【摘要】：水土资源、生态环境、交通、公共设施是城市发展的重要支撑要素,影响城市区位的优劣。将资源与环境作为关键因子引入到干旱区城市区位研究中,采用"状态指数"法、综合交通可达性赋值测度法和区位熵分析河西走廊城市区位状况。结果表明:河西五市水土资源和生态环境区位多项指标处于危机和预警状态,张掖市相对最优;城市间交通区位差别较大且对内、对外交通基础设施不协调,嘉峪关市交通区位最好,交通可达性指数是金昌市的1.8倍;公共设施发展不均衡,具有区位比较优势的产业部门主要集中在张掖市和酒泉市。根据区位因子优劣的分析结果,为河西走廊城市发展提出建议。
[Abstract]:Soil and water resources, ecological environment, transportation and public facilities are important supporting factors of urban development, which affect the quality of urban location. This paper introduces resources and environment as key factors into the study of urban location in arid areas. The "state index" method was used. Comprehensive traffic accessibility evaluation method and location entropy analysis of urban location in the Hexi Corridor. The results show that the location of soil and water resources and ecological environment in the five cities of Hexi is in crisis and early warning state. The relative optimum of Zhangye city; The traffic location of Jiayuguan is the best and the traffic accessibility index is 1.8 times that of Jinchang. The development of public facilities is not balanced and the industrial departments with comparative advantage are mainly concentrated in Zhangye and Jiuquan. According to the analysis results of location factors, some suggestions are put forward for the urban development of Hexi Corridor.

【正文快照】： 区位论是研究人类活动最优空间的理论[1],城市区位研究以克里斯泰勒的“中心地理论”为开端,自20世纪30年代以来国内外学者不断修正拓展,在城市形成与发展动力、城市空间结构、城市体系等方面进行了深入的探索,城市区位研究已从最初单一职能的空间均衡条件下的中心地模型扩展
