|本文利用极点排序及聚类的多元分析方法, 对武汉市湖泊浮游植物群落结构进行了研究, 将排序结果与水质分类结果进行比较, 结果表明:东湖和龙阳湖由于受到人为因素的干扰而使得其浮游植物群落的结构特征与其水质状况不太一致.然后再利用生态学的观点对结果进行分析解释, 并为武汉市水环境治理与保护提供了科学的生态保护措施.

|A multianalysis method-polar ordination and cluster-was adopted to investigate the structure of phytoplankton of Wuhan lakes.By comparing the results of ordination and water quality classification, It was proved that the structrual characteristics of the phytoplankton of Lake Donghu and Lake Longyang do not conform to their water quality status due to human disturbances.Hence, the ecological explain was accepted in the article and also some scientific ecological measures were endued to manage and protect the Wuhan's water environment.
