【摘要】：受全球及海岸带区域环境过程与人类活动的综合影响,海岸线发生剧烈的变化,对生态、环境及经济社会的影响不容忽视,海岸线变化相关研究因此得到普遍的关注。在讨论海岸线的定义和分类的基础上,介绍岸线信息提取的方法与技术,总结国内外海岸线变化的特征、机制与影响方面研究的进展,并指出未来研究的趋势,包括:对海岸线变化过程进行动态监测仍将是普遍关注的研究重点之一;对海岸线变化特征、规律与机理的认识已经日益深化,基于大量高精度数据和机理模型的研究已成为热点和前沿问题;针对不同的海岸带区域,聚焦海岸线变化的原因和机制及其对环境和生态的影响,以及不同区域之间的相互联系与影响特征,这将是未来研究的重点之一;中国海岸线变化的独特性、复杂性突出,促进和支撑中国的海岸带综合管理实践,提高决策者与管理者对岸线变化所带来的灾害风险的重视,为中国海岸带的科学规划与发展提供依据,这应该是我国海岸线变化研究的重要目标。
[Abstract]:Influenced by the global and coastal environmental processes and human activities, the coastline changes dramatically, and the impacts on ecology, environment and economic society can not be ignored. Therefore, the research on coastline change has been paid more and more attention. On the basis of discussing the definition and classification of shoreline, this paper introduces the methods and techniques of shoreline information extraction, summarizes the characteristics, mechanism and influence of shoreline changes at home and abroad, and points out the trend of future research. Including: dynamic monitoring of the process of coastline change will still be one of the research focuses of general concern; the understanding of the characteristics, laws and mechanisms of coastline changes has been deepened day by day. Research based on a large number of high-precision data and mechanism models has become a hot and frontier issue, focusing on the causes and mechanisms of shoreline changes and their impact on environment and ecology in different coastal zones. This will be one of the key points of future research. The uniqueness and complexity of the coastal changes in China will promote and support the integrated coastal zone management practice in China. Increasing the attention of decision makers and managers to the disaster risk caused by the shoreline changes provides the basis for the scientific planning and development of the coastal zone in China, which should be an important goal of the study on the coastline change in China.
