根据 1994年对东平湖 6个采样点枯水期、丰水期、平水期浮游动物的调查 ,共获轮虫、枝角类、桡足类和原生动物 6 6属 10 0种 ,查明其数量和分布以及季节变化状况 ,确定了指示轻污带、β-中污带和α-中污带的 15个种及其分布。根据浮游统计结果 ,结合其它方法 ,肯定了东平湖为中营养型—富营养型湖泊。按照综合防治富营养化原则 ,作者提出放养鲢鳙及搭配比例 ,以减少湖中着生藻类和浮游动物 ,防治富营养化 ,发展水产养殖业和旅游业 ,实现了可持续发展 According to the survey of zooplankton in dry, wet and flat water of 6 sampling sites in Dongping Lake in 1994, a total of 106 species of rotifers, cladocerans, copepods and protozoa were detected in 6 6 genera, Distribution and seasonal changes, identified 15 species and their distribution of light pollution zone, β-medium pollution zone and α-medium pollution zone. According to the results of planktonic statistics and other methods, it is confirmed that Dongping Lake is a medium-nutrient-eutrophic lake. In accordance with the principle of comprehensive prevention and control of eutrophication, the authors put forward the stocking of silver carp and bighead carp with the proportion to reduce the algae and zooplankton in the lake, prevent and control eutrophication, develop aquaculture and tourism, and achieve sustainable development
