胶州湾中部海域大型底栖生物生态学初步研究

Preliminary ecological study of the macrobenthos in the middle part of the Jiaozhou Bay

2006年8月～2007年10月分4个航次对胶州湾中部海域进行大型底栖生物调查。调查结果表明,大型底栖生物总平均丰度和总平均生物量为1507个/m^2和35.88g/m^2。与历史资料做了对比,并初步分析了与以往调查结果不同的原因。调查海域大型底栖生物多样性指数和丰度生物量比较曲线显示,胶州湾中部海域底栖生物处于轻微扰动状态。

The macrobenthos in the middle part of the Jiaozhou Bay was investigated during the period of August, 2006 to October, 2007.The total mean abundance and biomass were 1 507 inds./m2 and 35.88 g/m2, respectively.Compared with the published data on this area, there were some differences between our results and previous investigations. The indices of biodiversity and the comparison curves of the abundance and biomass indicated that the macrobenthos community in this area had been slightly disturbed.
