| 摘 要： | 以断裂点模型为基础，以城市场强模型为工具，引入中心城市综合实力和城市间时间成本加权距离两个指标对模型进行修正，结合水分分析方法，对长三角15个中心城市的影响腹地进行划分，比较城市腹地的面积大小及分布情况，并在腹地划分的基础上叠加市域行政范围来揭示长三角各城市腹地范围与行政范围的相互关系。研究结果可为长三角行政区划调整等提供参考。

| Abstract: | Based on the break-point principles and by improving the city potential model with the indexes of central city comprehensive competence and cost weighted distance,the results of hinterland division in 15 cities of the Yangtze River Delta are achieved by making use of hydrology analysis method to calculate the city break-points.By comparing their area with the municipal boundaries,Their relationships are identified as four types.The results of the research can be referenced to the adjustment of administrativ... |
