引力模型重构在城区与郊区相互作用中的应用——以昆明市为例

在以往的研究中，引力模型仅考虑影响空间相互作用的少数因子，具有变量的数据较容易获取．且算法较为简单的优点。但考虑因子太少，使引力模型所测算的空间相互作用力与现实产生偏差，显得有些粗糙。因此，本文考虑多项指标对引力模型中区域“质量”评价的重要性，并对引力模型中“距离”的内涵进行了深化．构建了新的模型。在重构模型的基础上。文章选择昆明市城区与郊区作为研究对象进行实证研究．旨在分析城区与郊区空间相互作用的程度．并为促进城区与郊区一体化发展提出建议。

Application of Reconstruction of Gravitation Model in the Space Reciprocity between the City Zone and the Suburb

In the past, Gravitation Model takes accout of only a few factors, which had the advantage of easily getting date and calculating, but there were some flaws in this method. Therefore, the paper takes account of the importance of many indexes in the evaluation of the areas＇ quality, and deepens the conception of the distance, which reestablishes the new Gravitation Model. On the base of the reestablishing model, the paper selects the City Zone and the Suburb of Kunming city as a researching target, in order to analyze the degree of the space reciprocity between the City Zone and the Suburb, and some suggestions for two areas＇ communication have been put forward..
