摘    要:为了给区域城镇体系规模等级结构研究提供更好的理论依据,文章以中心地理论为基础,借助分形理论构建了一般的城镇等级—规模分布模型。在已知城镇规模分布分维数的条件下,可以计算出在不同的中心地模型中所谓值下,区域城镇体系等级—规模的分布序列,并称其为中心地分布模型。与Zipf公式相比,上述模型不仅更具理论内涵、更接近实际,而且具有横向可比性和纵向预见性,还可以确定区域城镇体系规模分布的中心性值,为城镇体系发展提供更好的导向。最后以陕西省关中平原为例说明了此模型在实际中的应用。

关 键 词:城镇体系  分形理论  等级规模  中心地分布模型

Abstract:The Center Place Theory and the Rank-Size Rule is two classical theories of urban geography science.The Zipf's law is the important practical formula to describe the Rank-Size Rule,but there are some questions when the Zipf's formula is used to learn a urban system's size distribution,such as the practical discussions are more than the theoretical studies and the theoretical values of the cities' sizes resulted from the Zipf's formula are far different from the practical values.In order to make the Rank-Size study of regional urban system has better theoretical dependence;this article sets up a model of urban system's Rank-Size,which is resorted fractal theory on the basis of Central Place Theory.If the fractal dimension of the urban system's sizes distribution is known,the urban system's Rank-Size distribution model on the basis of Center Place Theory could be made up for a single region,and the author call it Center Distributed Model.Compared with the Zipf's formula,above model has better theoretic values and practical worth.First,it adds more theoretical mean into Rank-Size Rule;second,it can predict the Rank-Size distribution of one region's urban system and also makes it can be compared with other regions' urban system;third but not the last,it can estimate the value of "K" which is defined in Center Place Model.So above model is a better orientation for the development of a region's urban system.At last,the author takes the GuanZhong area in Shaanxi province for an example to explain the application of above model.
Keywords:urban system  fractal theory  Rank-Size
