| 摘 要： | 确定中心城市的影响范围对城市规划与城市经济区划具有重要意义.通过选取反应城市影响范围的综合指标体系,运用主成份分析及数据变换的方法,确定了安徽省地级中心城市的强度,将城市断裂点理论与加权Voronoi图相结合,实现了对各中心城市空间影响范围的界定和生成.依据安徽省政府提出的"两带三片"区划理论,结合划分的城市影响范围,将17个城市的不同影响区域进行合并,确定了安徽省五个大区的具体覆盖区域.

| Abstract: | This paper selects the integrative indices reflecting influential city regions and calculates the influencing regions of cities in Anhui Province through Principal Analysis and data transformation with the help of the SPSS software.By integrating the Breaking Point Theory with Additively Weighted Voronoi Diagram,the paper delimits and presents the influencing regions of the central cities using the ARC/INFO and ARCVIEW geographic information system software.The resulting analysis provides the delimited regions of influence necessary for central government zonal planning which divide the province into five areas according to "Two Zones Three Areas" project planned by Anhui government. |
