【摘要】：以1989~2013年中國統(tǒng)計數(shù)據(jù)為基礎,借助土地利用碳排放計算方法和STIRPAT模型,分析土地利用碳排放演變與影響因素,結果表明:1土地利用碳排放量呈增加趨勢,其中建設用地碳排放量起主導作用。研究時段土地利用碳匯略有增加,但遠不能抵消建設用地碳源作用。2土地利用碳排放過程劃分為四個階段,即1989~1996年碳排放量穩(wěn)定增加、1997~2001年碳排放量緩慢增加、2002~2007年碳排放量急劇增加、2008~2013年碳排放量快速增加階段。3研究時段內單位GDP碳排放強度減小,人均碳排放強度增加。4土地利用碳排放與人口數(shù)量呈負相關關系,與GDP呈正相關關系。
[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.
