Abstract: Vegetation is one of effective methods for soil and water conservation. How to select
suitable vegetation species is a key problem in the practice. In this study. through 7 years
observations on the rainfall, vegetation cover, total runoff and sediment in the plots, results
indicated that the benefit of the vegetative cover on runoff and sediment dominated on all plots.
The accumulative sediment yield from bare plot was 7 times to that from Astragalus absurgens ±
Caragana korshindkii plots, also over 4 times to that from the Medicago sativa, Medicago sativa ±
Caragana korshindkii and Astragalus absurgens plots. Among all the vegetation types, Caragana
korshindkii was the most efficient in reducing the runoff, and the combination of shrub and grass
also had better effect in reducing the runoff. The accumulative runoff from bare plot was 2.57
times to that from the C. korshindkii, and over 2 times to that from M. sativa, M. sativa ± C.
korshindkii, A. absurgens ± C. korshindkii and Vicia amucena ± C. korshindkii. This study is of great
importance for the selection of suitable species for vegetation reconstruction in arid and
semi-Arid areas.
