Abstract:

This article realizes the classification of urban system structure and the division of economic zone in Horqin by improving the breaking point model based on spatial interaction model and GIS platform. First of all, it introduces a model improving method which replaces the urban population with the centrality strength and combines the weighted Voronoi Diagram. Then it builds and completes the centrality strength computing index system by introducing the concepts of weighted average distance friction index of towns and cost weighted distance, etc. The urban system structure has been classified into central towns, secondary central towns and common towns. Finally, by comparing two space division solutions of regular Voronoi diagram and weighted Voronoi Diagram, it can be found that the latter has been determined to be the final solution of urban influenced regions. By merging and searching the sub-regions step by step, this article divides the study area into three economic zones—east economic zone, middle economic zone and west economic zone. The results reflect the current situation and the tendency of development of urban system and provide theoretical basis for the sustainable development of urban system in Horqin Left Middle Banner.

Key words: spatial Interaction model, system structure planning, economic function zoning, Voronoi diagram
