摘要
[目的]以“文化型”“朝圣型”“旅游型”海岛—湄洲岛为研究对象,分析2000—2020年海岛开发建设过程生态系统服务价值(ESV)的时空变化特征,为制定湄洲岛旅游区土地利用规划和生态建设提供科学参考。[方法]以覆盖湄洲岛的1985—2020年全球30 m精细地表覆盖动态监测数据为数据源,采用ArcGIS技术提取研究区2000,2005,2010,2015和2020年5期土地利用数据,通过土地动态度、土地利用转移矩阵和生态贡献率分析20 a间湄洲岛土地利用变化特征,并结合当量因子法估算湄洲岛生态系统服务价值(ESV)。[结果]①2000—2020年,湄洲岛土地利用类型以建设用地和耕地为主,面积变化上主要表现为建设用地和湿地面积的增长,耕地和林地面积的减少;土地利用转移以林地—耕地—建设用地—水域之间的相互流转和建设用地对耕地和林地的侵占为主;②研究期限内湄洲岛ESV大幅下降,20 a内减少了1252.69万元,林地和耕地是湄洲岛ESV的主要贡献因子,湿地和水域面积增加是ESV增加的主要影响因素;③各单项生态系统服务价值主要表现为:调节服务>支持服务>供给服务>文化服务;④ESV空间分布呈中间低、四周高的特征,高值区与域内森林覆盖率高的区域高度重叠,低值区主要分布在建设用地。[结论]林地和耕地是湄洲岛ESV的主要贡献因子,调节服务对湄洲岛生态系统服务价值量贡献最高。因此在开发建设过程中应提高建设用地利用效率,加强对耕地和林地保护。
[Objective]The spatiotemporal changes of ecosystem service value(ESV)during the development and construction of Meizhou Island(a‘cultural’,‘pilgrimage’,and‘tourism’island)during 2000—2020 were analyzed in order to provide a scientific reference for the formulation of land use planning and ecological construction for the tourism area of the island.[Methods]The global 30 m fine land cover dynamic monitoring data covering Meizhou Island from 1985 to 2020 were used as the data source,and ArcGIS technology was used to extract the land use data for 2000,2005,2010,2015,and 2020 in the study area.The land use changes on Meizhou Island during the recent 20 years was revealed through land use dynamics,land use transfer matrix,and ecological contribution rate.The value equivalent method was used to estimate ESV for Meizhou Island.[Results]①From 2000—2020,the land use types on Meizhou Island were mainly construction land and cultivated land.Land use area changes were mainly manifested as increases in construction land and wetland,and decreases in cultivated land and forest land.The land use transfer was reflected in the mutual flow among forest land-cultivated land-construction land-water area,and the encroachment of construction land on cultivated land and forest land;②During the study period,the ESV of Meizhou Island decreased by 12.5269 million yuan,of which forest land and cultivated land were the main contributing factors of ESV for Meizhou Island.The increases of wetland and water area were the main influencing factors of the increase of ESV;③The values of each individual ecosystem service function followed the order of regulation service>support service>supply service>cultural service;④The spatial distribution of ESV showed a pattern of‘lower in the middle and higher on the periphery’,and the distribution of high value areas overlapped highly with that of forest land.Low ESV areas were concentrated in the construction land.[Conclusion]Forest and cultivated land were the main contributors of
