研究目的：对海南岛沿海12个市（县）海岸带区域开展基于防护功能重要性的土地生态安全综合评价，揭示区域土地生态安全差异及其主要影响因素。研究方法：运用RS、GIS技术进行定量化综合评价，并计算各市（县）的区域土地生态安全指数。研究结果：海南岛海岸带土地生态安全等级可划分为高安全、较安全、一般安全、较不安全及不安全5个等级，其中一般安全及以上水平区域面积比例达81.8%，安全等级较低的区域主要分布在开发强度和规模较大的东部以及新兴工业开发区。研究结论：海南岛海岸带土地生态安全总体状况良好，安全等级较低的区域主要因地产、旅游基础设施及农业养殖业等改变海岸带自然景观结构和生态功能。不合理的区域土地资源开发利用导致防护林生态系统、湿地生态系统破坏进而威胁海岸带土地生态安全。

The purpose of this paper is to assess the land ecological security in the coastal zone of Hainan island in terms of the importance of ecological protection, and to reveal the differences and main influential factors. The methods include using RS and spatial analysis of GIS to complete the general assessment, and then calculating the region ecological security index. The results show that the general condition of ecological security in the coastal zone of Hainan island was at medium level, and 81.8%of areas were beyond medium. The poor situation zones were in the eastern coast and some new industrial parks, where the regional development were intensive and extensive. The paper concludes that the general condition on land ecological security is fine. The poor performance in some area was caused by the aquaculture industry development, real estate and infrastructure establishment. The unreasonable land resource utilization led to the shelter belt and wetland ecosystem destruction, which further harmed the land ecological security in coastal zone.
