摘　　要：城市的可持续发展离不开城镇用地的合理安排与布局优化.本文以2004—2014年内蒙古城镇土地利用数据为基础,对内蒙古自治区12个盟市城镇用地规模变化、分异特征及区域差异进行了定量化研究,并通过面板数据模型对城镇用地扩展的影响因素进行了估计.从规模变化上看,研究期间内蒙古城镇用地呈现出扩张的趋势,扩张幅度在不同时期具有明显的阶段性特点.从分异特征上看,内蒙古城镇用地总体综合变动指数为1.05,通过自然间断法划分剧变型、缓变型和稳定型3种变动类型,且中部区域的盟市变动相对剧烈并在空间上呈现出一定规模的集聚效应.从区域差异上看,内蒙古城镇用地扩展规模的总差异来源于区域内差异,而区域内差异主要是由东部盟市的差异所致.研究发现,受经济发展、城镇化水平和耕地资源禀赋等相关因素的驱动,内蒙古城镇用地扩展的区域差异较为显著,其中,东部和西部地区受人均耕地面积影响较大,而中部地区受人均GDP的影响较小.The aim of the present work was to quantitatively analyze the spatial patterns of changes in urban land use, including change type and amplitude change speed, and trend in Inner Mongolia over the past 10 years. The major findings are as follows. From 2004 to 2014 urban land use had changed in stages land use from 2004-2009 was more heated then from 2009-2014. Theil index was used to analyze regional differences. It was found that overall difference in urban land use primarily stemmed from regional differences, while regional differences were due to uneven land use in eastern cities of the region. Dynamic differentiation and graded rate analysis indicated that in small and medium-sized cities the overall transmission rate was higher than in larger cities. Transfer coefficient analysis revealed more prominent stages in change ratios Comprehensive change index analysis found the overall comprehensive change index to be 1.05. Natural discontinuous method was used to determine urban land use by dynamic differentiation of three types, the dramatic variant, slow variant and the stable variant Urban expansion due to economic development, urbanization and cultivated land resources endowment were found to be the driving forces Eastern and western regions were greatly influenced by cultivated land resources, and less affected by economic development in central Inner Mongolia.
