摘要
本文根据1994年7月和12月于厦门西港所获的调查资料，分析了浮游动物的丰度及其季节和年际变化，讨论了浮游动物的物种和生态类群多样性。结果表明，7月浮游动物湿重生物量月均值约为12月的2．56倍，与历史资料相比，呈逐年下降趋势；7月和12月在西港共记录浮游动物55种和多种浮游幼体，它们分别隶属于5个生态类群。文中还分析了潮汐对浮游动物分布的影响。
Based on investigation data of July and December, 1994 in western Xiamen Harbour,theabundance,and the seasonal and yearly variation of zooplankton were analyzed. The resultsshow that the average wet biomass of zooplankton in July is about 2. 56 times of that in De-cember,and compared to the precious data,there is a tendency to decrease year by year. To-tally, 55 species of zooplankton and many planktonic larvae were recorded in July and Decem-ber,which belong to 5 populations of coastal warm water,coastal warm and temperate water,estuary low-salinity,euryhaline and eurysalinity,and extensive high-temperature and high-salinity,and are mainly of coastal warm water population. The tidal effect on the distributionof zooplankton was analyzed. It is concluded that both biodiversity and abundance duringhigh tides are much higher that those during low tides,especially the euryhaline and eu-rysalinity species,and extensive high-temperature and high-salinity species, many of whichleave western Xiamen Harbour in ebbing tides.
