摘　　要：对沙溪竹洲水电站水体的富营养化评价结论：水体总氮超出评价标准，库区具有藻类生长的营养条件，磷是藻类生长限制因子。3种评价方法结果基本一致，表明水体处于贫营养向中营养过渡类型，并现出向富营养化发展的趋势。库区浮游动物种类以轮虫（rotifera）和原生动物（protozoa）为主，浮游植物种类以绿藻门（Chlorophyta）和硅藻门（Bacilariophyta）为主，库区应属于中营养类型。The concentration of total nitrogen in surface water excees data from assessmemt criterion. The nutrition condition of mass algae reproduction has been provided in reservoir area. Phosphorus element is the limit factor of algae growth. The results of three different evaluating methods are basically accordant. It is indicated that the water quality is in transition style from poor nutrition to medium nutrition, and exhibits the tendency to rich nutrition. The priority species of zooplankton in reservoir area are rotifera and protozoa, Meanwhile, the priority species of phytoplankton are Chlorophyta and Bacilariophyta.
