胶州湾中部海域大型底栖生物生态学初步研究

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.
