欠发达地区城市流强度及中心度研究——以甘肃省为例

Research of Urban Flow Intensity and the Degree in Less Developed Areas——A Case Study of Gansu Province

论文以甘肃省为例,利用城市流强度模型和中心度模型等方法分析欠发达地区省内城市间经济联系强度。结果表明城市经济实力与城市流倾向度不平衡,各城市经济地位相差很大;多数城市核心度佰较小,处于边缘区的分布范围;城市联系网络及处在相对单一、低层次的状态。因此,在未来的发展中应当更多地培育核心或者次一级核心城市,多带动欠发达地区经济发展,形成多中心经济网络。

Taking Gansu province as an example, use of the intensity of urban flow model and the center model, the paper analyzed intensity of economic links of cities in less developed areas. The results showed： The city＇s economic strength and urban flow tendency were imbalance, the economic status of each city varied greatly. Most of the urban core values were small in the distribution of marginal zone. Urban networks were in a relatively single, low level condition. Therefore, in the development of the future, the less developed areas should cultivate the more core and secondary core city, multipoint drive the economic development of Gansu province, multi-center network can be formationed eventually.
