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。
Based on the data of soil organic carbon in 0 ~ 60 cm soil layer of 16 soil profiles in 4 typical monitoring sections of the lower reaches of the Tarim River in 2005 and based on the past survey data and literature data, The principle has studied the impact of downstream desertification on soil organic carbon, and discussed the possible impact of ecological restoration on organic carbon. The results showed that desertification had a great influence on soil organic carbon in the lower reaches of the Tarim River. From the upper reaches to the lower reaches of the Tarim River, the contents of organic carbon in the upper (0 ~ 50 cm) soil showed a decreasing trend. , 3 to 4 times as many as the test cadre, about 1 times more than the Kao-Khan area in the UK and the Soviet Union. In the process of ecological restoration, the content of soil organic carbon will increase remarkably, but the increase of soil organic carbon in the lower reaches of the Tarim River will be a slow process.
