| Abstract: | Taking an evergreen broadleaved forest in Huitong County of Hunan Province as the research object,this article has analysed and determined the physical characteristic of water in soil,the water-holding Characteristic of litter layer,the characteristic of water infiltration into soil,the characteristic of rain-drop size distribution,and the characteristic of rain kinetic energy.The results indicate that the evergreen broadleaved forest ecosystem plays an important role in preventing soil from rain eroding and in conserving water resources. |

| Keywords: | evergreen broadleaved forest soil water retention soil permieability rainfall kinetic energy |
