| 摘 要： | 基于2016年5月至2017年2月在乐清湾进行的4个航次浮游动物调查数据,计算乐清湾浮游动物优势种的优势度指数(S)、平均拥挤度(X*)、生态位宽度(Bi)及生态位重叠值(Qik )。结果表明: 乐清湾海域浮游动物优势种(S＞0.02)共17种,生态位宽度值差异较大,优势度指数与生态位宽度值呈极显著正相关。浮游动物的生态位重叠值极低,Qik＞0.6的种对有25对。冗余分析表明,温度和盐度是影响乐清湾海域浮游动物优势种分布的重要因素,浮游动物优势种在这些环境因子上存在生态分化现象。

| Abstract: | The index of dominance(S),average crowding(X*),niche breadth(Bi),and niche overlap(Qik)of dominant zooplankton species were calculated using data collected from four zooplankton surveys from May 2016 to February 2017 in Yueqing Bay,Zhejiang Province.The results showed that there were 17 dominant zooplankton species(with S>0.02).The niche breadth values of those dominant species differed greatly and were positively correlated with S.The niche overlaps of zooplanktons were extremely low.The total amount of species pairs with niche overlap higher than 0.6(Qik>0.6)were 25 in Yueqing Bay,which represented 18.4%of the total pairs.Results from the redundancy analysis showed that the distribution of dominant zooplankton species was mainly affected by temperature and salinity,which caused ecological differentiation of zooplankton species. |
