[Objective] 5 typical side slope plant communities that had been revegetated for 8 years on a section of Daguang highway, that is Fugou-Xiangcheng highway (abbreviated as Fuxiang highway), were selected as research objects. Their stability were measured to provide theoretical foundation for the sustainable landscape construction.[Methods] The data of vegetation community and soil were surveyed and measured. 15 factors of 4 indices involved plant community stability, including species diversity, communities biomass, soil moisture and soil nutrient were used to evaluate the community stability with subordination function method.[Results] Lolium perenne + Trifoliumrepens Linn + Melia azedarach vegetation community had the highest scores of species diversity index, biomass of vegetation communities index and soil moisture index, while the Bidens pilosa + Lolium perenne vegetation community had the highest soil nutrient index. The rank of the 5 typical vegetation communities was Lolium perenne + Trifoliumrepens Linn vegetation community + Melia azedarach vegetation community > Bidens pilosa + Lolium perenne vegetation community > Lolium perenne + Medicago sativa vegetation community > Bidens pilosa + Lolium perenne + Medicago sativa vegetation community > Euonymus fortune vegetation community.[Conclusion] Based on the stability analysis of these vegetation communities, it was concluded that Melia azedarach, Lolium perenne, Trifolium repens and Medicago sativa were the first selected plants for the sustainable landscape in Fuxiang highway. It is better to enrich the vegetation community layers and plant furnishing mode, such as Melia azedarach/Broussonetia papyrifera/Ailanthus altissima/Robinia pseudoacacia + Lolium perenne + Medicago sativa, Melia azedarach/Broussonetia papyrifera/Ailanthus altissima/Robinia pseudoacacia + Amorpha fruticosa + Trifolium repens + Lolium perenne, Melia azedarach/Broussonetia papyrifera/Ailanthus altissima/Robinia pseudoacacia + Amorpha fruticosa + Medicago sativa + Lolium perenne.
