摘　　要： 采用全国县级以上城市数据,运用最近邻与空间自相关分析,定量分析了1985—2010年中国城市体系的空间分布格局的时空特征与演变规律。结果表明:在1985—2010年间,中国城市的整体分布主要呈集聚型,其集聚程度有着逐渐增强的趋势。不同规模的城市在空间上的分布类型存在很大差异。集聚强度随着城市规模的变大而降低,表明随着城市规模的扩大,互斥作用不断加强。超大型、特大型城市由均匀分布转变为随机分布说明随着经济的发展,城市化总体水平的提高,城市发展对自然条件的依赖相对降低。从局部区域上城市的空间集聚或空间关联性质来看,其集聚特征的反差十分鲜明。东部地带不同规模等级城市都较为发达,形成了高水平均衡模式。没有通过显著性检验的城市主要集中分布在中部地区。西部地区城市分布表现出较为强烈的空间极化特征。 Based on urban data of China, using nearest neighbor analysis and spatial autocorrelation analysis, the paper makes a quantitative analysis on the spatial distribution and evolution of urban system in China from 1985 to 2010. The results showed that： the overall urban spatial distribution of China was cluster pattern and the overall agglomeration degree has a trend to increase from 1985 to 2010. There is a significant difference in the spatial distribution patterns of different urban scale. The urban evolution has a strong ecological characteristic. With the expansion of the urban scale, the reasons for aggregation intensity＇ s decreases is exclusive role. Megapolis and hyper metropolis were transited from the uniform distribution to the random distribution indicating that with the economic development and urbanization level＇ s improvement, urban development＇ s dependence on the natural and socio-economic conditions is relative reduction. The clustering feature＇ s contrast is very clear. Different urban scale are more developed in the eastern zone, forming a high-level equilibrium pattern. The cities which can＇ t pass the sig- nificance test mainly concentrated in the middle zone, it means that the harmonious development ability has little improved in the region. Urban space distribution of the western zone show more strongly polarized characteristics, the imbalance of urban development within the zone has a further expansion trend.
