Construction of Caragana korshinskii vegetation and studies on the excessive depletion and regulative recovery were performed with the conjunction of engineering and biotic measures. The results showed that the optimum stereoscopic collocation model with the level-step was Caragana korshinskii-Clinelymas dahuricus , Caragana korshinskii-Mililotus suaveolens and Caragana korshinskii-Achnatherum splendent, the optimum one by level-gouge was Caragana korshinskii-Achnatherum splendens and Caragana korshinskii-M...
