浮游植物评价颍河水质污染研究

An Evaluation Of Water Pollution and Studies of the Ying River By Means of Phytoplankton

对颍河阜阳段浮游植物在 8个段面四季采样 ,进行了种类组成、种群数量、优势种、污染指示种、多样性指数、硅藻指数等群落生态学初步研究 .选用种群数量、优势种、污染指示种、硅藻指数对颍河阜阳段水质污染进行评价 .颍河阜阳段水质受到中等偏重程度的污染 ,属有机污染严重的河流 ,与过去颍河浮游植物调查资料相比 ,表明近年人为有机污染进程在加速 .

The seasonal ecological features of phytoplankton community including its species composition,pollution size,dominant species,saprobic indicator,diversity index,and diatom biolic index are preliminary studied at 8 sampling station in the Ying River,Fuyang segment. by using population densities(individuals and cells per litre),dominant species,saprobic indicators and diatom biotic index as the important biological parameters for monitoring and evaluating pollution conditions of water quality. All these indicate that the river has suffered from moderate pollution and it might be regarded as a heaver organic pollution river compared with Ying River's phytoplankton survey materials in the past and indicate people are accelerating organic pollution process in recent years.
