摘　　要：以大长山岛为研究区,解译2003-2018年的遥感影像,运用土地利用转移矩阵、土地利用综合指数、价值当量因子等方法,分析土地利用及其生态系统服务价值的变化特征。结果表明:(1)研究期内,大长山岛土地利用以林地和耕地为主,且二者面积呈减少趋势;其他地类面积呈增加趋势,其中草地和建设用地增幅最大;建设用地主要转入来源是耕地。(2)2003-2018年,大长山岛生态系统服务总价值呈波动减少态势,从2785.71万元减少到2472.65万元,变化率为-11.24%;林地对ESV贡献最大,比重约占48.5%;单项ESV减少最多的是气体调节,减少了65.69万元。(3)各土地利用类型价值系数的敏感性指数都小于1,研究结果有一定的参考性。Taking Dachangshan Island as the study area,this paper interprets remote sensing images from 2003 to 2018,and analyzes the change characteristics of land use and its ecosystem service value by using land use transfer matrix,land use comprehensive index,value equivalent factor and other methods.The results showed that:(1)During the study period,the land use of Dachangshan Island was mainly forest land and cultivated land,and the areas of both of them showed a decreasing trend;The area of other land types increased,among which grassland and construction land increased the most.The main source of construction land transfer is arable land.(2)From 2003 to 2018,the total value of ecosystem services on Dachangshan Island decreased from 27,857 million yuan to 24,726 million yuan,with a change rate of-11.24%;Forestland contributed the most to ESV,accounting for about 48.5%.The largest reduction in individual ESV was in gas regulation,with a reduction of 656,900 yuan.(3)The sensitivity index of value coefficient of each land use type is less than 1,and the research results have certain reference value.
