【摘要】：针对云南省城市发展水平落后且存在不均衡问题,修正了威尔逊模型和重力模型中的相关参数,用交通距离代替空间欧氏距离,利用数据拟合方法求算距离衰减系数,分别测算了云南各州市的对外扩散强度和扩散范围,并利用皮尔森相关分析法分析了影响云南省农业发展的主要因素。研究结果表明,两种模型交叉检验的结论一致,实验具有合理性和可信性;云南城市发展呈明显的中心极化效应,昆明的城市空间扩散能力远远大于其他州市;除了距离和各州市的自身实力外,交通可达性也会对扩散能力产生影响;少数民族聚集地延续原始的农耕方式是阻碍云南现代化发展的最直接因素,同时,耕地土壤质量低也会制约农业生产。
[Abstract]:In view of the backward and unbalanced urban development in Yunnan Province, the parameters of Wilson model and gravity model are modified, and the distance attenuation coefficient is calculated by using the data fitting method instead of the Euclidean distance. The external diffusion intensity and diffusion range of Yunnan were calculated, and the main factors affecting the development of agriculture in Yunnan were analyzed by Pearson correlation analysis method. The results show that the results of cross-test of the two models are consistent, the experiment is reasonable and credible, the urban development of Yunnan has obvious central polarization effect, and the spatial diffusion ability of Kunming is much larger than that of other cities. Apart from distance and the strength of the cities themselves, the accessibility of transportation will also have an impact on the diffusion capacity. The continuation of primitive farming methods in ethnic minority areas is the most direct factor hindering the development of modernization in Yunnan, and at the same time, The low quality of cultivated soil will also restrict agricultural production.
