石羊河中游荒漠绿洲区土壤水分的分布特征

Shuitu Baochi Xuebao, 2007
通过田间实验,研究了不同土壤层颗粒组成、土壤水分的分布特征及不同土壤层间土壤水分的关联性。结果表明：（1）土壤颗粒组成决定了不同土壤层的持水性能,是导致土壤水的分布及运动方式发生变化,影响水分在土壤中滞留时间的根本原因,土壤层中的砂砾所占百分数越大,粘粒含量就越少,含水率就越小,壤土中的土壤水分滞留时间远大于砂质土壤。（2）试验区3m内土壤层可分为水分散失带、水分滞留带和水分过渡带,水分滞留带是土壤水分暂时贮存的重要土层,也是为植被提供深层土壤水分的直接来源,对植被的生长及农作物生产有重要的影响 ...
