| 摘 要： | 分析鉴定了1999年春、秋两季，在鄱阳湖区8个断面24个采样站采得的水样．共观察到各类浮游动物共150种．其中轮虫动物物种最为丰富，为96种，占总种数的64．0％，且单位体积的数量亦呈明显优势，说明轮虫动物是该湖区浮游动物的优势类群；其次为原生动物．24个采样站中，原生动物、轮虫动物、枝角类、桡足类这四类浮游动物个体数量分布的差异极大，其中第10、12、13和23号站中的个体数量较高，超过100ind／L最大数量出现在13号站，个体数量高达1101．60ind／L鄱阳湖浮游动物的数量有明显的季节变动，尤属轮虫的变动最大．本次调查中轮虫和枝角类的数量春季大于秋季，而原生动物和桡足类则秋季大于春季．

| Abstract: | The samples of zooplankton taken from 24 stations of 8 sections in Poyang lake in two seasons, spring and autumn in 1999, were identified. The 150 species of zooplankton was found, the most of which were rotifers. The species number of rotifer was found 96, reached to 64.0% in the total species, which showed that rotifers were preponderant genus. The protozoan took place in the second. The distribution of the quantities of the four genus, Protozoan, rotifer, cladocera and copepoda differed a lot in each stations, those of which No.10, 12, 13 and 23 station were in higher level, more than 100ind/L. The highest level appeared in No.13 station, whose quantities were 1101.60ind/L. The amount of zooplankton changed with seasons apparently, while rotifers fluctuated more. The quantities of rotifer and cladocera were more in spring than in autumn, while protozoan and copepode were just opposite. |
