Preliminary exploration of connotation and scale division of land spatial continuum:Taking Fuping County as an example
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 over-lay spatial analysis,providing theoretical and methodological references for multi-scale development and utiliz-ation of land space.The results indicate that:1)The concept of LSC can comprehensively and multi-scale ex-press the connotation of land unit combination from the perspective of land system science,scientifically inter-preting 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 actu-al observation values.It is a basic research unit that comprehensively reflects the characteristics of the environ-ment and land system.The research results can provide ideas and methods for subsequent research on land use and evaluation from the perspective of feature scale.
