| 摘 要： | １９８６～１９８７年对丹江口水库浮游生物调查结果表明：该水库浮游植物以蓝藻门、绿藻门、硅藻门种类较多；浮游动物有轮虫、原生动物、枝角类、桡足类等。浮游动物和浮游植物月平均密度分别为１．０７８×１０６个／ｌ和４．９４０×１０３个／ｌ，月平均生物量为１．６０３ｍｇ／ｌ和０．６４６ｍｇ／ｌ。另外，作者还分析了各采样点及其不同采样时间的浮游生物的差异。该水库浮游生物所提供的鱼产潜力分别为：鲢１２９３．６万ｋｇ、鳙７８５．９万ｋｇ；鱼种投放量为３９２２５．４万尾，平均每亩投放４寸鱼种４２２尾（鲢３０９尾、鳙１１３尾）。

| Abstract: | The resource of Plankton of Dan Jiangkou reservoir Was Surveyed in 1986-1987. The results indicated: Cyamophyta, Chlorophy and Bacillariophyta were its main Phytoplankton, there were four kinds of Zooplankton in this reservoir. The biomass of Phytoplankton and Zooplankton were 1.603 mg/l. and 0.646 mg/l respectively. Auther also discussed the difference of biomass, density according to site and time. Fish productivity of Corp (Hypophthalmichys molitrix) and big-head silver Cavp (Aristichthys nobils) were estimated. |
