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。
In September 2003, a large amount of suspended sediment was produced in the construction of the island of Bhanghang Island in Dalian Bay, resulting in the death of scallops in the vicinity of the raft. In 2004, we conducted a special investigation on the aquaculture environment in the sea near the project. Based on the comparison of measured data from 40 stations, the distribution and changes of sediment types in the Gulf are expounded, and the sediment properties are classified by cluster analysis. Four zones (fluid plastic floating zone, Soft-plastic first-rate plastic clay zone, soft plastic gravel clay sand zone, loose grit accumulation area), of which the suspended plastic suspended sediment engineering sediment on the sea floor sediment impact area, the area of 4 ~ 5 km2, the last article Engineering suspended sediment problems are discussed.
