| 摘 要： | 棕漠土和灌淤土在塔里木盆地西缘洪积平原上广泛分布,文章选取这两种类型的土壤作为研究对象,测试分析了在不同的土壤层位有机碳和全氮的含量,探讨了有机碳和全氮含量、以及它们与粒级组之间的相关关系。研究结果表明:洪积平原两种土壤剖面在0～100cm层位上有机碳和全氮含量随着土壤层位深度的增加而降低,而在40～60cm层位上两种土壤的有机碳和全氮含量差值达到最大值,并且整个剖面上有机碳和全氮含量变化呈正相关的关系。

| Abstract: | Brown desert and alluvial soil are widely distributed in the alluvial plain of the western edge of Tarim basin. These two types of soil are choosed as research objects in this paper. We measured and analyzed the contents of organic carbon and total nitrogen in different soil layers and discussed the correlation between organic carbon content and total nitrogen content and between the contents sets of soil particle size. The results show that:contents of the organic carbon and total nitrogen of the two soils decrease with increase of depth in the interval 0 to 100 cm in the section of the diluvial plain. However, the difference of the organic carbon and total nitrogen content is biggest at the interval 40 to 60 cm. In addition, organic carbon and total nitrogen content were positively correlated throughout the section. |
