Review on hillslope soil water movement and transformation mechanism on the loess plateau

Soil water is the primary limiting factor for crop growth,vegetation rehabilitation and eco-environment construction Hillslope soil water movement and transformation is reviewed,including rainfall infiltration and soil water redistribution,soil water transformation,and soil water dynamic change For a successful project of vegetation rehabilitation,soil-plant-atmosphere on the hillslope should be considered to be a physical continuum,and its interfaces of water movement and transformation should be studied based on the processes and mechanisms of atmospheric water,surface water,plant water,and soil water.
