摘　　要：土地功能是土地本身所特有的能力,基于土地作用视角下土地功能的分类进行研究,有利于明确区域发展基础及发展潜力。厘清土地多功能权衡/协同关系,是实现土地多功能协同开发,推动区域土地资源高效利用的关键。该研究基于土地作用视角下土地功能的分类,以河北省阜平县为研究区,采用空间分析和相关性分析等方法,从村域尺度出发,对阜平县土地多功能进行评价、空间可视化以及相关性分析。结果表明:阜平县土地各功能在空间分布上存在着不同规律;阜平县土地多功能在总量上和结构上存在相反的空间分布格局,阜平县土地各功能间的协同程度较低;村域视角下的阜平县土地多功能权衡/协同研究,6种功能的15种两两组合中仅有生态功能和原材料供给功能之间存在权衡关系,其余均为协同关系,其中景观功能和支撑功能间的协同作用最为显著,两种功能间的相关系数为0.643 1。该研究进一步完善了土地多功能研究体系,为阜平县土地资源高效利用和管理策略的制定提供了参考依据,同时,相关研究结果也可为土地资源管理领域提供参考。Multiple land functions and services can be conducive to humans and sustain the ecosystem.A land function can be classified to clarify the basis of regional development and potential under the perspective of land role.The multifunctional use of land can represent an effective strategy to deal with the scarcity of land resources.Their overall value can be enhanced to examine the spatial distribution pattern of multifunctional land use.Furthermore,the multifunctional trade-offs and synergistic relationships among land use facilitates can also contribute to the configuration and layout of territorial spatial planning.Taking Fuping County of Hebei Province as the study area,the land function was classified to explore the spatial patterns and tradeoffs/synergy under the perspective of land role.The resource allocation and actual situation were combined to optimize the land element factors,as the evaluation indexes.The evaluation index system was then constructed to quantify the multifunctionality of land use.Two approaches were employed to assess the land multifunctionality,including the weighted composite index and Simpson's inverse index.Furthermore,Pearson's correlation analysis and bivariate local Moran's index were utilized to examine the quantitative relationship and spatial correlation of multifunctional land use.The results show that:(1) The spatial distribution of land function was subjected to the natural influencing factors on a variety of patterns.(2) Contrasting patterns were found in the spatial distribution of land multifunctionality,in terms of the total volume and structure.There was also a low level of structural synergy among land functions within the county.In terms of the total volume,the multi-functionality of land exhibited an overall spatial distribution pattern of “low in the center and gradually increasing towards the north and south”.In structural features,the multi-functionality of land was characterized by the spatial distribution pattern of “high in the center,gradually decreasing t
