COASTLINE CHANGES AND THEIR ORIGIN IN THE SOUTHERN HAINAN ISLAND
-
摘要:
海岸带是陆地和海洋相互作用的地带，是人类活动最为活跃、经济相对发达的地区，同时也是自然生态环境相对脆弱、资源环境承载力相对有限的地区。海岸线的变化情况研究对海岸带资源开发与保护有着重要的意义, 而遥感技术对海岸线的动态监测具有独特的优势。通过对多源遥感影像数据进行挖掘，对1991—2013年岸线变化情况进行研究，解译出5个时相的海南岛南部海岸线，统计了岸线变化趋势，并分析了典型区岸线变化原因。研究表明：从总体上看，岸线总长度在1991—2013年间变化不大，在560～600 km之间，波动很小；但局部岸线变化比较大，主要是随着城市建设的发展而围海造地、码头建设以及鱼塘围垦所引起的。
Abstract:Coastal zone, the interaction zone between land and sea, is the most active and economically developed area on the earth. It, however, is also a region with fragile ecological environment and relatively limited carrying capacity of resources and environment. The study of the variation of the coastline is of great significance to the development and protection of coastal resources. Remote sensing technology, which is macroscopic and fast, has unique advantages for repetitive observation of an area. It does not need long-term investigations in waters and surface conditions; compared with the traditional methods. The remote sensing monitoring of coastline changes is cost saving, and may bring forward high economic and social benefits. According to the multi-source remote sensing image data, we discovered four periods of coastline around the Southern Hainan Island. The change trend and origin are also studied. It is found that little of the total length has been changed in the years from 1991 to 2013. It fluctuated between 560 km and 600 km, and in fact, is very small. However, from a local point of view, the change in coastline length may be relatively large due to land reclamation, coastal construction and urban growth.
