【摘要】 于2001年9月~2002年9月对大连黑石礁海区浮游动物的生态学进行了调查研究,共鉴定出桡足类13种,枝角类4种,其它为毛颚动物、被囊动物、轮虫和原生动物等,桡足类是浮游动物中的主要类群;浮游动物数量和生物量的周年变化基本上为单峰形,高峰期位于8月。回归分析表明,浮游动物数量的变化与水温有一定的相关性。此外,黑石礁海区浮游动物群落小型化趋势较为明显。更多还原

【Abstract】 The community structure and temporal and spatial distribution of zooplankton in Heishijiao coastal area in Dalian was studied from September, 2001 to September,2002.The results showed that there were 13 copepod species, 4 cladocera species and others such as chaetognatha,tunicate,rotifer and protist in the zooplankton community,in which the copepod were the predominant.The annual variation model of abundance and biomass of zooplankton was single apex model and the peak value occurred in August.Regression analysis indicated that there existed correlation between variation in zooplankton and water temperature.In Heishijiao coastal area,micro-zooplankton was dominated in zooplankton community.更多还原
