| 摘 要： | 通过对内蒙古西部黄土丘陵区土壤水分的初步研究,表明:该区土壤水分的垂直动态分布分为三个不同层次,即:水分不稳定层(0～40cm);中间过渡层(40～100cm);水分相对稳定层(100～200cm);旱作土壤水分的动态变化与降雨的变化基本一致;作物对土壤水分的消耗主要是当年降雨。

| Abstract: | Through the preliminary study of soil moisture in loess hilly areas of the West Inner Mongo-lia, it was concluded that the dynamic distribution of soil moisture in vertical direction can be di-vided into three section, i. e., the fluctuation section (0 - 40cm), the middle transformation section(40- 100cm), the relative stable section (100 - 200cm). There is agreement between the dynamicchanges in soil moisture and the changes in rainfall in arid farmland. |
