摘要
在浙江淳安一带开展1∶25万多目标地球化学调查,运用成熟的土壤碳储量计算方法,合理评估了该区的有机碳储量和无机碳储量分布特征,并估算了不同深度土壤碳储量。结果表明该区碳储量分布与土壤成土母质类型关系密切,不同土壤类型中有机碳、无机碳分布区域基本一致,高值区均位于黄壤和石灰岩土土区,低值区为红壤、粗骨土和湖底泥区。土壤有机碳储量在表层、中层、深层中表现一致,随深度的增加而增加,土壤无机碳储量在表层、深层较低,中层含量丰富。土壤有机碳储量较无机碳储量受自然因素和人为因素的综合影响较大。通过土壤碳储量的综合研究对当地特色产业经济具有指导意见。
This project carried out more than 1∶25 million target geochemical survey in Chun’an area of Zhejiang Province,using mature soil carbon storage calculation method,reasonably evaluated the distribution characteristics of organic and inorganic carbon reserves in this area,and estimated the soil carbon reserves at different depths.The results show that the distribution of carbon reserves in this area is closely related to the soil parent material type,and the distribution areas of organic carbon and inorganic carbon in different soil types are basically the same.The high value areas are located in yellow soil and limestone soil areas,and the low value areas are red soil,coarse bone soil and lake bottom mud areas.Soil organic carbon reserves are consistent in the surface,middle and deep layers,and increase with the increase of depth.Soil inorganic carbon reserves are low in the surface and deep layers,and the middle layer content is abundant.Soil organic carbon reserves are more affected by natural and human factors than inorganic carbon reserves.Through the comprehensive study of soil carbon storage,it has guidance for local characteristic industry economy.
