 The condition of vegetation restoration on the slopes of Chengnan Expressway was investigated by using Line Transect Method. Meanwhile, plants information along the roadside was recorded and α diversity indexes and Important Value of plant community were analyzed as well. According to different gradient conditions, the investigated slopes were divided into three types that were represented by Roman numeralⅠ, Ⅱ and Ⅲ respectively. Data analysis results indicated that: (i) the plants that were investigated consisted of 41 families, 85 genera and 91 species, in which the amount of major four families-Leguminosae, Gramineae, Asteraceae, and Rosaceae-were the largest, constituting 44% of the number of total species.; (ii) different types of slopes were characterized by different plants with different adaptability and there were significant differences between shrub layer and herb layer. According to the results, some practical species of different slope types that adapted to certain environment were selected by α diversity indexes and Important Value. Besides, combining many previous relevant studies and the results of this paper, some advice on vegetation restoration in China was proposed to guide further research and programs in this aspect.
