| Abstract: |
| Due to the climatic characteristics of dry-hot area,the movement of soil water in different periods under ground-slipcover with sands and film were preliminary studied.Observed data of soil water from 2003 and 2005 showed that under ground-slipcover,the soil water above the surface layer 40 cm is change with rainfall and evaporate intensity,but the soil water under the deep layer 60 cm is stabilization.Through the covering with film and sands,the soil water has increased with the different deep.The cover with the film is the best method,the increase amplitude can be 5%,then the second one is the covering with sands,which increased 2.612% than the comparison. |
