摘　　要：以多年平均高潮线向陆一侧延伸2km的陆域部分作为研究范围,分析和评价了海南岛海岸带土地利用状况及问题。结果表明:1)海南岛12个沿海市县位于2km宽度海岸带内的土地资源共计228166.44hm2,约占全省土地总面积的6.63%;2)文昌市海岸带土地面积及农用地面积均居全省首位,但海岸带建设用地面积最大的为三亚市,其次是海口市;3)海岸带是全省建设用地分布最密集的地带,其建设用地平均密度约为全省的4.5倍;4)海岸带土地利用率高,但人地矛盾突出,土地利用结构尚待优化;5)海岸带土地利用已引起部分地段的生态环境明显退化,这在文昌、万宁与海口3市表现尤为突出。针对这些问题,文章最后从海岸带土地利用程度、利用结构、利用方式、空间布局和开发效益5个方面提出了应对措施或建议。In this paper the coastal zone to be studied is defined as the area along the shoreline at mean high tide level with a width of 2 km. The present situation of land use of the coastal zone and its problems are analyzed. The results show that：1） there are 228 166.44 hm2 of land resources in 12 coastal cities and counties, accounting for 6.63% of the total of the province; 2） both coastal land area and the farmland area in Wenchang rank first on the list of the 12 coastal cities and counties,while Sanya has the largest construction land area in coastal zone,Haikou the second; 3） the density of the construction land in coastal zone is high,which is 4.5 times the average of the province; 4） the land utilization efficiency of coastal zone is high,but contradiction between man and land becomes more and more prominent.And the land use structure needs to be optimized; 5） the intensive land use of coastal zone has led to obviously ecological degeneration, and this is particularly prominent in Wenchang,Wanning and Haikou.Aiming at those problems,the paper brings forward some countermeasures or suggestions for coastal zone on land use manner,land use degree,land use structure,land use distribution and land use benefit.
