基于加权Voronoi图的县级城镇经济区划分研究

Delimitation of town economic zones at county scale based on weighted-Voronoi diagram

县级城镇经济区的划分可为城乡统筹发展提供决策依据。本文通过构建中心城镇综合实力评价指标体系,运用主成分分析法测算各中心城镇中心性强度,基于城市扩展断裂点理论,利用加权Voronoi图生态各中心城镇综合影响力范围,并依据各中心城镇综合影响力划分各经济区。

Delimitation of town economic zones at county scale can provide a scientific decision-making basis for urban and rural development. By establishing the factors system for comprehensive evaluation of each central town, the central-strength is calculated by using principal component analysis. And the central towns influenced region is divided with help of weighted-Voronoi diagram based on the breakpoint theory, and then the town economic zones is delimitated according to the influenced region.
