摘要:
基于2018年5月胶州湾海域共计20个站位所获取的生物及环境数据，研究胶州湾大型底栖生物多样性以及群落结构特征。调查海域共发现大型底栖生物208种，大型底栖生物总平均丰度和生物量分别为2 654.38 ind./m²和1 024.512 2 g/m²，大型底栖生物物种数、丰度和生物量均呈现北部高、南部低的分布趋势；调查海域优势种以多毛类为主，I_RI值最高的物种为菲律宾蛤仔Ruditapes philippinarum；香农维纳指数与ABC曲线均表明调查海域底栖生态环境整体清洁；在40%相似性水平上，可将调查海域大型底栖生物划分为4个群落；底温和底盐影响调查海域大型底栖生物丰度分布。

Abstract:
Biological and environmental data were obtained from 20 stations in Jiaozhou Bay in May 2018 to investigate the diversity and community structure of the macrobenthos. A total of 208 macrobenthic species were found in the survey area, with an average abundance of 2 654.38 individuals/m² and an average biomass of 1 024.5122 g/m². The species richness, abundance, and biomass were higher in the northern area than in the southern area. Most of the dominant species were polychaetes, with Ruditapes philippinarum being the most dominant. Both the Shannon-Wiener index and the ABC curve showed that the benthic ecological environment in the survey area was undistured. At 40% similarity level, 4 commumities could be clustered. The abundance of the macrobenthos was influenced by temperature and salt content of the bottom water.
