摘　　要：探讨广西贫困地区建设用地扩展的时空特征,并分析其驱动因素,有利于促进城市节约集约用地和城乡统筹发展,为扶贫攻坚提供有力保障,助推脱贫攻坚,推动社会经济可持续发展。本文以广西28个贫困县为研究对象,选取2000、2005、2010及2015年四个时间节点的相关数据。通过计算扩展速度、强度、弹性指数以及空间自相关分析来探讨研究时段内建设用地扩展的时空特征。研究结果发现:(1)研究时段内,广西贫困地区建设用地呈增长趋势,但增长速度较为缓慢。(2)从各时段的建设用地扩展情况来看,2005—2010年扩展速度最快、扩展强度最大;2000—2005年扩展弹性最大,2010—2015时段内的弹性最小,建设用地利用呈粗放到集约的趋势发展;(3)广西贫困地区建设用地扩展的时空特征呈现明显的空间自相关性。该研究结果可为贫困地区建设用地利用机制、新型城镇化发展、扶贫攻坚提供科学参考依据。Exploring the spatial and temporal characteristics of construction land expansion in poor areas of Guangxi and analyzing its driving factors are conducive to promoting the economical and intensive use of land in cities and the coordinated development of urban and rural areas,providing a strong guarantee for poverty alleviation,boosting poverty alleviation and promoting sustainable social and economic development.This paper takes 28 poor counties in Guangxi as the research object,and selects the relevant data of four time nodes in 2000,2005,2010 and 2015.By calculating the expansion speed,intensity,elasticity index and spatial autocorrelation analysis,the spatio-temporal characteristics of construction land expansion during the research period are discussed.The results show that:(1)During the study period,the construction land in poor areas of Guangxi showed an increasing trend,but the growth rate was relatively slow.(2)According to the expansion of construction land in each period,the expansion speed and intensity from 2005 to 2010 are the fastest and the largest.The elasticity of expansion is the greatest in 2000-2005 and the smallest in 2010-2015.The utilization of construction land shows a trend from extensive to intensive.(3)The spatial and temporal characteristics of construction land expansion in poor areas of Guangxi show obvious spatial autocorrelation.The results of this study can provide scientific reference for the utilization mechanism of construction land in poverty-stricken areas,the development of new urbanization,and poverty alleviation.
