摘　　要：砂质岸线动态变化较大、不稳定,开展砂质岸线的动态变化监测,分析其动态变化特征及诱因对砂质岸线的保护和开发有着重要作用。基于唐山市1987、2000和2014年landsat影像,开展了唐山市砂质岸线变迁分析研究。结果表明:(1)1987~2000年,主要受来沙量减少、海洋动力的影响,唐山市砂质岸线全面处于侵蚀状态,其中滦河口—浪窝口段的弧形海岸侵蚀最为强烈;(2)2000年以后,由于人类工程建设,人工海岸增加,砂质岸线侵蚀速率有放缓的趋势。随着人类对海岸干预程度的加强,海岸演变趋势也必将更加复杂。本文提出了退养还湿、海滩养护等防止砂质海岸侵蚀的措施。Sandy coastline is unstable and its dynamic changes are highlighted. Carrying out the dynamic monitoring of sandy coastline to analyze its features and incentives,plays an important role in sandy coastline protection and devel- opment. Based on landsat images of 1987,2000 and 2014,this paper analyzed the study of sandy coastline changes in Tangshan. The results show that ： （ 1 ） Influenced by the sediment reduction and ocean dynamic, sandy coastline overall was eroded from1987 to 2000, especially the strongest erosion of the arc-shaped coast in Luanhe Estuary-Langwo Estu- ary. （2） After 2000, due to artificial construction and artificial coast increased, the erosion rate of sandy coastline was slowing down. With the strengthening of human intervention ,the trend of coastline evolution will be more complex. This paper puts forward some reasonable measures to prevent sandy coastal erosion, such as returning aquaculture ponds to wet land and beach nourishment.
