中文摘要	在2005年所测的塔里木河下游4个典型监测断面上16个土壤剖面0~60 cm土层土壤有机碳数据的基础上, 结合过去的勘测数据及文献资料, 依据"时空互代"原理研究了下游荒漠化对土壤有机碳的影响, 探讨生态恢复对有机碳可能产生的影响. 结果表明:荒漠化对塔里木河下游土壤有机碳影响均较大;自塔里木河下游上段至下段, 上层(0~50 cm)土壤有机碳含量呈下降趋势;阿克墩地区土壤有机碳储量比英苏、考干的多3~4倍, 英苏地区的比考干地区的约多1倍. 在生态恢复过程中, 土壤有机碳含量会显著增加, 但是, 在塔里木河下游土壤有机碳的增加将是一个缓慢的过程.
英文摘要	Based on data from soil organic carbon of 112 soil samples collected from 16 soil profiles located at four monitoring sections in the lower reaches of the Tarim River in southerm Xinjiang, the soil organic carbon of desertification and ecological restoration was analyzed using "substitution method of space for time".The results showed that desertification badly influenced the soil organic carbon. Along the different monitoring sections in the lower reaches of Tarim River(from the upper part to the lower part), the soil organic carbon contents had a descend trend. Soil organic carbon storage in Akdun was more than 3-4 times than that in Yinsu and Kaogan, and in Yinsu it was more than 1 times than that in Kaogan. The soil organic carbon content has been risen during the ecological restoration process. Relatively, the longer the years of ecological restoration was, the higer the soil organic carbon content was. However, it was a slowly process for soil organic carbon augment in the lower reaches of the Tarim River.
