摘　　要：基于城市流理论,依据城市流强度分析方法,对兰州-西宁-银川城市带各城市的区位熵、外向功能量、城市流强度及其结构进行了测算与分析。结果表明:兰州的城市流强度远高于其他城市,是该城市带的集聚辐射中心;城市总体经济实力与城市流倾向度的相对比例关系不够协调,除兰州外,均表现出城市流倾向度高于城市总体经济实力的特点;城市总体经济实力不足导致城市综合服务能力低是影响兰西银城市带城市流发展的真正原因。最后指出兰西银城市带目前存在城市流强度低、城市流强度结构不合理等问题,结合城市带发展现状,在此基础上提出强化兰西银城市带城市流的几点建议。Using the urban flow theory and analytical method of the intensity of urban flow we calculated and analyzed the Lanzhou-Xining-Yinchuan Urban Corridor of the territorial quotient for the main extrovert service,the extrovert energy,the intensity of urban flow and its structure.The results showed： Lanzhou,with high-degree urban flow intensity,is the center of this region;apart from Lanzhou,the overall economic strength is lower than the degree of tendency of urban flow,the overall economic strength and the degree of tendency of urban flow of relative proportions is uncoordinated;The real reason for affecting the urban flow of Lanzhou-Xining-Yinchuan Urban Corridor development is the collectivity strength shortage in the cities.The direction of intensifying urban flows of these six cities is that Lanzhou should improve the integrated service ability,Xining and Yinchuan should perfect the urban function,the other cities should adjust the industry structure,enhance the urban economic,and present the corresponding optimal strategies of enhanced urban flow for each city.
