摘　　要：根据全国林业碳汇计量监测体系建设2012年云南省试点项目及云南省第四次森林资源规划设计调查采集的169个森林土壤剖面资料,采用土壤类型法,对云南省9个主要森林土壤类型的有机碳密度进行研究分析。结果表明:不同土壤类型的土壤有机碳密度差异较大,从高到低依次为黄棕壤、棕壤、黄壤、暗棕壤、石灰土、红壤、赤红壤、砖红壤、紫色土,除紫色土与暗棕壤发生倒退变化外,排序与有机质含量一致。从纵向上比较,高海拔地区的林下土壤有机碳密度较高;从橫向上比较,云南森林土壤有机碳密度除暗棕壤外,其余均高于全国水平。Based on the data of 169 forest soil profiles collected from pilot project of forestry carbon sequestration monitoring system in 2012 and the fourth forest resources inventory and planning in Yunnan,the organic carbon densities of 9 major forest soil types were studied and analyzed by soil type method.The results showed that the organic carbon densities of different soil types varied greatly,sorting from high to low by yellow brown soil,brown soil,yellow soil,dark brown soil,limestone soils,red soil,lateritic red earths,humid-thermo ferralitic and purplish soil,which was consistent with the sequence of organic matter content except the retrograde change of purplish soil and dark brown soil. In terms of vertical comparison,the soil organic carbon density was higher in high altitude area while in terms of horizontal comparison,the soil organic carbon density in Yunnan forest was over the national level except for the dark brown soil.
