利用安徽省多目标区域地球化学调查(怀远灵璧地区)数据,计算怀远灵璧地区土壤全碳、有机碳、无机碳储量,按照不同的土壤类型、成土母质以及土地利用方式等,分析研究区表层土壤全碳、无机碳、有机碳储量及其分布分配特征.结果表明,表层土壤平均全碳储量为3866.13 t·km-2,有机碳平均碳储量为2528.22 t·km-2,无机碳平均碳储量为1337.91 t·km-2.与第二次土壤普查结果对比发现,区内土壤有机碳储量增加了0.77 Mt,累计速率2.9%.从平均碳储量分布特征看,全碳、无机碳在河流冲积物母质、潮土中储量最高,有机碳在酸性盐类风化物母质、水稻土、林地中储量最高.

Use of the data obtained by multi-purpose regional soil geochemical survey,the soil total carbon,organic carbon and inorganic carbon storage were calculated.And distribution characteristics of the above-mentioned carbon storages were analyzed in terms of soil type, land use classification and parent types.The results show that the soil total carbon,organic carbon and inorganic carbon storage are 3 866.12 t·km-2 ,2 528.22 t·km-2 and 1 337.91 t·km-2 ,respectively.The topsoil organic carbon storage of the Huaiyuan-Lingbi area has increased 0.77 Mt in recent 30 years.In terms of average carbon storage distribution,total carbon and inorganic carbon storage are the highest in river alluvial material and moisture soil while organic carbon storage of acidic rock parent material is the highest in paddy soil and forest land.
