摘　　要：在阐明粟钙土发生特性的基础上,本文运用放射性碳方法断定了玄武岩熔岩台地上栗钙土有机质和腐殖质组成中胡敏酸、胡敏素的年龄。结果表明,我国栗钙土与其它国家的软土系同一时期的产物,它们形成于大约6000年以前。栗钙土有机质诸部分的年龄序列是:胡敏酸>胡敏素>土壤有机质。On the basis of elucidation of genetic properties of the soils, organic matter, humic acids and humin in chestnut soils on basalt platforms were dated by ^(14)C method. Results of radiocarbon dating showed that the chestnut soils of China and the mollisols in other countries of the world were the product of the same period, formed about 6000 years apo. The age of organic matter fractions from the chestnut soils was in the following: humic acids>humin>total soil organic matter.
