| 摘 要： | 应用主分量分析法,建立一个度量湖泊富营养化程度的综合指标,根据该综合指标的大小,可以进行湖泊富营养化程度的相互比较.通过实例分析并与统计评分评价结果比较表明,该法具有显著辨别不同富营养程度的变异性能力.

| Abstract: | The principal component analysis was used to derive a comprehensive index which can be used to describe the trophic state of a lake and to compare the eutrophication degree among lakes. The procedure was applied in a case study with statistical evaluation. |
| |
| Keywords: | principal component analysis trophic state lake eutrophication. |
