基于主成分分析法,以松花江肇源江段5个例行监测断面为例,对水温、pH值、溶解氧、高锰酸盐指数、生化需氧量、氨氮、石油类、化学需氧量和总磷9个水质指标进行研究。计算各断面的综合得分,根据得分越大污染越重的原则,得出该江段各断面的相对污染程度。主成分分析法较单因子评价法对同一类别的断面间比较相对污染程度具有明显的优势,是一种切实可行的水质综合评价方法。

The principal component analysis was used to assess nine indexes in five sections in ZhaoYuan of Songhuajiang river. Total score of the cross section was calculated, the greater the score the more heavy pollution according to the principle. Principal component analysis in the same category of cross section of relative degree of pollution is more obvious than the single factor evaluation method. The principal component analysis is a kind of practical water quality synthetic evaluation method.
