摘　　要： 采用全国县城所在的建制镇与所有设市城市数据,以省区作为基本研究单元,运用最近邻分析与种群分布理论定量分析了2009年城市体系空间分布的省际差异及其影响因素。研究表明:2009年我国各省区的城市空间分布格局以均匀分布为主,明显表现出集聚分布的仅有西藏、青海和新疆三省;通过对中国各省区城市分布与自然、社会经济条件进行回归分析发现,各省区城市的空间分布模式与自然及社会经济因素具有较强的相关性;从各变量的重要性来看,影响区域城市空间分布形态最主要的因素是路网密度,其次分别是复种指数、人均耕地面积、土地垦殖率与城市化率;城市在发展的过程中,为了获得足够的要素维持自身生长,各城市必定会最大化地攫取要素资源,导致了城市之间的资源竞争;区域内城市的外部环境越趋于均匀,城市的空间分布越趋于均匀,而区域内城市外部环境分布不均则导致城市表现出集聚分布模式;在其他影响因素不变的情况下,复种指数与城市化水平的提高在一定程度上降低了城市分布对其他因素的依赖。 Adopting the data of all cities and organic county towns, the paper uses nearest neighbor analysis and population distribution theory to research inter-provincial differences and their impact factors of urban spatial distribution in China. The spatial units are the provincial level districts. The results show that ： in 2009, urban spatial distribution pattern is a uniform distribution in most provinces. Only Tibet, Qinghai and Xinjiang are in obvious cluster distributions. Through the regression analysis it is found that there is a strong correlation between spatial distribution patterns and natural, socio-economic factors. Viewed from coefficients of variables, the most important factor is road network density which affects the regional urban distribution patterns; the followed factors are multiple cropping index, per capita arable land, land reclamation rate and urbanization level. Through the development process of cities, each city must maximize the capture of resources in order to obtain sufficient elements to maintain its growth, which leads to competition for resources among cities. In a homogeneous external environment, the spatial distribution tends to he uniform. The heterogeneous external environment leads the cities to take the cluster distribution pattern. Multiple cropping index and urbanization level＇ s coefficients are negative, indicating when the multiple cropping index and urbanization level increase and other factors are unchanged, the urban distribution＇ s dependence on other factors is relative lowered.
