| 摘 要： | 结合海洋生态系统动力学研究，以碳为基本 单位研究了胶州湾北部浮游动物的生物量和生产力的季节变化和平面分布及其周转率等。浮 游动物生物量的变化范围为8.73 ～ 24.05 mgC/m3；生产力的变化范围为0.26 ～ 1.09 mgC /m3.d。二者具有显著的季节变化。 其平面分布表现为不均匀性。海水中Chl a的含量、 初级生产力及盐度等是影响浮游动物生物量和生产力的主要因素。该水域浮游动物的周转率 平均为0.047(0.019 ～ 0.13)，其变化与水温呈显著正相关，与浮游动物平均个体干重呈负 相关。

| Abstract: | The seasonal variation, horizontal distribution and turnover rate of the zooplankton in northern Jiaozhou Bay (Qingdao, China) were studied over the period March 1995 to January 1996. The sampling scheme included bi-monthly hauls from the bottom to the surface of the water by using a plankt on net (0.5m diameter, 505 μm mesh size) at eight stations. The zooplankton bio mass varied from 8.73 mgC/m3 to 24.05 mgC/m3, and the zooplankton productivi ty fluctuated between 0.26 mgC/m3.d and 1.09 mgC/m3.d. Both of them had significant seasonal variations. Among the factors that influenced the fluctuati ons of zooplankton biomass and productivity, chlorophyll a and phytoplankton pro ductivity and salinity played an important role. There was remarkably positive c orrelation between the turnover rate of zooplankton and the temperature, and the re was significantly negative correlation between it and zooplankton dry weight. |
