Abstract:: Three slope protection models such as hole shape soil prepared seedin g (HSSPS),net-suspended spray seeding (NESS),framework seeding (FS) were selected as study objects in this paper.According to the vegetation of the frequency and the relative density,each of the effectiveness and the vegetation back with a species of different slope protection models were classified by the clustering analyisis.The results indicated NESS model is the best one,the next is the HEEPS model,and the poorer one is the FS model with regard to protection effectiveness.Artificial vegetation such as Medicago sativa L., Caragana korshinskⅡ Kom., Coronilla varia L.and Lolium perenne L.are dominatn species.Competition of different species between the natural vegetation and artificial vegetation is fierce in HSSPS model.Artificial planted Medicago sativa L is the main species in NESS model,its relative density is far higher than Lolium perenne L.,Artificial vegetation Caragana korshinskⅡ Kom.,Coronilla varia L.and Medicago sativa L are the dominant species,natural vegetation such as Corydalis bungeana, Lespedeza bicolor Turcz.,Carduuscrispus L.are all concomitance species in FS model.
