港湾工程造成了泥沙的直接入海、改变岸线和海底形态以及海湾的动力形态、从而影响海湾沉积环境.各时期工程对沉积环境的影响呈现累积效应,其结果使海湾的沉积速率增大、沉积物特征变化,沉积物中的活性物质对某些污染物吸附富集,沉积物化学环境也产生变化,一些元素形成量的累积.

Harbor infrastructures affect the deposit environment in the harbor because it leads to the sand going into the sea immediately, modify the shore and sea bed and the shape of the harbors, thus the changing of sedimentation environment.Each period of the project affects the sedimentation environment accumulatively.As result, sedimentation in harbor speeded and characteristic of the sediments was changed. The absorption of some active materials in the sediments to some contaminants is enriched and the chemical environments changed. At last, some elements accumulated quantitatively.
