摘　　要：本文研究了围填海对连云港海区海洋动力环境的影响,通过分析连云港海洋站的实测数据,给出了连云港近海的水动力特征;基于ADCIRC建立了渤黄海的潮汐和风暴潮模型,利用海洋站的潮位资料和增减水资料验证了模型的适用性,模拟了填海前和填海后的潮位,分析了不同情况下潮汐的变化;并利用该模型研究了围填海对可能最大风暴潮的影响。研究结果表明:围填海引起了分潮振幅的变大,尤其是M2分潮,最大增幅能达到5.5 cm;围填海对风暴潮增减水有一定影响,距离填海区越近影响越大,徐圩港区周边可能最大增水极值变化范围为-27~18 cm。This paper studied the influence of reclamation on the marine dynamic environment in Lianyungang.Based on the analysis of the measured data of Lianyungang marine station,the hydrodynamic characteristics of Lianyungang before large-scale reclamation were described.The tidal and storm surge models of the Bohai Sea and the Yellow Sea were established by using ADCIRC,and verified by using the tide and storm surge data observed from marine station.The tidal levels before and after reclamation were simulated,and the tidal changes under different conditions were analyzed.The model was used to study the impact of reclamation on the possible maximum storm surge.The results showed that the amplitude of the main component of astronomical tide became larger in the reclamation area,especially the M2 tidal component with the amplitude variation reaching 5.5 cm.Reclamation had a certain impact on the storm surge,the amplitude change was obvious in the reclamation area.The variation range of the probable maximum storm surge around Xuwei port area was-27~18 cm.
