摘　　要：以县(旗、区)为研究单元,从人口城市化、经济城市化、社会城市化和空间城市化四个方面采集20个指标构建了城市化综合评价指标体系,利用2001年、2005年和2009年三个年份的数据,用主成分分析、空间自相关分析和GIS可视化表达的方法研究了呼包鄂榆经济区内城市化水平的时间变化和空间分异。结果表明:第一,呼包鄂榆经济区城市化水平的时间变化特点是县域城市化水平区域差异年际变化整体基本稳定,局部有明显变化,城市化水平形成明显的等级差异;第二,呼包鄂榆经济区城市化水平的空间变化特点是区域城市化水平整体偏低,综合分值低于0的县(旗、区)占到六成以上;第三,呼包鄂市辖城区形成三个城市化中心,区内城市化水平具有低值集中、高值分散的特点;第四,包头市和呼和浩特市是城市化的热点区域,榆林市是城市化的盲点区域,榆阳区是城市化的隆起区域,白云鄂博区和石拐区是城市化的凹陷区域。To study the temporal and spatial variation of the urbanization level within Hohhot - Baotou - Erdos - Yulin Economic Zone, this essay takes the county as unit to set up the comprehensive evaluation index system of urbanization about twenty indicators from four kinds of population, economic, social and spatial urbanization by collecting the data of 2001, 2005 and 2009 and using principal component analysis, spatial autocorrelation analysis and GIS visualization methods. The results show that： Firstly, the temporal changes characteristics of the level of urbanization in the Hohhot - Baotou - Erdos - Yulin economic zone is overall basically stable, but local significant variability about county regional differences in the level of urbanization. There is a significant difference of the level of urbanization in the Hohhot- Baotou- Erdos- Yulin economic zone. The level of urbanization of municipality＇ s urban district is relatively higher in the Hohhot - Baotou - Erdos, and the level of other counties （banners, district） is relatively low. Secondly, the spatial changes characteristics of the level of urbanization in the Hohhot - Baotou - Erdos - Yulin economic zone is regional urbanization levels are generally low, and the overall score lower than 0 of counties （banners, district） accounted for more than 60%. Thirdly, the municipality＇ s urban district in the Hohhot - Baotou - Erdos has formed the three centers of regional urbanization levels. The regional urbanization levels have the characteristics of the low value of concentration and the high value of dispersed. Fourthly, Baotou City and Hohhot City is the urbanization of hot spot area; Yulin City is the urbanization of blind spot area; Yuyang District is the urbanization of bulge area; Baiyunebo District and Shiguai District are the urbanization of recessed area.
