Construction of public service facilities layout network in pastoral areas based on psychological cognition range information - a case study of Inner Mongolia pastoral areas of East Wuzhumuqin Banner in Xilingol

摘要

The settlements in pastoral areas have the spatial distribution characteristics of “broad scattering and small agglomeration”. The extension of range makes their physical information attributes change into a spatial awareness with psychological information attributes. In this paper, the psychological cognitive range in herdsmen’s spatial awareness was taken as the basis for establishing a spatial network and the social network analysis method was used to quantitatively study the spatial network relationship of settlements and the layout of public service facilities in pastoral areas of Inner Mongolia. The results show that the construction of control equilibrium point of interaction between spatial characteristics of settlements and public service facilities in pastoral areas can be rebuilt by using 10 km psychological cognitive range information; the zoning characteristics of spatial settlement network constructed on the basis of Pajek social network and ArcGIS spatial analysis are obvious; It is of great theoretical and practical significance for pastoral areas and low population density areas to take the index of network node degree as the basis of constructing dynamic layer layouts of public service facilities network and to establish “spatial Network + dynamic layout” layer model of public service facilities layout according to the characteristics of spatial network zoning.
