Abstract：In order to investigate and monitor the positive effects of soil bioengineering technology on ecological restoration of river in local areas, species like Salix alba var. tristis, Amorpha fruticosa L. and S. matsudana were selected as the experimental plants applied on the 40m-length artificial slope. By summarizing ecology characteristics of these species, we valued the suitability of soil bioengineering carried on the slope land. Results indicate that: under the measure of living cutting, the diameter of S. alba var. tristis and S. matsudana vary greatly; the average diameter at breast height（DBH）of S. alba var. tristis is 22.5% higher than that of S. matsudana; there is a big difference between the height of S. alba var. tristis and A. fruticosa L, the average DBH of S.alba var. tristis is 33.3% higher than that of A.fruticosa L. While under the measure of brush mattress, the average DBH of S. alba var. tristis and A. fruticosa L. vary significantly；the average DBH of A. fruticosa L. is 18.2% higher than that of S. alba var. tristis; there is no significant difference in height among these three species. Both S. alba var. tristis and S. matsudana show good adaptability under measures of living cutting and brush mattress, while A. fruticosa L. under the measure of brush mattress performs the best.
