摘　　要：通过对水平梯田的分类，不同质量水平梯田的水土保持效益，以及水平梯田的质量对其抗御暴雨能力的影响３个方面的分析，说明黄土高原水平梯田的工程质量在水土保持中起着非常重要的作用。On the basis of analysing the soil and water conservation mechanism of level terrace, the classification, the soil and water conservation benefit of level terrace with different quality, and the effect on resistance to storm of level terrace by its work quality were studied. The results showed that the soil and water conservation benefit of level terrace is difficult to reach thoroughly because of that work quality; level terrace with different quality has different soil and water conservation benefit, the bigger the rainfall amount, the more discrepant the soil and water conservation benefit of different quality level terrace; in the extreme storm, the destroy of level terrace is as a result of unqualified work quality. Above all, the work quality of level terrace plays an important role in soil and water conservation.
