Abstract In order to build a stable and highly efficient artificial vegetation community, the enactment of plant selection and aim of vegetation community in the Thicklayer Foreign Soil Spray Seeding Technique must be scientificaly defined.The principle of aim enactment of vegetation community is put forward that ensuring the slope stability as premise should be harmonious with the surrounding environment and requires little management.Based on this principle,the eco-stability of different community types and the affecting factors are analyzed,and it is proposed that plant selection give prioring to native species and initial density should be decided reasonably accoring to the restoration aim.The slope stability and the quality of sprayed foreigh soil layer are also important factors which will affect whether the artificially restored vegetation community can successfully develop into the aimed one.
