摘　　要：砂质海滩对于海岛旅游及可持续发展具有不可估量的价值,伴随着沿海开发进程的推进,海岛砂质海滩的稳定性逐渐受到考验,与其相关的海滩侵蚀问题日益凸显。文章通过对唐山市沿海一线海岛沙滩的踏勘,结合卫星影像资料,分析了2010—2016年唐山海岛沙滩的长度、面积变化,结果表明受陆域来沙减弱及海洋动力诸如风暴潮的作用及人工构筑物(虾池)等原因,唐山海岛沙滩长度、面积每年在以较快的速度不断缩减。同时,以唐山湾三岛(祥云岛、菩提岛、月岛)为例,提出了对三岛及周边环境进行综合整治修复相应的方案,包括退养还滩、沙滩整治修复、防浪促淤工程、生态廊道构建等工程,以期为当地决策者提供可行的建议。It is very important of sand beach for sea island tourism and its sustainable development.However,the stability of sand beach of sea island gradually faces much more challenge from the rapid development of offshore engineering.With the datum of field geological reconnaissance in the sand beach of sea islands of Tangshan and relative satellite images,this paper analyzed length and area changes of sand beach on sea islands of Tangshan in 2010-2016 and indicated which rapidly reduced every year as the reduction of terrigenous sand and impaction of marine hydrodynamics such as storm surge and artificial structures(shrimp ponds).Some regulation and restoration ideas for these three islands (Xiangyun island,Yue island and Puti island) were also proposed in this paper,such as retirement method,restoration of sand beach,wave prevention and promoting sedimentation works,construction of Ecological Corridor,to provide local decision maker feasible advices.
