陕西省土地利用碳排放演变与影响因素分析研究

以陕西省统计数据为基础,利用土地利用碳排放模型和STIRPAT模型,分析了陕西省1999年-2013年土地利用碳排放演变与影响因素,结果表明:陕西省碳排放量呈增加趋势,增加了4.07倍,其中建设用地碳排量增加起主导作用.碳排放经历了减少(1999-2000年)、稳步增加(2001-2006年)和快速增加(2007-2013年)3个阶段.人口数量和GDP是陕西省土地利用碳排放变化的影响因素,其中人口数量对碳排放变化的贡献高于GDP.经济集约式发展和个人集约式低碳消费是碳减排的重要方向.

Analysis of Influential Factors and Evolution of Land Use Carbon Emissionin Shanxi Province

Land use carbon emission model and STIRPAT model were used to analyze evolution of land use carbon emission and its influencing factors on the basis of Shaanxi Provincial Statistical Yearbook data. The result showed:Carbon emission showed an in-creasing trends in Shaanxi province from 1999 to 2013, and the amount of carbon emission increased 4. 07 times. In the process of carbon emission increasing, carbon emission of construction land was paly a leading role. The process of carbon emission in Shaanxi province was divided into 3 stages with carbon emissions reduction stage ( 1999-2000 ) , steadily increasing stage ( 2001-2006 ) , and rapid increasing stage(2007-2013). Population and GDP were the influencing factors of carbon emission induced by land use in Shaanxi province, and the contribution of population on carbon emission was higher than GDP. Intensive economic development and intensive personal carbon consumption would be the main task of carbon emissions reductions in Shaanxi province.
