摘　　要：岛群是中国近岸海岛的典型存在形式,开展岛群及其内部海岛之间的景观格局演变研究可为海岛资源管理提供理论依据和技术支撑。基于洞头区六个有居民海岛(洞头岛、半屏岛、大三盘岛、花岗岛、霓屿岛和状元岙岛)2008年、2014年、2018年和2022年4期的高分辨率遥感影像,计算了岛群和单个海岛的景观格局指数。结果表明:1)研究期间岛群景观中林地、水域、耕地面积占比呈持续下降趋势,建筑用地、工矿用地、道路面积占比持续上升。2)洞头岛、大三盘岛、霓屿岛和状元岙岛的景观格局变化幅度大,前两者以建筑用地增加为主,后两者以工矿用地增加为主;半屏岛和花岗岛的景观格局相对稳定。3)各海岛间的开发活动相互关联,景观有序演变,霓屿岛和大三盘岛的林地变为采矿区,支持了洞头岛、状元岙岛水域的围填和后续的开发建设;随着大岛的建设和发展,周边小岛的发展也开始起步。Island group is a typical form of existence for offshore islands in China.Investigating the evolution of landscape patterns in an island group and among individual islands can provide theoretical foundations and technical support for island resource management.Based on the high-resolution remote sensing images of six inhabited islands(Dongtou Island,Banping Island,Dasanpan Island,Huagang Island,Niyu Island and Zhuangyuanao Island)in Dongtou District in 2008,2014,2018 and 2022,the landscape pattern indices of island groups and individual islands were calculated.The results indicate the following:(1)During the study period,the proportions of forest land,water areas,and cultivated land in the landscape of island group have been continuously declining,while the proportions of building land,industrial and mining land,and road areas have been steadily increasing.(2)The landscape pattern changes on Dongtou Island,Dasanpan Island,Niyu Island,and Zhuangyuanao Island are significant,with the former two primarily characterized by an increase in building land and the latter two by an increase in industrial and mining land;the landscape patterns of Banping Island and Huagang Island are relatively stable.(3)Development activities among the islands are interrelated,with the landscape evolving in an orderly manner.The transformations of forest land into mining areas on Niyu Island and Dasanpan Island have supported the reclamation and subsequent development of water areas on Dongtou Island and Zhuangyuanao Island;as the larger islands develop,the development of surrounding smaller islands has also begun.
