华南海岸带陆海相互作用研究

Research of Land and Ocean Interaction of the Coastal Zone in South China

全球环境变化背景下,海岸带陆海相互作用的重点应该放在地球系统的重要界面-海岸带。结合国外海岸带陆海相互作用研究,对我国华南海岸带历史与现代陆海相互作用研究的现状与问题进行较为详细的评述.并就华南海岸带开展陆海相互作用应研究的主要内容及趋势进行了探讨。

It is a fact that the key of the Land-Ocean Interaction (LOI) research focuses on coastal zone, a significant interface of the global system between land and ocean under current global changes. This paper firstly reviews in brief the research work on historical interactions between Land and Ocean of the Coast in South China (ILOCSC), which mainly includes two schools, the vicissitude of holocene shorelines and the evolution of sand- banks. Then, this paper analyses and discusses native studies on the modern ILOCSC including the evolution of coast and beach. Finally, based on above analyses, this paper raises main topics concerning the central contents and the general tendency of ILOCSC studies in the future as follows:(1) The response of geomorphologic configuration, sediment structure and beach state in South China coast to monsoon climate in East Asia and the information preservation of this response.(2) Comparative research on the modes of the dynamic geomorphology of the different coastal type in response to the various dynamic actions of land and ocean.(3) The mechanism analysis of dynamic action between land and ocean of the arc-shaped coast in South China.(4) Research and discussion on how to simulate and forecast shoreline deformation and the configuration of equilibrium profiles of the beach.(5) The processes of the adaptation and response of the coast in South China to the global changes, and the countermeasures on the problem of the sustainable development and the protection of the coast.
