为了解胶州湾大型底栖动物群落结构和多样性现状，于2018年4月、7月、10月和2019年1月在胶州湾8个采样点进行了调查。共采集到大型底栖动物82种，其中环节动物30种，软体动物21种，甲壳动物20种，棘皮动物8种，其它3种，夏、秋、冬三季菲律宾蛤仔为常见优势种。年平均丰度和生物量为280个/ m2和446.45g/m2。Shannon-Wiener多样性在0.09 ~ 2.45之间，平均值为1.14。Margalef丰富度为0.17-2.32，平均值为0.89。Pielou均匀度为0.14-1.00，平均值为0.71。各指标的季节变化规律基本一致，春季最高，冬季次之，夏秋季较低。不同调查站的多样性差异很大。
To understand the current community structure and diversity of macrobenthos in Jiaozhou Bay, a survey was conducted at eight sampling stations in April, July, and October 2018, as well as January 2019. Eighty-two macrobenthos species were collected, including 30 of Annelida, 21 of Mollusca, 20 of Crustacea, 8 of Echinodermata, and 3 classified as “Others”.Ruditapes philippinarumwas a common dominant species in summer, autumn, and winter. The annual average abundance and biomass were 280 ind./m2and 446.45 g/m2, respectively. Shannon-Wiener diversity varied from 0.09 to 2.45 with an average value of 1.14. Margalef richness was 0.17–2.32 with an average value of 0.89. Pielou evenness was 0.14–1.00 with an average value of 0.71. The seasonal variation patterns of all tested indices were largely the same, with the highest in spring, next highest in winter, and lower in summer and autumn. The diversity at different survey stations varies greatly.
