摘要:

了解海岸线变化对海岸资源的开发与保护有着重要的意义。论文基于遥感技术与GIS技术,提取了海南岛1980、1990、2000、2010年4个时期的海岸线,并对其30 a来的时空变化特征进行了系统分析。结果表明:海南岛海岸线变化主要受人为因素的影响,近30 a来其长度增加了55.4 km;海岸线时空变化显著,变化比较剧烈的岸段多分布在地势较为平缓的南部地区,以养殖开发、工业用地、城镇与港口建设用地为主。研究认为,海南岛海岸线的变化,将有可能导致诸如岸线侵蚀等环境问题,应注意合理开发,利用海岸线资源。

Abstract:

Understanding of changes of coastline has significance in developing and protecting coastal resources. In this paper, based on the technology of GIS and RS, coastlines in the year of 1980, 1990, 2000 and 2010 of Hainan Island were interpreted from remote sensing images using baseline method. The analysis of spatial and temporal changes of coastlines and the driving forces shows that: Hainan Island coastline changes are mainly affected by human factors; the total length of the coastline had increased by 55.4 km in the past 30 years, which is evidently in the changes of artificial coastline; and the temporal and spatial variation that is mainly reflected in aquaculture reclamation, industrial land use, town and port construction, was significant, especially in southern region where is relatively flat. These results imply that the changes of Hainan Island might lead to a set of environment problems such as coastline erosion, and it is really particularly important to develop coastlines and use the coastal resources reasonably.

Key words: photogrammetry and remote sensing, coastline changes, baseline method, Hainan Island
