【摘要】：以1989~2013年中国统计数据为基础,借助土地利用碳排放计算方法和STIRPAT模型,分析土地利用碳排放演变与影响因素,结果表明:1土地利用碳排放量呈增加趋势,其中建设用地碳排放量起主导作用。研究时段土地利用碳汇略有增加,但远不能抵消建设用地碳源作用。2土地利用碳排放过程划分为四个阶段,即1989~1996年碳排放量稳定增加、1997~2001年碳排放量缓慢增加、2002~2007年碳排放量急剧增加、2008~2013年碳排放量快速增加阶段。3研究时段内单位GDP碳排放强度减小,人均碳排放强度增加。4土地利用碳排放与人口数量呈负相关关系,与GDP呈正相关关系。
[Abstract]:Based on the statistical data of China from 1989 to 2013, with the aid of land use carbon emission calculation method and STIRPAT model, the evolution and influencing factors of land use carbon emissions were analyzed. Among them, carbon emissions from construction land play a leading role. The land use carbon sink increased slightly during the study period, but it could not counteract the carbon source effect of construction land. 2. The process of land use carbon emission was divided into four stages. That is to say, the steady increase of carbon emissions from 1989 to 1996 and the slow increase of carbon emissions from 1997-2001 to 2002- 2007 have led to a sharp increase in carbon emissions during the period of rapid increase of carbon emissions from 2008 to 2013. The intensity of carbon emissions per unit GDP has been reduced during the period of 3. 3 of the study period. The increase of per capita carbon emission intensity has a negative correlation with the number of population and a positive correlation with GDP.
