摘　　要：以皖江城市带为例,采用空间自相关模型对其城镇化空间相关格局进行分析,进而分析跨江城市群城镇化发展的机制。结果表明:(1)2010年以来,皖江城市带城镇化水平呈上升趋势但不稳定,区内差异性减弱且质量有所提高,城镇化水平与经济发展水平不一致;(2)从全局空间关联角度来看,皖江城市带城镇化水平在空间上存在明显的正相关性即存在空间集聚现象;(3)从局部自相关角度来看,H-H集聚区即热点区存在沿长江东移的趋势,H-L集聚区主要位于宣城,L-H集聚区向铜陵演变,L-L集聚区位于皖江城市带西部六安、安庆、池州,且发展稳定;(4)江河功能的嬗变、政府政策的鼎革、城市之间竞速发展与地理扩散是跨江城市群城镇化发展的特有机制。The paper constructs valuation index system of urbanization by usingAHP methods,to measure and evaluate the level of urbanization in WanjiangCity Belt.And uses spatial correlation model to analyze spatial pattern ofurbanization and then make suggestions,analyze urbanization mechanism of River-crossing cities.The result shows that since2010,urbanization level inWanjiang City Belt is rising,but the trend is unstable.The differences amongWanjiang City Belt is weakening and quality is improving,and the level of urbanizationis not the same as the level of economic development.From theglobal spatial correlation point of view,Wanjiang City Belt’s urbanizationlevel are concentrated.From the local spatial correlation point of view,H-Hcorrelation pattern has the trend of moving along the Changjiang River to theeast,H-L correlation pattern is primarily in Xuancheng,L-H correlation patternevolves to Tongling,L-H correlation pattern locates in Luan,Anqing,Chizhou,and the development is stable.Change of river’s function,update ofgovernment’s policy,competition of cities are mechanisms of river-crossingcities,urbanization.
