| 中文摘要: |
| 研究了阿尔泰山地土壤有机碳的组成及分布变化规律?研究认为?随着海拔高度的增加?土壤的易氧化有机碳逐渐减少?其氧化稳定系数?即Kos 值逐渐增大?具有一定的垂直地带性；虽然土壤有机碳总量随海拔高度的增加而增加?但其有效肥力却逐渐减少?由低海拔到高海拔?土壤有机质逐渐以累积为主。 |
| 英文摘要: |
| Study was made on soil organic carbon composition and distribution law in Altai Mountains．The results showed that the readily oxidizable carbons were decreasing?and the Kos value was increasing with altitude raise．All of these were distributed vertically in zonality．Although the total soil organic carbons increased with the altitude rising?but the effective fertility decreased．From the foot to the top of the mountains?the soil organic matter accumulated gradually． |
