Abstract: The main impacts of desert vegetation on soil hydrological processes are briefly reviewed in order to highlight needs and perspectives for research and management goals. This review is based upon the distinct influences of desert vegegtation on soil hydrological processes. Precipitation, as the sole source of water replenishment in the semi-arid area, plays a pertinent role in sustaining the desert ecosystem. The objective is to describe and model the transportation of soil moisture between the elements of this integrated artificial system and to understand how these transporting paths influence and are influenced mainly by vegetation patterns and stability. The aim of the activities is to give a theoretical answer for the basic scientific problems of how the soil water dynamics influencing the vegetation construction and pattern in the establishment of rainfed artificial vegetation and the ecological recovery of desert area in western China.

Key words: soil water, desert ecosystem, rainfed vegetation
