摘    要:自1998年2月-1999年11月对胶州湾的10个站进行了大型底栖动物分布状况调查,目的在于为进一步的胶州湾生物多样性变化及其保护研究,为胶州湾底栖生物资源的合理开发和持续利用提供科学依据和积累资料。初步分析结果显示,两年内各站春季和秋季的物种多样性指数偏低,冬季和夏季的指数较高,物种均匀度指数夏季最高,春季最低,物种丰富度指数以夏季最高,春季和冬季略同,秋季最低。1999年各站出现的底栖动物种数明显高于1998年,差异显著,生物多样性平均指数较1998年有所下降。

关 键 词:胶州湾  大型底栖动物  物种多样性

Abstract:Field research of macrobenthic fauna at 10 stations in Jiaozhou Bay was carried out seasonally from February of 1998 to November of 1999. There were fewer species and the indices of biodiversity (Shannon-Wiener index) were lower in Stations 2, 3, 7 and 9 than in other stations. Stations 2 and 3 were situated in the inner area near Cangkou, a heavily polluted area. Stations 7 and 9 were situated at the mouth of the bay, where the bottom sediment was coarse sand. The indices in Stations 1 and 6, where the bottom sediment was soft mud, were high. The average Shannon-Wiener index of all the 10 stations was lower in 1999 than in 1998, although the difference was not remarkable. In both of the two years, the average Shannon-Wiener indices were lower in spring and autumn than in winter and summer; Pielou’s evenness index was highest in summer and lowest in spring; and the species richness index was slightly higher in winter and slightly lower in autumn. The relationship between biodiversity of the macrobenthos in Jiaozhou Bay and human activities should be studied further.
Keywords:Jiaozhou Bay  macrobenthic fauna  species diversity
