摘　　要：【目的】探明杭州乡村地区因土地利用/覆被剧烈变化所带来的风险与压力,挖掘乡村景观格局对生态系统服务供给的空间影响,是快速城市化背景下对乡村生态系统进行管理和规划的基础。【方法】在评估杭州乡村地区生态系统服务与量化景观格局指数的基础上,应用3种回归模型定量分析景观格局对生态系统服务供给的影响。【结果】1)生态系统服务功能与土地利用类型密切相关;2)景观空间格局总体趋于破碎化和均匀化,平原地区最为显著;3)乡村景观格局对不同生态系统服务的影响存在空间异质性,在景观格局指标与程度两方面均有体现,其中,地形坡度(SLOPE)对服务的影响最为显著,表现出很强的正相关关系,其次是景观面积(TA)、香农均匀度指数(SHEI)、边缘密度(ED)、蔓延度指数(CONTAG)。【结论】分析乡村地区景观格局对生态系统服务供给的多尺度空间异质性影响,可为乡村景观规划与管理提供理论依据,从而促进乡村生态系统服务的可持续管理。[Objective]Changes in landscape pattern often bring about alterations in the structure,process,and function of ecosystem.In the context of rapid urbanization,drastic changes in land use/land cover(LULC)significantly disturb the structure and function of rural landscapes,leading to a series of ecological and environmental issues in rural areas such as farmland transformation,landscape fragmentation,and habitat degradation.These issues,in turn,pose threats to the stability of ecosystem.Therefore,understanding the impact of rural landscape pattern on ecosystem service provision is fundamental for managing and planning rural ecosystem under rapid urbanization.In light of this,this research takes Hangzhou as an example to reveal the relationship between rural landscape pattern and ecosystem service under rapid urbanization,in hope of providing a reference value for local decision-makers in terms of land use,and a basis for planning and layout in the central and western regions of China that are about to undergo urbanization.[Methods]This research focuses on a typical area undergoing rapid urbanization—the rural area of Hangzhou,Zhejiang Province.This area has experienced dramatic changes in land use/land cover over the past 20 years,resulting in significant ecological issues such as habitat degradation and landscape fragmentation.The research employs models such as InVEST and Fragstats to assess ecosystem services(including food production,water yield,carbon sequestration,habitat support,soil conservation,and cultural services)in relation to rural landscape patterns.Spatial relationships between ecosystem service provision and rural landscape pattern within the research area are identified using OLS(ordinary least squares),GWR(geographically weighted regression),and MGWR(multiscale geographically weighted regression)models.Additionally,the performance of the MGWR model is compared with other global or local regression models.[Results]1)The spatial pattern of ecosystem service function in the rural area of Hangzhou i
