| 摘 要： | 本文采取主成分分析法，对2005～2008年松花江吉林江段水质监测数据进行分析，通过分析主要污染物（包括：高锰酸盐指数、生化需氧量、氨氮、石油类、挥发酚、六价铬）确定近年来松花江吉林江段水体主要污染物的种类仍然是以有机污染物物为主，同时存在一定无机污染物和特征污染物。分析过程中选取5个监测断面进进行分析，首先建立5个断面污染物相关系数矩阵，得出特征值，其次确定两个主成分并分析与污染物之间关系；最后利用因子得分确定5个监测断面的水质污染程度，并提出了不同断面的环境管理方法。

| Abstract: | Through adopted major components analysis, the monitoring data of water quality of Ji Lin Sector of Song Hua Jiang River from 2005 to 2008 are analyzed. The results show that main pollutants of Ji Lin Sector of Song Hua Jiang River are organic poilutants. Five monitoring sections are selected and analyzed, and pollution degrees of water quality of five sections are confirmed, and the environmental management methods of different sections are pointed out. |
