  摘要: 为分析坡地土壤水分运移规律，以陕北黄土高原米脂县孟岔村红枣基地典型坡地为研究对象，应用Hydrus-1D模拟了坡地土壤水分运移过程。结果表明，秸秆覆盖的坡面保水保墒效果明显，且覆盖秸秆和施保水剂对坡面降雨的调蓄有一定作用。降雨后不同深度土壤水分变化的幅度有明显差异，浅层水分变化的幅度大于深层。利用软件模拟分析方法能够较合理地模拟土壤水分一维动态变化过程，可以作为一种预测手段，对土壤水分动态变化问题的研究有一定的参考价值。 The soil water movement in typical slope of the Mengcha Village, which is located in Mizhi Town, Northern Shaanxi Province, was analyzed by the Hydrus-1D model. The results showed that the straw mulching slope had obvious water-holding effect, and it could control the rain storage as well as the water-holding applying slope. The change rates in different depth of soil moisture were significantly different, shallow soil moisture variation is larger than the deeper. Hydrus-1D can simulate soil water movement effectively in the vertical direction as a prediction way.
