摘要
枯水期嘉陵江小三峡有４个附生藻类群落，即刚毛藻群落、颤藻－鞘丝藻群落、直链藻－等片藻群落和鱼子菜－红毛藻群落。根据Ｆｊｅｒｄｉｎｇｓｔａｄ提出的以生物群落指示环境污染，结合Ｋｏｌｋｗｉｔｚ的污水生物系统，以及枯水期小三峡浮游藻类优势种和其它理化指标进行综合分析结果表明，枯水期小三峡水质污染程度由低到高排列顺序为：沥鼻峡＜温塘峡＜观音峡，除毛背沱和水土沱为α－中污带水质外，其余各点均为β－中污带水质。
There are four attached algal communities in the little three gorges of Jialing kiver during the low-er water periods, namely,the Cladophora community,Oscillatoria-Lyngbya community,Lemanea-Bangiacommunity and Melosilsa-Diatoma community,According to the views of Fjerdingstad,i. e. ,the biologi-cal communities can indicate the enviromental pollution,and by the saprobic system of Kolkwitz,associ-ated with the analyses on the planktonic algal dominants in the little three gorges during the lower wa-ter periods and ofther physichemical indices we know that the polluting degree at lowest water periodsin the little three gorges are Lipi gorge<Wentang gorge<Guanying gorge,The Maobituo and Shuitu-tuo sampling spots belong to α-mesosaprobic zone in water quality,while the others belong to β-mesos-aprobic zone.
