摘　　要：通过分析2002～2011年间陕西省建设用地和碳排放的变化,基于LMDI模型分解方法,探讨了10年间建设用地变化对碳排放增长的影响.结果表明：研究时序内,陕西省建设用地和碳排放量均呈增长态势,建设用地年扩展率1.25％,碳排放年均增长8.84％,建设用地变化与碳排放量正向效应显著,建设用地对碳排放的贡献度为12.36％,对建设用地采取总量控制原则,能有效控制碳排放量,对陕西省实现“十二五”期间碳减排目标具有重大意义.This paper analyzed the change of construction land and carbon emissions from 2002 to 2011 in Shaanxi,discussed the effect of construction land change on carbon emissions growth in ten years.Results showed that the construction land and carbon emissions in Shaanxi were in growth,and the average annual expansion rate of construction land was 1.26%,carbon emissions increased 8.84% annually,construction land change and carbon emissions showed significantly positive effect.Carbon emissions contribution from construction land was 12.36%.Control the construction land by total amount can effectively control carbon emissions,which have great significance for achieving the target of carbon emisssion reduction during the ＂twelfth five-year＂in Shaanxi province.
