摘    要:研究城市功能用地演替可以揭示出新时期中国城市功能空间演化的特征、趋势与形成机制,为城市管理提供理论依据。本文以张掖中心城区为研究范围,运用GIS工具及方法,定量分析了张掖市1981年以来居住用地、工业用地、公共服务用地三大功能用地的空间演变特征及其动因,进而绿洲城市空间的可持续发展提供指导。研究发现:张掖城市居住用地和公共服务用地呈逐步增加趋势,空间上呈“内聚→外散”的演变趋势,两者均由老城区向四周扩散,而工业用地先增加后减少,空间上呈“混杂→集中”的转变特征,整体上集中于东北部产业园区内。张掖城市功能用地演变是人口经济驱动、宏观政策调控、城市开发与生态环境博弈、交通线路牵引、城市规划引导等共同作用的结果。

关 键 词:城市功能用地  城市空间结构  演变  张掖主城区

Abstract:China is in a critical period of rapid urbanization and urban spatial reconstruction. Under the constraint of water and soil resources, the urbanization process and the urban spatial structure of the oasis cities that are located in Northwest China are different from the cities of other regions. The study of its spatial structure is of significance in urban space reconstruction. Urban functional land is the material carrier of urban space. The research on the evolution of urban functional land can not only reveal the characteristics, trends and formation mechanisms of urban functional spatial evolution, but also provide guidance for urban space management. This paper extracts the main functional land patches based on the map of the three phases urban construction in the downtown of Zhangye City which is a typical oasis city in the Hexi Corridors, Gansu Province, China and uses the nuclear density estimation analysis and the circle analysis to analyze the spatial evolution characteristics and the motivation of residential land, industrial land and public service land since 1981 in Zhangye City. The results showed as follows: (1) Since 1981, the proportion of residential land and public service land based on living have been increased year by year in urban construction land, while the proportion of industrial land based on production has been gradually declined. (2) Residential land and public service land is gradually spread from the old urban area to the periphery of the city, and these two types of functional land gradually are diffused from downtown space to the periphery. However, industrial land is gradually concentrated in the industrial park, driving the rapid growth of urban space in Zhangye. (3) The urban functional land also has obvious circle characteristics. (4) The evolution of urban functional land is the result of the combined effects of the driving forces by the population and economy, the regulation and control by the policy, the trade-off between urban development and eco-environment protection, constraint by the traffic transportation and the guidance by the urban planning.
Keywords:urban functional land  urban spatial structure  evolution  downtown of Zhangye City
