摘　　要：为了研究山西省不同土地利用类型对区域生态系统碳循环的影响,进而为山西省发展低碳经济提供参考和依据,构建了碳排放计算模型,对能源消费的碳排放量进行了测算;将不同土地利用类型与能源消费项目进行对应,构建了基于净生态系统生产力(NEP)的碳足迹模型,并对山西省不同土地利用方式的碳排放和碳足迹进行了分析。结果表明:2012~2019年山西省能源消费的碳排放总量呈上升趋势,其中人类活动集中的城镇村及工矿用地的碳排放量和碳排放强度均最大;虽然全省的碳汇总量呈增长的趋势,但是历年的碳足迹压力指数均大于1,区域碳循环系统压力过大;全省的碳足迹总量亦呈增长态势,且远大于实际生产性土地面积,生态赤字严重。因此,优化城镇村及工矿用地等高碳排放的土地利用方式,以及调整以煤炭为主的能源消费结构,是山西省降低区域碳排放和碳足迹的关键。In order to explore the impact of different land use types on the carbon cycle of regional ecosystem in Shanxi Province and provide reference and basis for the development of low-carbon economy,the carbon emission model was constructed.The carbon emissions of energy consumption are calculated,and different land use types are corresponding to energy consumption projects.The carbon footprint model is constructed based on net ecosystem productivity(NEP),and the carbon emissions and carbon footprints of different land use patterns in Shanxi Province were analyzed.The results show that the total carbon emissions of energy consumption in Shanxi Province show an upward trend from 2012 to 2019,in which the urban and village and industrial and mining land with concentrated human activities have the highest carbon emissions and carbon emission intensity.Although the total carbon sequestration of the whole province shows an increasing trend,the carbon footprint pressure index over the years is greater than 1.The pressure of the regional carbon cycle system is excessive.The total carbon footprint is also increasing,which is much larger than the actual productive land area,and the ecological deficit is serious.It can be seen that the optimization of high-carbon emission land use patterns such as urban,village and industrial and mining land and the adjustment of coal-based energy consumption structure are the key to reduce regional carbon emissions and carbon footprint in Shanxi Province.
