福建省海岛土地利用特征及变化分析

福建省908专项海岛土地利用调查对全省l321个面积在500m。以上海岛的土地利用类型与分布进行了调查统计，将土地资源划分为12个一级类，采取多源信息相互印证及3s结合的工作方法，基本查明了海岛土地分布范围、面积和开发利用现状．经调查与测算，福建省海岛土地总面积为1628389432m^2。（包含海岛岸线外侧沿海滩涂面积474076929m^2），即海岛陆域土地总面积为1154312503m^2，其中有居民海岛陆域土地面积1106414004m^2，无居民海岛陆域土地面积47898499m^2．与1988年福建省海岛调查的14个海岛的土地利用调查结果进行对比并分析变化的原因．

Land use Pattern and Its Changing Characteristics on Islands of Fujian Province

Abstract： Land use types and spatial distribution of the 1 321 islands with area above 500m^2 are investigated, which is a task in the so-called 908 project in Fujian province. In the investigation, is- land land resources are divided intol2 primary categories. Taking multi-source information for verifica- tion and the combination of 3S＇ methods, these islands＇ land use distribution, area and current situa- tion of development are studied. By the survey and calculation, the area of islands in Fujian province totals 1 628 389 432 m^2, including 474 076 929 m^2 of beach area. And within the rest 1 154 312 503 m2 land area, the area that has residents is 1 106 414 004 m^2, and that without residents reaches 47 898 499 m^2. The survey vey, which only included 14 results in the 908 project are further compared with those in the 1988 sur- islands, and an analysis of changing land use is presented.
