摘要
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 。
According to the investigation on the zooplankton at six locatities of Dongping Lake during the low ,high and common water seasons in 1994,total 66 genera,100 species of Rotifera,Cladocera,Copepoda and Protozoa were obtained and identified,and their quantites,distribution as well as changes in seasons were found out,and 15 speeies indicating lightly,β moderately and amoderately polluted zones and their distribution were determined,Based on the quantitative statistical results of zooplankton and combination with other methods,confirmed that Dongping Lake belongs to mesotrophic eutrophic type.In the light of the principle of synthetic control eutrophication,the author proposed to stock rsilver and bighead carps and their rate,in order to reduce periphytic algae and zooplankton in the lake and control eutrophication,develop aquatic breeding products and tourism,thus achieving sustainable development.
