摘　　要：根据1980年以来的历史地形资料,分析了连云港西导堤、连云港区东扩、灌河口双导堤和徐圩港区等工程建设对连云港海域地形的影响。分析表明,近岸大型工程建成后对沿岸地形带来的影响仅限于5 m等深线以内的区域,冲淤幅度较大;5 m等深线以外区域基本处在工程影响范围外,海床冲淤幅度较小。上述研究为相关工程的影响评价提供了参考。随着徐圩港区大规模建设,对该海域海床演变的影响将逐步显现,建议继续对连云港—徐圩海域开展动态监测,分析海床和岸滩稳定性变化及其对航道的潜在影响。According to the historical topographic data since 1980,we analyzed the effect on topographic change by the engineering construction at Lianyungang area,such as west breakwater,port eastern expansion,dual jetty in the Guanhe estuary and Xuwei Port etc.The results show that the impacts on the coastal topography change are limited to the region within 5 m isobath,and the scouring and silting rate is greater than other regions due to the influence of nearshore large-scale engineering.The scouring and silting rate in the regions beyond 5 m isobath is small.The research provides a reference for the evaluation of related engineering project.With the large-scale engineering constructing of Xuwei Port in the future,the influence to the seabed evolution will gradually appear.It is suggested to conduct monitoring on the topographic evolution at the sea area from Lianyungang to Xuwei,and analyze the seabed stability and its potential impact on the waterway.
