海岸线修测中围海养殖区岸线界定问题分析

海岸线作为海洋与陆地的分界线，是海域管理的重要界限和基础地理数据，也是地图编绘、海洋调查和海岸带演变研究的重要内容，准确掌握其位置、长度等信息，是提高海域管理科学化水平的必不可少的环节。文章结合广东省海岸线修测实际工作中发现的问题，对围海养殖区海岸线界定方法进行探讨。针对养殖区已进行土地确权的情况进行深入分析，并提出：以自然属性为主要依据判定海岸线位置；承认土地权利人的权利在先；围海养殖区的海岸线统一以靠陆一侧的外边缘线进行界定等解决方案。期望可以为海岸线修测和海域管理提供有益的参考。

Analysis on Definition of Coastline of Sea Reclamation Aquaculture in the Coastline Survey

As the basic geographic boundary between ocean and land,coastline is an primary content of map compilation,marine survey and coastal zone evolution research.Accurately grasping its location,length and other information is an essential link to improve the scientific level of maritime management.Method on definition of the coastline of sea reclamation aquaculture was analyzed and discussed in this paper based on the problems found in the coastline survey of Guangdong Province.The situation was analyzed and some suggestions were put forward in view of the fact that the right of land has been confirmed in the aquaculture area.And the following solutions were put forward: location of the coastline should be determined based on the natural attributes,the rights of land owners should be recognized and the coastline of the coastal aquaculture area should be defined by the outer edge of the land side.It is expected to provide useful reference for coastline survey and marine management.
