摘　　要：利用不锈钢环形采泥器 ,在胶州湾潮间带沿天然断面选取典型站位 ,现场采取无扰动沉积物样品 ,应用生物扰动实验系统 (Annular Flux System) ,选用菲律宾蛤仔 (Ruditapes philippinarum)和缢蛏 (Sinonovacula constricta) ,在实验室内进行实验。结果表明 :菲律宾蛤仔个体的生物沉降率平均为 0 .15g/ m2 · h· ind,平均净生物沉降率为自然颗粒沉降率的 3.0 5倍 ;缢蛏个体的生物沉降率平均为 0 .2 9g/ m2·h· ind,平均净生物沉降率为自然颗粒沉降率的 2 .6 3倍。Sediments were sampled with minimal disturbance by using stainless steel corer at stations along shore transect from immediately below the bank to the mid tide level of the intertidal mudflat of Jiaozhou Bay. Biodeposition experiments were conducted by using two species of typical suspension feeding clams( Ruditapes philippinarum and Sinonovacula constricta) in Annular Flux system, a portable benthic annular flume. The results show that: the average Net Biodeposition Rate of Manila clam ( Ruditapes philippinarum ) is 0.15g/m 2·h·ind, and its mean biodeposition rate is 3.05 times of the Natural Sedimentation Rate; and the average Net Biodeposition Rate of Sinonovacula constricta is 0.29g/m 2·h·ind, and its mean biodeposition rate is 2.63 times of the Natural Sedimentation Rate.
