| 摘 要： | 2008年8月至2009年7月研究了江苏东太湖网围养殖区、东茭咀、油车港等12个典型湖区的水环境特征,运用主成分分析法研究东太湖水质的空间异质性及主控因素.结果表明,东太湖水质在各区域存在显著差异,季节变化明显,主要表现为丰水期水质优于枯水期. 12个水质指标简化成2个主成分,主成分I代表水体的总磷、溶解性总磷和磷酸盐水平,是东太湖水域最主要的污染因子;主成分II主要反映水体的有机污染状况,叶绿素a和高锰酸盐指数的贡献率较大.利用主成分得分进行聚类分析,将12个采样点分为4类,北部由于受东山镇生活污水影响,各入湖河道口污染较为严重,特别是油车港;网围养殖区由于人工栽植的水草较为茂盛,水质较好,同东茭咀、太浦河口等水域的水质一样.

| Abstract: | Principal component analysis and cluster analysis were used to analyze the spatial zoning of water quality and the main water pollution characteristics in East Taihu Lake based on a systematic water environment research.The results showed that there existed a significant spatial pattern and obvious seasonal variations in water quality characteristics among the sites selected in East Taihu Lake.Two main components were obtained from twelve water quality indices,and component I was characterized by total phos... |
