【摘要】：城市空间扩展除受城市自身的自然、社会、经济、文化、技术条件的影响外,还受城市所在区域经济发展水平和在大区域城镇体系中的角色定位等因素的影响,呈现出形成和发展的不同特点和规律。本文采用GIS技术分别对河西走廊敦煌市、金昌市、张掖市三种职能类型差异显著的城市中心城区2004年、2009年、2014年建设用地空间扩展情况进行分析,以年均扩展量、年均扩展速率来比较三个时间点和两个阶段城市空间扩展的强度变化,并采用"等扇分析法"对三个城市中心城区空间扩展的各向特征进行量化分析,研究各类城市空间扩展的用地结构特征,总结不同类型城市空间扩展模式。并在此基础上,从社会效益和协调性两方面评析了不同类型典型城市空间扩展绩效。
[Abstract]:The expansion of urban space is affected not only by the natural, social, economic, cultural and technological conditions of the city itself, but also by the level of economic development in the region where the city is located and its role in the system of large regional towns. It presents different characteristics and laws of formation and development. In this paper, the spatial expansion of construction land in Dunhuang City, Jinchang City and Zhangye City in Hexi Corridor in 2004, 2009 and 2014 were analyzed by using GIS technology. The average annual expansion rate is used to compare the intensity changes of urban spatial expansion between three time points and two stages, and the "equal fan analysis" is used to quantify the spatial expansion characteristics of the three urban centers. This paper studies the land structure characteristics of urban spatial expansion and summarizes different urban spatial expansion models. On the basis of this, the paper evaluates the performance of different types of typical urban space expansion from two aspects of social benefits and coordination.
