塔里木河中游土壤分布规律及其特征研究

Research on Distribution Laws and Features of Soil in Middle Reaches of Tarim River

本文根据在 2 0 0 1年 1 0月塔里木河中游对水、土、植被等资源现状野外调查和通过定点取样分析 ,重点探讨了河岸土壤分布规律及其特征 ,并提出了土壤理化性质与生产性能评价。研究表明 :塔里木河中游长期受到减水遇旱 ,地表发行沙化和荒漠化 ,但是土壤犁地层以下土壤生态特征 ,理化性质变化不大 ,若遇到水分 ,有利于盐分淋溶下渗 ,能够得到乔、灌、草本植物正常生长发育条件 .

According to the monitoring and investigating results in Oct, 2001 at the middle reaches of Tarim River, the distribution laws and features of soil were analyzed in this article. The results were as follows: 1)there were different soil feature in different areas, which main determined . 2)We should combine the natural restoration with man-made measures to restore forest in this region and evaluate production capability of soil. these results offered scientific basis for restoring and protecting Green Corridor at the middle reaches of Tarim River.
