内蒙古多伦县土地利用碳排放及其影响因素分析

Analysis on land use carbon emissions and influencing factors in Duolun county,Inner Mongolia

以内蒙古多伦县为研究区,结合1985-2015年间统计数据和土地利用变更数据,借助土地利用碳排放计算模型和STIRPAT模型,分析区域土地利用碳排放动态变化及其主要影响因素。结果表明:土地利用碳排放的年均增加值为0. 684×10~4t,呈逐年增加趋势,其中建设用地的碳排放量起主导作用;单位GDP的碳排放强度呈逐年减少趋势;人均碳排放强度则呈逐年增加趋势。对土地利用碳排放影响最大的因素是GDP,其次是第一产业,其三是第三产业,最小的是人口数量。

Taking Duolun county,Inner Mongolia as the research area,statistical data and land use change data in 1985 to 2015 were used and by carbon emission calculation model and STIRPAT model,the dynamic changes of land use carbon emissions and their main influencing factors in area were analyzed.The results showed:the average annual carbon emissions from land use was 0.684×104 t,showing an increasing trend.Among them,carbon emissions from construction land played a leading role.Carbon emission intensity of GDP per unit showed a decreasing trend year by year;per capita carbon emission intensity increased year by year.The most important factor affecting land use carbon emissions was GDP,followed by the primary industry,the third is the tertiary industry,and the last is the population.
