摘　　要：运用景观生态学的理论和方法,以平潭综合实验区主岛陆相区域为研究对象,利用1996年、2002年、2008年3个时相遥感影像为主要数据源,分析了与防护林关系密切的土地利用类型的景观格局指数,以期为平潭防护林乃至区域生态建设提供参考依据。结果表明:研究区景观格局呈现进一步破碎的趋势,与平潭经济社会发展的趋势一致;建筑用地、农用地等与林地关系密切的土地利用方式各项景观格局指数变化较强烈。最后从维护海岛生态安全的角度提出了4点建议。Using the theory & method of landscape ecology ,continental area on main Pingtan Island of Comprehen‐sive experimental zone were taken as research objects .Taking three remote sensing images in the year of 1996 , 2002 ,2008 as the main data sources ,indices of landscape pattern for land use which are close to protection forest were analyzed ,so as to provide reference for Pingtan shelterbelts and even regional ecological construction .Three re‐mote sensing images were adopted to obtain the landscape indexes so as to analyse to possible relationship between coastal protection forest and the main land‐use of coastal area .Result shows that the landscape pattern of research area showing the trend of broken;the dynamics of the landscape indexes were consistent with the development tend‐ency of the economic society .Index variation of each landscape pattern building land ,farmland and other land uses which have close relationship with forestland are stronger .Finally ,four advices were given from the perspective of maintaining ecological safety island .
