻重进行分类,确定了污染较重的月份是4月、6月和10月,再进一步明确该区域污染因子为石油类,并提出相应的水环境管理建议。
HCA-PCA method which combines HCA （hierarchical cluster analysis） with PCA （principal component analysis） is applied to a comprehensive evaluation of water environment quality of the Banqiao River in Yuhuatai District , Nanjing City. Months are put in order according to the extent of pollution by HCA method. It shows that the months of serious pollution are April,June and October, and the most important pollution factor of thje Banqiao River is petroleum （including animal and plant oil）.
