摘　　要：城市流强度是量化城市外向服务功能的指标,反映了城市间空间联系的强弱。基于城市流强度模式,本文对2012年甘肃省12个地级市的外向功能量、城市流倾向度、城市流强度及其结构进行测度分析。分析结果表明:兰州属于高城市流强度值城市,经济实力突出、经济辐射能力强,是全省经济发展中心;白银、天水、庆阳与酒泉、嘉峪关、武威分别是甘肃东中部地区与西部地区的重要区域副中心,在各自所在地区发挥着带动功能;平凉、定西、陇南以及金昌、张掖等城市的城市流强度值较低,其辐射面主要是城市所在地,属于地方性经济中心。最后,提出增强甘肃省各城市空间联系的政策建议。Urban flow is the index,which calculates urban outward service function and reflects spatial collection among cities.Based on the model of urban flow, the paper analyzes the outward energy,the degree of tendency, the intensity of urban flow and the structure of intensity of urban flow,using Gansu＇s 12 city data in 2012. The results show as follows： Lanzhou has high intensity of urban flow, its economy is developed, stimulated whole area, and become the center of whole province;Baiyin, Tianshui and Qingyang and Jiuquan, Jiayuguan, Wuwei are important secondary regional centre in Gansu＇s mid-eastern and western area,respectively stimulating regional economic development;Pingliang,Dingxi,Longnan and Jinchang,zhangye have low intensity of urban flow,are local economic centers,stimulating local economic development. Finally,some measures on building up Gansu＇s urban special relation are put forward.
