| 摘 要： | 根据１９９８年２－３月完全原庆湖梅梁湾地区水环境综合调查，对有关浮游动物时空情况进行了分析，这次调查共设７个点，湾口上的Ｊ２，Ｊ４与湾内的Ｊ６，Ｊ７均是分５层采样，共分无风，小风和大风３次天气过程，每次过程采集２到３次样品与记录。结果显示，太湖梅梁湾地区浮游生物中枝角类和桡足类的生物量与水温变化关系密切，水温越高，生物量越高，温度相同时，其生物量与透明度呈正比。

| Abstract: | From February to March in 1998, 7 sampling stations were fixed in Meiling Bay, Taihu Lake for the aquatic environmental investigation. Five of them (F1, J2, F3, J4, F5) were located on the mouth of the bay, the other two inside of the bay. The zooplankton samples wcre collected twice to three times on February 24, a gentle breeze day, on February 26, a calm day and on March 11, a strong windy day. There were 5 sampling layers in J2, J4, J6 and J7. The dominant direction of wind was north during the sampling days. Based on the samples analyses, it shows that the zooplankton abundance of cladocera and copepoda in the bay has close relationship with the water temperature. The higher water temperature, the higher abundance and there exists linear corelation between the abundance and the secchidisc transparency at the same water temperature. For the horizontal distribution of zooplankton, the zooplankton abundance inside the bay is higher than it on the mouth. For the vertical zooplankton distribution, the majority is at the 2nd and 3rd layers under the condition of February 24 and 26 but the uniform distribution under strong wind condition of March 11. |
