中文摘要	以渭北旱塬小麦地的填方区、原状区和挖方区为研究对象,研究了小麦地不同修整区域深0～600cm范围内土壤水分的分布规律.结果表明,地下0～200cm土壤水分变化较快,在春季,该层土壤含水量挖方区>原状区>填方区;地下210～450cm处,同季节测定的不同修整区土壤水分差别不大,但该层秋季的土壤水分含量要比春季约高3至4个百分点;地下460cm以下受降水影响较小;在秋季,填方区土壤水分可以恢复到地下450cm.结论,对于旱塬无灌溉区,挖方区更有利于冬小麦的生长.
英文摘要	The author studies the patterns of the soil water content distribution in the depth of 0-600cm under the filled, original area and excavation area of wheat land in Weibei arid region. The result showed that in 0-200cm, change in the soil water content was fast and the sequence of the soil water content of different zones in spring was as follows: the excavation area > the original area > the filled area. In 210-450cm, although the difference of soil water content in different zones in the same period was not significant, the soil water content of the wheat land in autumn was 3-4 percent higher than that in spring. Below 460cm, the influence of precipitation on the soil water content of the wheat land was small. In autumn, the soil moisture could go back to the depth of 450cm under ground. The conclusion was that the excavation was most favorable for the growth of wheat in the Weibei arid area without any irrigation practice.
