摘要

根据2011-2012年春季北仑河口、九龙江口、瓯江口、长江口和灌河口的海洋综合调查资料;对不同河口浮游动物群落的生物多样性指数(H'),物种更替率(R)和群落相似系数(S)进行了分析;探讨了不同河口之间浮游动物群落的差异。结果表明:北仑河口和九龙江口为南部亚热带区系,H'分别为1.01和2.18,两河口之间R值为65.52%,S值为51.28%;瓯江口和长江口为中部过渡区系,H'分别为1.31和1.86,两河口之间R值为58.33%,S值为58.82%;灌河口单独为北部温带区系,H'值为1.19,与其余河口物种更替率均高于80.00%,群落相似系数均低于32.00%。线性回归结果表明:我国不同河口之间浮游动物的物种更替率与纬度差(两河口所处纬度的差值,?N)呈正相关关系(R=0.026?N+0.608,p=0.002);群落相似系数与纬度差呈负相关关系(S=0.034?N+0.578,p=0.001)。
Based on the zooplankton samples from stations in Beilun Estuary, Jiulongjiang Estuary,Oujiang Estuary, Changjiang Estuary(Yangtze River) and Guanhe Estuary(covering 14 latitudes)in April or May of 2010 to 2012, the community features of Diversity index(H'), replacement rate(R) and similarity coefficient(S) were compared. The results indicated that the zooplankton community of the five estuaries were divided into three different zooplankton fauna. The southern subtropical zooplankton fauna included Beilun Estuary and Jiulong Estuary. In this fauna, the subtropical species was the mainly and a different diversity index(H')(1.01 and 2.18) were recorded, located in the subtropical sea. In central transitional zooplankton fauna, constituted by Oujiang Estuary and Changjiang Estuary, it was exclusively of the subtropical species and warm temperate species, which had an alike diversity index(H')(1.31 and 1.86, respectively), situated in the transition waters between subtropical and temperate. At high latitude, only the Guanhe Estuary belongs to the northern temperate, the warm temperate species was dominated, which had a lower diversity index(H')(1.19) and located in the temperate sea.
