| 摘 要： | 推进丝绸之路经济带建设是中国西北地区开发开放、转型发展的重大机遇,明确各省、市空间发展定位,避免同质化竞争是国家战略稳步实施的关键。以丝绸之路经济带甘肃段各节点城市为研究样本,通过主成分分析测算样本城市综合质量,在明确核心节点城市的基础上修正研究模型计算得出的各节点城市间的引力值和作用场强。结果显示:丝绸之路经济带甘肃段各节点城市在发展过程中组团化与空间分异化特征并存,兰州是丝绸之路经济带甘肃段的核心城市,同周边城市联系紧密、融合互动发展能力强。嘉峪关城市发展存在偏心化,发展重心向酒泉转移。酒泉城市综合质量较高,具备带动周边城市发展的能力。张掖经济发展模式单一,区域协同发展基础薄弱,亟需提高城市引力,与武威、金昌等城市实现联动。庆阳、平凉具备实现孤岛城市和孤点城市向龙头和龙尾城市转变的基础。陇南城市综合质量低,城市引力与场强不足,需要联系周边城市协同发展。临夏、甘南作为少数民族地区,需提升城市发展水平,摆脱孤点城市困局。最后,针对研究结果就丝绸之路经济带甘肃段节点城市空间差异进行梳理,并就各自发展策略提出相关建议。

| Abstract: | Construction of the Silk Road Economic Belt is the significant opportunity for opening up and conversion development in northwest China.It is the key for implementing the national strategy to clear the space development localization and avoid the homogeneous competition in various provinces.The comprehensive quality of the node cities along the Silk Road Economic Belt in Gansu Province was measured by PCA,and the values of gravity and field strength of the cities were calculated.Result showed that both the spatial group and differentiation coexist in development of the node cities,Lanzhou should be positioned as the core node of the Silk Road Economic Belt in Gansu Province,and it contacts closely with the surrounding cities and has the interaction development capability.There is an eccentric character in urban development of Jiayuguan,and Jiuquan has a capability to drive the development of surrounding cities.The economic development mode of Zhangye is simple,the urban gravity needs to be improved so as to realize the economic linkage development with surrounding cities.Qingyang and Pingliang have the basis of urban conversion from the lack of contact to the close linkage.The comprehensive quality of Longnan is weak,the urban gravity and the field strength are insufficient,and the synergetic development with surrounding cities needs to be achieved.Linxia and Gannan should enhance the level of urban development and get rid of the urban dilemma. |
