| 摘 要： | 针对目前我国城市内河普遍遭到污染的问题，在分析影响内河水质因素的基础上，选取BOD5（五日生化需氧量）、CODcr（化学需氧量）、石油类、挥发酚、NH3-N（氨氮）、总磷等6个主要因素作为评价因子，建立了城市内河水质评价的投影寻踪分析模型，采用人工鱼群算法对评价模型进行优化，并将该模型应用于南宁市10条内河水质的评价与排序。研究表明，用投影寻踪回归分析法进行水质评价，避免了传统评价方法由于主观原因造成的误差，评价结果合理可信、方法简单，为我国城市内河水质的评价提供了新途径。

| Abstract: | Pollution is getting worse in China's urban rivers at present.In this paper,by analyzing factors affecting inland river water quality,choosing BOD5,CODcr,petroleum,volatile phenol,NH3-N and total phosphorus for evaluation factors,a water quality evaluation method is established,and the model is applied to inland rivers in Nanning.The evaluation results are accurate and some errors are eliminated because of the subjective factors of traditional methods.Projection pursuit is a new evaluation method of urban i... |
