摘　　要：本文基于1993、2006、2013年遥感影像提取渤海大陆海岸线,分析了渤海海岸线和围填海的时空演变。研究表明:20a间渤海大陆海岸线长度共增加611.81km,形成陆地1888.30km2,1993-2006年影响渤海岸线变迁的主要因素为滩涂围垦,2006年以后填海造地工程对岸线变迁的影响加剧并成为主要因素;天津大港岸段、河北滦南县-唐海县岸段的岸线开发几近饱和,几乎不具备继续围填海的潜力,建议对已成陆区采取优化开发策略;天津塘沽、山东寿光、辽宁大洼岸段围填海强度较大,继续围填海的潜力很小,建议严格控制新增围填海规模,加强对已成陆区的集约利用,以提高利用效率。Shorelines in the Bohai Sea are extracted from satellite images in the year of 1993, 2006 and 2013. The spatial-temporal evolution of the shorelines and the corresponding sea reclamation during the recent 20 years are analyzed. The results show that the shoreline length was increased and the land area were growing into the Bohai Sea by about 611.81km and 1888.30km2, respectively. The many factors for the changes are tidal flat reclamation in the period. The sea reclamation projects have been intensi- fied and proved to be the uppermost factor since 2006. Optimized development policy should be given to the overused shoreline segments where have almost no reclamation potential, including the shoreline segments near Dagang and from Luannan to Tanghai. The police of strict controlling the scale of sea reclamation and strengthening the intensive use of shoreline segments should be taken for Tanggu, Shouguang and Dawa, where have less reclamation potential, in order to increase the efficiency of the usage.
