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。
A typical stainless steel ring dredger was used to select the typical stations along the natural section in the intertidal zone of Jiaozhou Bay. Undisturbed sediment samples were taken on site. Annular Flux System was used to select Ruditapes philippinarum and 缢 蛏(Sinonovacula constricta), experiments in the laboratory. The results showed that: the average sedimentation rate of individuals in Ruditapes philippinarum was 0.15g / m2 · h · ind, the mean net sedimentation rate was 3.05 times that of natural sediments; the average sedimentation rate of individuals was 0.22g / m2 · h · ind, the average net sedimentation rate of 2.6 times the natural rate of sedimentation of particles.
