This paper assessed the quality of different vegetation rehabilitation models in the north mountain region of Lanzhou City by related evaluation index.The results show that the method of S value is an effective method for selecting vegetation rehabilitation in arid area.The model of contour plat form+fish-scale-like pits+ecological pad cover+ artificial bush communities(K or shinsk peashrub

Platy cladusorientails

Tamarix austromongolica Nakai

Ammopiptant husmongolicus)is the most effective vegetation rehabilitation method in the irrigation area.For no irrigation afforestation area

the model of V type contour plat form+fish-scale-like pits+plastic covering+natural plant communities+Reaumuria is the most effective path in south slope(semisunny slope

ridge area)

and the model of fish-scale-like pits+plastic covering+natural plant communities+Reaumuria+K or shinsk is the best model in shady slope(semishady slope).The model of fish-scale-like pits+natural plant communities+Tamarix austromongolica Nakai is a good way in gully area.Hill closure+ natural plant communities is an effective revegetation method for all cases.
