摘要:

应用集中系数、区域非均衡系数、改进的重力模型对客货运量分别进行评价,并通过定性的方法对结果进行修正,得出结论:(1)新疆城市客货运的集中程度差异明显;(2)新疆客货运输的节点不一致,呈现出不同的变化趋势;(3)目前新疆基本形成以乌昌地区为中心,以"奎屯-乌苏"双核城市和喀什为次中心,以石河子、博乐、库尔勒、阿克苏、阜康为区域中心,其他城市为区域次中心的城市等级体系.

关键词: 客货运量, 重力模型, 集中系数, 非均衡系数, 城市等级体系, 新疆

Abstract:

This study used concentricity coefficients, disequilibrium coefficients, and ameliorative gravitation model approach to estimate the passenger and cargo fluxes in the recent years in Xinjiang. Then the results were fixed through qualitative analysis. The conclusions are as follows: (1)Disequilibrium coefficients are obviously different; (2)The node cities are also different, showing diverse trends; and (3)At the present, the city hierarchical system takes "Urumuqi-Changji" as center, "Kuytun-Usu" and Kashgar as subordinate centers, Shi Hezi, Bole, Korla, Aksu, and Fukang as regional centers, and the other cities as regional subordinate centers.

Key words: passenger and cargo fluxes, gravity model approach, concentricity coefficient, disequilibrium coefficient, city hierarchical system, Xinjiang
