摘　　要：运用分形理论,对赣州市城镇体系的规模分布和空间结构的分形特征进行了实证分析,得到以下结论:(1)在城镇规模分布方面,中等位序的城市较多,人口分布比较均衡,认为是一种较低水平的均衡;(2)在城镇空间结构方面,城镇空间分布呈现出集聚性特征,城镇的空间关联程度不够紧密,空间相互作用强度不大。在上述结论的基础上对赣州市城镇体系建设提出了建议。Fractal study is one of the most important content in modem theoretic geography, and the urban system of the urban system fractal theory and tries to find the rule of the urban system in mountainous area. Based on the fractal theory, the paper analyzes the scale structure and spatial structure of urban system in Ganzhou, and finds out that the urban system in Ganzhou have the fractal properties, so the paper thinks that fractal theory can fit to calculate and analyze the scale structure and spatial structure of urban system in mountainous area. According to the results of calculation and analysis, the paper draws the conclusions below： （ 1 ） The quantities of middle scale city are more than bigger and smaller one, and the regional population distribution is equilibriums relatively. （2） The degree of interspaces conjunction between the cities is inadequate compactness, and the intensity of the interaction of the cities is medium. According to the conclusions mentioned above, the paper presents that the effective measures must be taken to improve the situation of the urban system structure in Ganzhou. The Ganzhou government should centralize the whole resources to construct regional center city and some county city with finer condition, and should improve the communication conditions to boost up the spatial interaction intensity.
