| 摘 要： | 2003年9月大连湾和尚岛建港施工中产生大量悬浮泥沙,致使其附近筏养扇贝死亡.2004年我们对该工程附近海域养殖环境进行专项调查研究.本文通过40个站位样品分析实测资料对比,阐述了海湾沉积物类型的分布和变化状况,并通过聚类群分析对沉积物性态进行归类,划分了四个区(流塑浮泥区,软塑一流塑砂粘土区,软塑含砾粘土砂区,松散砂砾堆积区),其中流塑浮泥区为工程悬浮泥沙对海域底质影响区,其面积4～5 km2,文章最后对工程悬浮泥沙问题进行讨论.

| Abstract: | A large amount of suspended silt was produced in construction of Heshang Island port of Dalian Bay in Sep.2003,and caused the scallop's death cultivated in nearby rafts.A special investigation was carried out for the cultivating environment in the sea area near in 2004.The impact of the suspended silt on the sediment environment in sea area was discussed.Through contrast of the samples at 40 stations,the distribution and changes of the sediment type,and sorts were explained by the cluster group.It is divide... |
