Based on the bottom trawl surveys in central Jiaozhou Bay from March to August 2009, and by using ecological diversity indices and canonical correspondence analysis (CCA), this paper studied the species composition of fish community, and analyzed the species diversity and its relationships with the environmental factors in the Bay in spring and summer. A total of 43 fish species were captured, belonging to 8 orders, 24 families and 38 genera. The number of fish species increased with increasing bottom water temperature. Margalef species richness index was from 2.440 to 2.770, Shannon diversity index was from 1.322 to 2.346, and Pielou evenness index was from 0.416 to 0.771. No significant differences were observed in the diversity indices between spring and summer. The ranks of the species composition and biomass in contiguous months had less change. Bottom water temperature was the most important environmental factor affecting the monthly change of fish species composition.
基于2009年3月至8月在胶州湾中部进行的底拖网调查，运用生态多样性指数和典范对应分析（CCA），研究了鱼类群落的种类组成，分析了春夏季胶州湾内的物种多样性及其与环境因子的关系。共捕获43种鱼类，隶属于8目24科38属。鱼类种类数随底层水温升高而增加。Margalef物种丰富度指数为2.440至2.770，Shannon多样性指数为1.322至2.346，Pielou均匀度指数为0.416至0.771。春夏季多样性指数无显著差异。相邻月份的种类组成和生物量排序变化较小。底层水温是影响鱼类种类组成逐月变化的最重要环境因子。
