摘要: 为了评价安徽省城市空间吸引力的影响范围,本文利用Voronoi图的空间剖分特性,结合主客观综合赋权法,提出了运用组合权计算中心性强度,将其作为权重引入模型,建立安徽省城市加权Voronoi图,与周长-面积分形理论和新一线城市研究所2019年发布的新一线城市排名作对比分析,分析了安徽省城市的空间吸引力影响范围。经分析验证,建立的组合权Voronoi图能够有效地对安徽省城市的吸引力影响范围进行评价。此外对城市等级的划分,也提供了借鉴和参考。

关键词: 组合权Voronoi图, 城市空间吸引力影响范围, 周长-面积分形理论, 城市排名, 对比分析

Abstract: In order to evaluate the influence range of prefecture-level cities in Anhui province, this study uses the spatial dissection characteristics of Voronoi diagrams and the combination of subjective and objective comprehensive weighting methods, and proposes the use of combined weights to calculate the central intensity, which is used as a weight to introduce models to establish Anhui province. The city-weighted Voronoi diagram is analyzed in association with the perimeter-area fractal theory and the ranking of new first-tier cities published by the New First-Line City Institute to analyze the spatial impact of prefecture-level cities in Anhui province. After analysis and verification, the established combination of Voronoi diagram can effectively evaluate the influence range of prefecture-level cities in Anhui province. In addition, it also provides reference for the classification of city grades.

Key words: combination weight Voronoi diagram, urban space attraction range, perimeter-area fractal theory, city ranking, comparative analysis
