| 摘 要： | 基于辽河流域多目标地球化学调查取得的土壤表层和深层有机碳和全碳数据，探讨辽河流域土壤碳储量计算方法，分析辽河流域碳密度的分布特征.对辽河流域5.23×104 km2土壤碳储量计算表明，深层（0~1.8 m）土壤碳储量为860.50×106 t，中层（0~1.0 m）为538.30×106 t，表层（0~0.2 m）为138.76×106 t；辽河流域土壤深层碳密度为16.45×103 t/km2，中层为10.28×103 t/km2，表层为2.65×103 t/km2.分别根据土壤类型、地质单元、生态系统和土地利用类型的划分方式计算土壤的碳储量，为土壤碳循环研究与环境效应评价提供了科学依据.

| Abstract: | Based on the data of organic carbon and total carbon in both surface and deep soil by the multi-purpose geochemical survey in Liaohe Basin,the carbon reserves in the soil of Liaohe Basin are calculated.The distribution of carbon density is analyzed.According to the calculation,in the area of 52.3 km2,the carbon reserves in deep level are 860.50 Tg;those in the middle level,538.30 Tg;while in the surface,138.76 Tg.The soil carbon density in deep level is 16.45 Gg/km2;that in middle level,10.28 Gg/km2;while t... |
