Abstract：It is well-known that the soil and water losses in perennial bare land of slope on railway,highway,dams and ridge of field in the Loess Plateau are very rigorous as well as the eco-environment problems.In this paper,we have selected one gramineous plant-Achnatherum splendens Nevski for 10 years to do integrated(exploitation)research in introduction,planting,physiological ecological characters,soil conservation,etc..The results indicated that the plant could bear drought and infertile,resist sand blown by wind and also it had the positive effect to consolidate soil and protect slope.By using 3 planting technical practices involving seed coating bunch planting,planting by rootcuttings,planting by cuttings,Achnatherum splendens Nevski could form dense over-ground parts and extensive roots quickly.Those characters made the plant have the ability to consolidate soil,prevent earth surface runoff and soil erosion.Besides,it protected the eco-security of slope on railway,highway,dams and ridge of field.Achnatherum splendens Nevski and its corresponding planting technical system to slope rehabilitation should be used for the same regions in the western China.
