摘要：

In recent years, much work has been done about covered effect and mechanism in preserving soil moisture by domestic and foreign experts (Qiao Hailong, 2006).However, there are few researches on the quantitative observation on the inhibitory effect of soil evaporation.Grass hay production system is an important biological resource.With hay as test material, this paper studied on the effect of soil evaporation by different coverage of hay and explored the mechanism.With a view to restoring grassland ecological environment and providing a theoretical basis and technological support for desertification control.
