【Abstract】 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.更多还原
