摘要:

2015年10月和11月调查了海州湾潮间带A、B 2个断面的大型底栖动物，共发现大型底栖动物29种，其中A断面发现19种，B断面23种；潮间带大型底栖动物的总平均丰度为1 790 m^-2，总平均生物量185.11 g/m²。A、B 2断面的丰度生物量差异较大，主要是由于2个断面底质类型不同造成的。潮间带Shannon-Wiener多样性指数平均值为2.90，波动为2.44～3.45，其沉积物环境存在轻度有机质污染。

Abstract:

Macrobenthos were investigated at 2 sections in the intertidal zone of Haizhou Bay in Oct. and Nov. 2015. We identified a total of 29 species, of which 19 species in section A and 23 species in section B. The average abundance of macrobenthos was 1 790m^-2, and the average biomass was 185.11g/m². There were great differences in the abundance and biomass of section A and B, which was mainly caused by the different sediment of the two sections. The mean Shannon-Wiener index was 2.90, with a range of 2.44~3.45. Our results indicated that the sediment has been slightly polluted.
