河北省南部平原区土壤有机碳储量估算

An estimation of oil organic carbon reserves in the southern plain of Hebei Province

土壤中碳储量的估算是当前研究全球大气碳循环和变化的基本问题。本文以河北省多目标地球化学调查所获大量土壤数据为基础,在GIS平台中采用中国地质调查局提出的"单位土壤碳含量"概念,按土壤类型和土地利用分类两种划分方式计算了河北省南部平原区土壤有机碳储量。结果表明,河北省南部平原区土壤有机碳储量为819402498t,平均有机碳储量为13206.1t/km2。

At present, the estimation of soil carbon reserves constitutes a basic problem in studying the global atmospheric carbon cycle. Based on soil carbon data obtained by multi -purpose geochemical survey in Hebei Province, the authors calculated the soil carbon reserves accurately according to soil types and land use classification so as to estimate soil carbon reserves in the southern plain of Hebei Province, with the adoption of the concept of unit carbon content in the GIS platform. The results show that the soil organic carbon reserves in the southern plain of Hebei Province come to 819402498 t, and their average soil organic carbon reserves are 13206.1 t/km^2.
