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/m^2。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。
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/m^2. 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.
