研究利用中型生物扰动系统 (AFS)对胶州湾薛家岛潮间带菲律宾蛤仔 (Ruditapesphilippinarum)养殖断面和非养殖断面的中潮和低潮 4个站位的生物沉降和沉积物的再悬浮过程进行测定。结果表明生物沉降作用与大型滤食性双壳类动物 -菲律宾蛤仔的丰度呈显著的正相关关系 (r=0 .984 ,P<0 .0 5 ) ,养殖断面的生物沉降作用要明显地大于非养殖断面。在菲律宾蛤仔的低密度区 ,生物沉降的作用小于自然沉降 ,而在其养殖的高密度区 ,生物沉降率约为自然沉降率的4倍。薛家岛潮间带沉积物的临界侵蚀速率为 17.4～ 2 0 .4 cm/ s。沉积物的稳定性与所测生物因子的关系不密切 (P>0 .0 5 )。作者推测两个断面中潮站位沉积物的相对易侵蚀性 ,可能是由于此处环境受到某些大型动物及高潮带人工养殖带来的扰动所致
This study investigated the biosolvation and sediment resuspension of four stations in the mid-tide and low-tide of the sectioned and non-sectioned clams of Ruditapes philippinarum in the Xuejijima intertidal zone of Jiaozhou Bay in Jiaozhou Bay using the medium-scale bioturbation system (AFS) . The results showed that there was a significant positive correlation between biotile sedimentation and the abundance of large filter-feeding bivalve - Philippine Ruddy (R = 0.984, P <0.05), and the bioclastic sedimentation obviously Greater than non-breeding section. In the low-density region of Ruditapes philippinarum, the biological sedimentation is less than natural sedimentation, whereas in the high-density area where it is cultured, the biodeposition rate is about 4 times the natural sedimentation rate. The critical erosion rate of the sediments in the Xuejiadao intertidal zone is 17.4 ~ 20.4 cm / s. Sediment stability and measured biological factors are not closely related (P> 0.05). The authors speculated that the relative erodibility of sediments at the tidal station at the two sections may be due to disturbances caused by the artificial breeding of some large animals and orchards in this area
