泥河水库浮游植物数量变动及种群分布

报道了2000年5、7、9月份泥河水库浮游植物调查研究结果。由于2000年严重干旱，造成泥河水库极度富营养化。浮游植物平均生物量为330．06mg/L，其中蓝藻占61．5％，绿藻占25．5％。同时讨论分析了浮游植物的垂直分布规律，影响浮游植物水平分布的因素，泥河水库浮游植物群落的季节演替特征，以及浮游植物同渔产力的关系。测定了泥河水库白鲢的渔产潜力为1701000kg。

The Changes in Number and Population Distribution of Phytoplankton of Nihe Reservoir

This paper embodies the results of study on the phytoplankton of Nihe reservoir during 5, 7, 9 months in 2000. The average biomass of phytoplankton is 330.06 mg/L, the biomass of Cyanophyta is 61.5% and Clorophyta is 25.5% in biomass of phytoplankton. At the same time, mutual relationship of phytoplankton and fish production was discussed, the principle of vertical distribution and the fcators influncing the horizontal distribution of phytoplankton in Nihe reservoir were also studied.
