摘　　要：中心地理论研究是城市群和城市化的基础理论之一。基于Voronoi图的几何结构特征和邻域空间分析能力,提出一种构建中心地等级体系的方法。将此方法应用于中国大陆城市的肯德基餐厅网点分析,构建出中国大陆城市的肯德基中心地等级体系。研究结果表明,KFC等级中每一个低一级中心地数量都近似为高一级中心地数量的3倍;在不同的地理区域范围内,同一级中心地规模可能存在很大差异,甚至低等级中心地规模可以超过高一级中心地。Center place theory is one of the fundamental theories of urban clusters and urbanization.One method of building center place hierarchy is proposed in this paper based on the geometrical features and spatial neighboring analysis function of Voronoi diagram.By applying this method to analysis of the China motherland's KFC outlets,we build the center place hierarchy for those cities KFC.The result shows that,the lower level center palace is just almost three times more than the higher level center palace in KFC hierarchy,and the scale of two same level center place may be greatly different or the scale of the lower level center place is bigger than the higher center place.
