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。
The scientific study of urban location provided theoretical support and practical basis for urban planning and urban location.This paper attempted to introduce resource and environment as the important location factors into the traditional study of location,and emphatically analyzed transportation,public facilities,land and water resources and ecological environment of five cities in the Hexi Corridor by means of index of status,location entropy and evolution of comprehensive transportation accessibility. The results showed that the rank of regional space support capacity of five cities in the Hexi Corridor. The orders of the advantage urban were: Zhangye City,Jiayuguan City,Jiuquan City,Wuwei City,Jinchang City. Zhangye City was the best area. Indices of status of resources and environment constraint indicators for five cities in the Hexi Corridor were in crisis and early warning state,Zhangye City was relatively optimal. The traffic between the cities was different,the transportion of Jiayuguan City was the best. The index of transportation accessibility of Jiayuguan City was 1. 8 times bigger than Jinchang City. The development of public facilities was not balanced,there were some advantageous industries in Zhangye City and Jiuquan City.According to the analysis results of location factors,this paper put forward some reasonable suggestions for those cities,but also provided references for healthy development of urban and regional cooperation under the new situation.
