摘　　要：基于温州市山地丘陵区开展的多目标地球化学调查获得的深、表层土壤有机碳和全碳数据,采用直线模型法计算了研究区表层(0~0.2 m)、中层(0~1.0 m)和深层(0~2 m)土壤无机碳的单位储量及密度;采用指数模型法计算了研究区表层(0~0.2 m)、中层(0~1.0 m)和深层(0~2 m)土壤有机碳的单位储量及密度。利用这些数据分别编制了表层、中层、深层无机碳和有机碳的碳密度图,分析了无机碳、有机碳的分布范围和特点以及它们在不同土壤类型中的分布特征。结果表明研究区单位土壤无机碳平均储量为2881.333t,平均密度为0.720 kg/m^2,单位土壤有机碳平均储量为43128.667t,平均密度为10.782 kg/m^2;有机碳和无机碳在表层、中层和深层土壤中含量分布趋势一致;在不同土壤类型中含量分布趋势也一致,均为滨海岩土中最高,粗骨土中最低。Based on the data of organic carbon and total carbon in the surface and deep soil obtained from the multi-target regional geochemical survey of Wenzhou in Zhejiang,the“unit soil inorganic carbon amount”and its densities in the surface soil layer(0~0.2 m),middle soil layer(0~1.0 m)and deep soil layer(0~2 m)were calculated by linear model.The“unit soil organic carbon amount”and its densities were obtained in surface soil layer(0~0.2 m),middle soil layer(0~1.0 m)and deep soil layer(0~2 m)by the exponential model.Furthermore,the density of inorganic carbon and organic carbon of surface,middle and deep soil layers were mapped,and their distribution ranges and characteristics were studied for different soil types.The results show that the“unit soil inorganic carbon amount”in study area is 2881.333 t and the average density is 0.720 kg/m^2,while the“unit soil organic carbon amount”is 43128.667 t and the average density is 10.782 kg/m^2.The distribution of organic carbon and inorganic carbon in surface,middle and deep soil layers shows the same trend.Simultaneously,inorganic and organic carbon storage in different soil types also shows the same features,i.e.,the highest value is in the littoral rock soil and the lowest value is in the coarse bone soil.
