摘　　要：2006年2月-10月,对引滦原水藻类的群落结构及影响因素进行了调查研究。期间引滦原水中共检出藻类7门43属68种,藻类群落结构呈明显的季节性变化。春季和秋季的引滦原水中以绿藻为优势类群,藻类含量较低;夏季水温升高,水华微囊藻大量增殖并成为绝对优势种,藻类含量因而大幅上升,同时导致了原水藻类多样性指数的大幅降低。相关性分析表明,在目前的水质条件下,水温是影响引滦原水藻类群落结构变化的关键因素。To provide consultation for algae removal,an investigation on phytoplankton community in Yinluan raw water was conducted during February to October 2006.It was shown that there were 68 species of phytoplankton in Yinluan raw water,which belonged to 7 phylum and 43 genera.And the structure of the species and concentration of phytoplankton varied seasonally.Chlorophyta was dominant in spring and autumn with low phytoplankton concentration.in while summer,Microcystis flos-aquae was dominant with high phytoplankton concentration,and Microcystis flos-aquae＇s multiplying sharply lead Shannon index to decline.The correlation analysis indicated that water temperature was the key role in variation of phytoplankton community.
