摘　　要：京津风沙源区治理工程是国家为改善和优化京津及周边地区生态环境状况、减轻风沙危害实施的一项重大生态建设工程.工程实施以来,区域的土地利用、植被盖度、土壤风蚀等方面发生了深刻变化,也改变了区域生态系统服务的供给.生态系统服务及其多功能性的理论框架与定量化研究,为综合评估区域生态效益,准确厘定生态系统服务变化,深刻理解生态治理工程对区域生态系统服务的作用与影响提供了方法和途径.本文利用多源数据,从生态供给、生态调节、生境支持服务3个方面,计算了京津风沙源区生态系统服务各项指标,结合生态系统服务集成性指数(multiple ecosystem services landscape index,MESLI)和生态系统服务香农多样性指数(ecosystem services Shannon diversity index,ESHDI)等指标,评估了县域的生态系统服务多功能性,揭示了县域尺度综合生态服务的空间格局和集聚规律,阐明治理前后生态系统服务的变化特征及其空间分布,确定各类土地利用和生态系统服务的相关关系,厘清风沙治理与植被恢复工程对区域生态系统服务功能及其多功能性贡献的变化,并对治理区2000~2015年的生态系统调节服务进行了价值核算,为京津风沙源治理工程效益定量评估和国家制定新的治理规划提供科学依据.The Beijing-Tianjin sandstorm source control project(BTSSCP)is a large and famous ecological construction project with enormous investment that aims to improve and optimize the ecological condition of Beijing-Tianjin and the surrounding areas.Since the implementation of the BTSSCP in 2000,profound changes have occurred in the region regarding land use,vegetation cover,soil,wind and water erosion,and the supply of regional ecosystem services(ESs).Changes in regional ESs are influenced not only by human activities but also by natural factors such as climate change.Distinguishing and quantifying the roles of climate change and land-use change on regional ES changes can better serve sustainable land-use management decisions at the regional and national levels.Additionally,information is needed on the economic benefits caused by sandstorm control and ecological restoration,such as the value change of the regulating ESs since the BTSSCP began,the variation in the spatial patterns of ESs and their integration,and the contribution of sand control and vegetation restoration to regional ES changes.Moreover,a landscape-level ES multifunctionality concept and measurement framework provided deep insight into the spatial supply-benefit relationship of ESs,and this information is crucial for sustainable ecosystem management and land-use planning.In this study,a set of ES indicators that represent ecological provisioning(n=2),regulating(n=4),and supporting(n=2)services at the county scale in the BTSSCP were calculated based on a field survey,Normalized difference vegetation index(NDVI)data,land-use data,meteorological data(i.e.,temperature,precipitation,wind speed,and direction)and socioeconomic census data.Then,the ES multifunctionality of each county was assessed using the multiple ES landscape index(MESLI)and the ES Shannon diversity index(ESHDI).Variation partitioning was used to distinguish the contributions of land-use area composition and major climatic conditions(annual average temperature,annual precipitation,and averag
