Water conservation in arbor-shrub-hedge-gutter is a new method of controlling soil erosion and water conservation. A series of indoor experiments about the soil moisture movement of gutter on the condition of water conservation in arbor-shrub-hedge-gutter were conducted . The experimental results indicated that that advancing distance of horizontal and vertical wetting front increase according with the infiltration time, the advancing speed of wetting front decrease while the infiltration time increases, and the relationship between the advancing distance of horizontal and vertical wetting front and the infiltration time appears obviously logarithmic relationship. The above results will offer reference for defining technical element of water conservation in arbor-shrub-hedge-gutter.

Slope length is one of the important factors for slope-runoff and slope sediment yield. In order to research the role of slope length on slope erosion in the test area, the rainfall runoff observation experiments of different slope length were conducted. The experimental results indicated that runoff volume and erosion amount showed a gradually increasing trend with the increase of slope length.
