摘　　要：本文基于马武至龙潭一级公路工程临时用地土地复垦,采用碳效应计算模型,对不同临时用地土地复垦的土地利用结构碳效应、工程实施碳效应及复垦管护碳效应进行分析。结果表明:(1)不同临时用地土地利用结构碳效应的固碳量表现为:弃渣场(513.20 t)>拌和站(11.82 t)>施工便道(11.73 t),管护碳效应的碳排量大小为:弃渣场(238.48 t)>拌和站(6.80 t)>施工便道(6.50 t);(2)临时用地工程实施碳效应的碳排放量依次为:弃渣场(913.57t)>施工便道(12.88 t)>拌和站(5.97 t);(3)弃渣场的土地复垦碳排放量明显高于其他类型临时用地,碳排放量分别为拌和站、施工便道的672.5倍、83.5倍。建筑材料的消耗是弃渣场土地复垦碳排放的主要来源,能源消耗是拌和站和施工便道土地复垦碳排放的主要来源。Based on the temporary land reclamation of Mawu Longtan first-class highway engineering,this study used the carbon effect calculation model to analyze the carbon effect of land use structure,project implementation and reclamation management and protection of different temporary land reclamation.The results show that:(1)the carbon sequestration capacity of different temporary land use structures in the order:abandoned dreg site(513.20 t)>mixing station(11.82 t)>construction road(11.73 t).The carbon emission in management and protection was as follows:abandoned dreg site(238.48 t)>mixing station(6.80 t)>construction road(6.50 t).(2)The carbon emission of different temporary land project implementation was abandoned dreg site(913.57 t)>construction road(12.88 t)>mixing station(5.97 t).(3)The carbon emission of abandoned dreg site was significantly higher than other types of temporary land,being 672.5 times and 83.5 times higher than those of mixing station and construction road,respectively.The main carbon emission source of abandoned dreg site land reclamation is consumption of building materials,while the main carbon emission source of mixing station and construction road is energy consumption.
