| 摘 要： | 为了开展植被恢复试验，对干热河谷土壤水分的动态变化规律进行初步研究。结果表明随海拔高度增加，干热河谷干季土壤水分呈逐渐增加趋势。干季相同海拔高度不同土地类型土壤含水量均较低，土壤含水量都低于 8% 。层间变化由于受降雨入渗分布与土壤水分向上蒸发的综合作用基本表现为增长型。利用变异系数对土壤水分的层间变化进行了分析和层次划分。

| Abstract: | The pilot study on soil moisture dynamic variation law in dry season's in the dry-hot valley areas has been done in order to develop the vegetation restoration experiment.The results show as follows: The soil moisture in dry seasons increases gradually with the increase of altitude.The soil moisture in dry seasons in different land use type areas at same altitude is lower and its quantities are all below 8%.The vertical changes of soil moisture content influenced by the distribution of rainfall infiltration... |
