关中-天水经济区各中心城市城市流强度测算与分析

《关中-天水经济区发展规划》的获批,标志着＂大关中＂的发展进入了新的战略推进阶段。选择城市主要外向服务部门从业人员数为指标,根据城市流强度计算公式,对关中-天水经济区城市群各中心城市城市流强度进行了测算与分析。结果表明：高城市流强度值中心城市西安是经济区集聚辐射中心;中城市流强度值中心城市天水、咸阳,是区域次级集聚辐射中心,为次级区域中心城市;低城市流强度值中心城市铜川、商洛、渭南、宝鸡、杨凌,是地方集聚和辐射中心。进而提出强化城市流的区域发展政策：建立合理的城市规模等级结构,增强城市间经济空间联系;明确城市功能与产业定位,强化城市间分工与协作;建立跨区域合作组织,促进区域协同发展。

Measurement and Analysis on Urban Flow Intensity in Central Cities of Guanzhong-Tianshui Economic Zone

The approval of Development Planning of Guanzhong-Tianshui Economic Zone indicates that the development of ＂Great Guanzhong＂ has entered a new strategic promotion period.This paper selects indicators of employees in the main export-oriented service departments in cities to measure and analyze urban flow intensity of central cities in urban agglomeration of Guanzhong-Tianshui economic zone according to formula of urban flow inensity.The result shows that Xi＇an,the central city with high urban flow intensity,is the agglomeration and radiation center of the economic zone;Tianshui and Xianyang with medium urban flow intensity are the agglomeration and radiation sub-centers of the zone and are central cities in sub-zones;central cities such as Tongchuan,Shangluo,Weinan,Baoji and Yangling with low urban flow intensity are the local agglomeration and radiation centers.Based on the above analysis,this paper puts forward some regional development policies for intensifying urban flow so as to provide scientific references for quickening the planning and development of the urban agglomeration of Guanzhong-Tianshui economic zone.
