摘　　要：针对当前存在的空间冲突、尺度划分失真、功能错位等土地资源利用所面临的问题,本文以山水林田湖草沙生命共同体理念为指导,通过归纳与演绎分析,探索性提出了土地空间连续体概念,并从概念辨析、哲学解释、分类学解释等方面开展了内涵解析。依托主导因素分析、DEM流域分析、图层叠加空间分析等方法建立了土地空间连续体尺度划分理论框架。结果表明:①土地空间连续体概念能够从土地系统科学视角全方面、多尺度表达土地单元组合体内涵,科学诠释了土地构成单元在空间上连续与间断的辩证关系。②以小流域、土壤、植被、土地现状利用方式为主导要素将阜平县土地空间连续体逐级划分为“小流域尺度−土地链尺度−土地段尺度−土地块尺度”4级尺度类型体系,其中一级小流域尺度包含7种类型单元,二级土地链尺度包含54种类型单元,三级土地段尺度包含140种类型单元,四级土地块尺度包含560种类型单元,为土地空间多尺度开发利用提供了理论与方法借鉴。③土地空间连续体各级尺度类型是从土地单元空间连续的视角考虑了多种主导因素的影响,是一种综合反映环境和土地系统特点的基本研究单元。研究成果可为后续开展特征尺度视角下的土地利用与评价研究提供新的思路和方法。In response to the current spatial conflicts,distorted scale division,and functional misalignment in land use.This article is guided by the concept of a life community of mountains,rivers,forests,fields,lakes,grasses,and sands.Through induction and deductive analysis,the concept of Land Spatial Continuity(LSC)is tentatively proposed,and connotation analysis is carried out from the perspectives of concept differentiation,philosophical interpretation,and taxonomic interpretation.A theoretical framework for LSC scale division has been established based on methods such as dominant factor analysis,DEM watershed analysis,and layer overlay spatial analysis,providing theoretical and methodological references for multi-scale development and utilization of land space.The results indicate that:1)The concept of LSC can comprehensively and multi-scale express the connotation of land unit combination from the perspective of land system science,scientifically interpreting the dialectical relationship between continuous and discontinuous land constituent units in space.2)Taking small watersheds,soil,vegetation,and land use status as the main elements,the LSC in Fuping County is divided into a four level scale type system of“small watersheds scale-land chain scale-land segment scale-land block scale”.The first level small watersheds scale includes 7 type units,the second level land chain scale includes 54 type units,and the third level land segment scale includes 140 type units,The fourth level land block scale includes 560 types of units,provided theoretical and methodological references for multi-scale development and utilization of land space.3)The various scale types of LSC consider the influence of various dominant factors from the perspective of land unit spatial continuity,and the analysis results are closer to actual observation values.It is a basic research unit that comprehensively reflects the characteristics of the environment and land system.The research results can provide ideas and methods for subsequent resear
