基于浙江省主要农作区土壤调查获得的样品与测试数据,采用指数模型方法计算了表层、中层、深层土壤有机碳的储量及平均密度,按地区分布、土壤类型、土地利用方式对其作了比较分析。浙江农作区0~0.2m、0~1.0m、0~1.8m不同深度土壤的有机碳储量分别为1.13×108t、3.78×108t、4.93×108t,平均密度分别为0.31×104t/km2、1.03×104t/km2、1.35×104t/km2。有机碳储量在林地与耕地分布最高,分别占总量的72.87%与14.91%;在水稻土与红壤中共占83.54%。平均有机碳密度在林地与耕地最高。与国内其他地区相比,浙江土壤碳库具有较大固碳能力和增长潜力。

This paper uses soil samples and test data from farmland in Zhejiang Province to determine soil organic carbon storage and the average soil carbon density in the surface layer（0~0.2m）,middle layer（0~1.0m）,and deep layer（0~1.8m） using the exponential model method,and sets the results in the context of the distribution of soil types and land use in the region.Soil organic carbon storage in the surface,middle,and deep layers was 1.13×108,3.78×108,and 4.93×108 t,respectively,and the average soil carbon density was 0.31×104,1.03×104,and 1.35×104 t/km2,respectively.Organic carbon storage was higher in woodlands and cultivated land at 72.87% and 14.91%,respectively,and in the paddy soil and red soil was around 83.54%.The average soil carbon density was also high in woodlands and cultivated land.In contrast to other provinces,the soil carbon storehouse has more fixed carbon functions and increased potential for fixing carbon in Zhejiang Province.
