摘要
基于主成分分析法,对磁湖13个水质指标进行了对比研究。结果表明,影响磁湖水质的主要指标为pH、电导率、水温、叶绿素、五日生化需氧量、氨氮、化学需氧量、总磷;其他指标对磁湖水质的影响较小;其中,氨氮、总磷指数代表水体引起湖泊富营养化的营养元素的污染状况,而五日生化需氧量、化学需氧量是磁湖水体中有机污染的反映。
Using principal component analysis（ PCA）,a total of 13 water quality index of Cihu Lake was comparatively studied. The results showed that main influencing indexes for water quality of Cihu Lake are pH value,conductivity,water temperature,chlorophyll,5th biochemical oxygen demand,ammonia nitrogen,chemical oxygen demand and total phosphorus; Other indicators have less effect on magnetic water quality; Among them,ammonia nitrogen,total phosphorus index on behalf of the water body of lake eutrophication pollution condition of nutrition element,5th biochemical oxygen demand and chemical oxygen demand is the reflection of organic pollution in water bodies.
