摘要: 基于能源消费视角，通过构建土地利用碳排放核算模型，从土地利用碳排放核算、碳足迹和碳排放强度3个方面，对重庆市1997－2010年的土地利用碳排放效应进行时空变化分析．结果表明：（1）重庆市土地利用碳排放总量呈增加趋势，由1997年的3796.12×104 t增加到2010年的9435.21×104 t ；独立工矿用地的地均碳排放强度最大；单位GDP碳排放强度呈现下降趋势，节能减排实施效果明显；碳足迹呈增加趋势，生产性土地面积不足以补偿土地碳足迹；（2）土地利用碳排放和碳足迹的多少顺序在空间上呈现出：“一圈”，“渝东北”，“渝东南”的空间分布状态．

Abstract: Based on the perspective of energy consumption ,carbon emission of land use model had been built in this the article and the space and time changes of carbon emission effects of land use analyzed from1997 to 2010 in Chongqing ,from the estimated carbon emission of land use ,carbon footprint and car-bon emission intensity .The conclusions can be drawn as follows :1) Total carbon emission of land use of Chongqing city has increased from 3 796 .12 × 104 t (1997) to 9 435 .21 × 104 t (2010);Carbon intensity per unit area of independent industrial land is the most types of land use ;Carbon intensity per unit of GDP are decreasing ,energy-saving and emission reduction have obvious effects ;Carbon footprint is increasing ;the area of productive land cannot adequately compensate carbon footprint .2) The spatial distribution of the carbon emission of land use and carbon footprint presented :“one hour economic circle”greater than“north east wing of Chongqing” greater than “south east wing of Chongqing”.
