海岸缓冲区研究——以莱州湾东岸为例

Study on the Coastal Buffer Area——A Case of Eastern Coast of Laizhou Bay

结合莱州湾东岸晚更新世以来陆海相互作用历史与近期变化,分析了7 k a尺度上的古岸线变迁及近期影响缓冲区范围的河流地貌标志、海岸侵蚀标志、咸-淡水过渡带标志以及陆-海-大气相互作用标志,对海岸缓冲区的结构与功能及缓冲区范围做了初步分析,同时阐述了设置海岸缓冲区的必要性与可行性.

The ancient coastline change in scale of 7 ka and the each recent sign, including the river geomorphology sign, the coastal erosion sign, the exchange belt sign between salt water and freshwater and the interaction sign are analyzed based on land-ocean interaction and its late variety in the eastern coast of Laizhou Bay since late Pleistocene Epoch. The frames, functions and limits of coastal buffer area are researched. The necessity and feasibility for establishing coastal buffer area are presented synchronously.
