Abstract We evaluated the ecological restoration effects of different revegetation patterns based on analyzing soil chemical characteristics of planted vegetation of arbor(Populus simonii,Pinus sylvestris mongolica, Pinus tabulaeformis and Larix principis-rupprechtii)and shrub species(Caragana korshinskii,Hippophae rhamnoides and Salix cheilophila)distributing on the two sides of highway from Yuanbaozi to Youweizi regions of Youyu County in Shanxi Province.The results show that:(1)the ecological restoration effects of different revegetation patterns are significantly different,the ecological restoration effects of mixed forests are much better than those of the pure forests;(2)shrubs of Caragana korshinskii,Hippophae rhamnoides and Salix cheilophilaplay important roles in the process of ecological restoration in this area,especially leguminous species of Caragana korshinskii is better than that of non-leguminous species;(3)arbor(Pinus sylvestris mongolica and Pinus tabulaeformis)and shrub species(Caragana korshinskii,Hippophae rhamnoides and Salix cheilophila)with strong ecological adaptability of drought and cold resistance could be used as the priority species for future revegetation in this region;(4)the high soil quality is good for developing organic agriculture in this region.
