摘　　要：通过对北戴河新区洋河-葡萄岛岸段剖面监测资料的分析,得到该段海滩沙坝建设前的演变特征。基于水动力和地形资料,采用GENESIS数值模型建立该岸段的岸线演变模型,使用实测的剖面资料进行验证,并预测了沙坝工程建成后3个月、6个月、1 a、5 a和10 a的岸线演变。结果表明:沙坝建设及刚完成期间,海滩迅速增宽,后经季节变化调整,1 a逐渐形成新的动态平衡;长期来看,岸段总体呈现东冲西淤的状态,趋于平直。Based on the analysis of profile measurements at Yang River-Putao Island coast at New District, Beidaihe, we obtained the natural evolution characteristics before the bar nourishment. A shoreline evolution model is established for the beach using GENESIS according to the observations of hydrodynamic and topography and verified against the shoreline data.Predictions on the shorelines after the bar nourishment are conducted by the model in terms of 3 months, 6 months, 1 a, 5 a and 10 a. Conclusions can be gained that the beach quickly increased in width during the construction period and after the bar nourishment then adjusted to the seasonal variations of hydrodynamic, and finally reached to a new equilibrium state in 1 a. In general, the shoreline appears as erosion in east part and deposition in west part and tends to straightness.
