| 摘 要： | 针对数据标准化信息丢失以及主成分中各系数相近造成的涵义不明确,对主成分分析法进行了改进,很好地实现了降维的效果.将其应用于河北省白洋淀水质综合分析,结果表明:在各观测断面中普遍存在富营养化现象,氨氮、总磷是水质的主要污染指标.通过对各断面的水质进行综合评比,得出各站点的污染程度排序,为白洋淀区域治理提供理论指导. |

| Abstract: | The principal component analysis method is improved in order to decrease information loss during data standardization,and to make components coefficients' implications more obvious when the coefficients value is similar.Then the new method is applied in water quality appraisement of Baiyangdian Lake to analyze the pollution index information,the results indicate clearly that eutrophication exists in each observation section,NH3-N and TP are major pollution factors;and based on the integrated evaluation of each observation site,their contaminative level is sorted.The analytical results provide the theory basis for controlling the water pollution in Baiyangdian Lake. |
| Keywords: | improved principal component analysis method water quality of Baiyangdian Lake eutrophication |
