摘　　要：应用水动力学、水质数学模型,以渤海湾海岸带的几种典型开发活动——围海造地、海水淡化和河口建闸为例,模拟分析海岸带开发活动对渤海湾近岸海域水环境的影响。研究沿海围垦造成的潮通量、近岸流场水动力条件和污染物输移的变化;分析海水淡化工程浓缩海水的排放,高盐度高浓缩污染物对局部生态环境的影响;分析河口建闸后蓄积的污水排放方式对河口及近岸海域造成的影响,大量污水一次性排放会增大河口及近岸海域污染面积和污染程度。The effect of several typical coastal exploitations on the water eco-environment of Bohai Bay is studied by application of a hydrody- namic and water quality modem. Details are given about the variations of hydrodynamic characteristic and the pollutant transport caused by reclamation engineering. And the influence on the local eco-environment, considering the discharge of concentrated sea water with high salinity, heat and pollutants for the seawater desalination project, is simulated. Analysis is also carried on about the pollutant＇s pulse impact due to different operation modes of the barrage on the river estuary, which influences the pollution range in the estuary and coastal area.
