西部大开发战略下的成渝经济区研究——基于城市流强度模型

城市流强度是表征城市对外服务功能的量化指标,它描述了城市对外联系的强弱。在西部大开发战略不断深入的宏观背景下,以即将上升为国家战略区域规划的成渝经济区为例,运用城市流强度的方法对区域内主要城市间的空间相互作用、城市流强度及其结构进行系统分析。成渝经济区内各城市的联系地位表现为：高城市流强度值城市为重庆和成都,是区域经济集聚和扩散的中心;中城市流强度值城市为德阳、绵阳、资阳、自贡、南充、达州、广安等7个城市,是区域次级辐射中心;低城市流强度值城市为眉山、遂宁、乐山、雅安、泸州、内江、宜宾等7个城市,为地方集聚和辐射中心。最后提出加强区域内城市联系的简要建议,以期加快成渝经济区的发展与壮大。

Research on Cheng-Yu Economic Zone under the Western Development Strategy: Based on the Urban Flow Intensity Model

The urban flow intensity describes the contacts among cities,and it is a quantitative index on the function of urban service.Under the background of Western Development strategy,taking the Cheng-Yu Economic Zone which will soon become the focus of national regional planning strategy as an example,the paper analyzes the main interurban space affects,the urban flows intensity and the structure mutually applying the methods of urban flow intensity.In the Cheng-Yu economic zone,cities relation status shown as: ...
