兰白西城市经济辐射区与空间发展趋势研究

The Research on Urban Economic Region and Spatial Developing Trends in LanBaiXi Region

通过对传统城市引力模型的修正和场强的引入,从定量角度,以兰州市为中心计算出城市间的相互作用力,确定兰州有效吸引区作为兰白西城市的经济辐射区,并根据其强、弱影响区的范围来预测兰白西城市经济辐射区的空间发展趋势。

From a quantitative point of view, using the dominant city of Lanzhou as the center area in order that calculates the interaction force between cities, Lanzhou is considered as the economic area of LanBaiXi through amendment of the urban traditional gravity model and introduction of the field. According to its strong and weak influence zone, it predicts the scope of urban agglomeration in the LanBaiXi spatial developing trends.
