| 摘 要： | 介绍了模拟污染水体中各类指标的单回归，逐步聚类分析，主成份分析及逐步判别分析，在聚类图和判虽函数中，溶解氧与色度具有最紧密关系，水中总和氮氮对水质也有显影响。对模拟试验样品，主成份分类与判别分析分类的结果相类似，而对城市河流体品用判别函数别的结果与观察到的天然状态相一致。

| Abstract: | The linear regression,hierarchical clustering,principal components and stepwise discriminant analysis of the parameters for polluted aquatic ecosystem in simulated tests are presented.The DO is closely related to CH in hiera-rchical clustering graph and in discriminant functions.Total phosphorous and ammonia nitrogen in water also have remarkable effects on water quali-ty.The results of the classification for the samples by principal components analysis are similar to those by stepwise discriminant analysis.For the sam-ples collected from urban river of Tianjin,the results of the discrimination were the same as those observed. |
