摘　　要：在GIS技术支持下,利用分形方法和断裂点模型对湖北省城市体系空间结构进行定量测度和空间的次级划分,并对其形成演变规律进行时空分析和优化提升。研究显示:(1)该省城市分布密度较大,且区域人口分布与城市分布基本一致。(2)城市体系空间结构的类型现状正处于集聚型,城市空间分布有着"沿路、沿江、沿线"的三沿特点,次级城市体系的空间结构变化类型有着向均匀型演变的趋势。(3)城市体系空间结构变化正处于初步网络化阶段,大中城市向心集聚和扩散2种力量基本均衡,城市总体空间分布有着"沿江"的一元性向"三沿"的多元性演化的趋势。最后,基于上述研究,对其城市体系空间结构发展提出了优化思路。The spatial structure of urban system in Hubei Province has been measured by fractal method and GIS technique, and the whole urban system has been divided into four sub-urban system by use of Breaking Point Model. On the basis of that, the rule of the evolution of the spatial structure of the urban system has also been deduced. The results show ： Firstly, there is higher distribution density of cities, and the distribution of population is similar to that of cities; Secondly, the types of the spatial structure of the urban system are agglomerative in which the distribution of cities is along roads, rivers and transport lines, and there exist a tendency of uniform distribution for the evolution of the urban systems ; Thirdly, the changing of the spatial structure of the urban system is a network stage, where there exist an equilibrium between concentric forces of major cities and eccentric strength of small cities, meanwhile, there exist a dispersive tendency for spatial distribution of the cities from along alone lines to along three-following. At last, according to the results and the urbanization planning in Hubei Province, the paper has put forward the optimum ideals of the spatial structure of urban system.
