Ecological protection of highway slopes includes engineering restoration and bio-defense measures. The key to construct a stable vegetation restoration basis by means of net-suspended spray seeding (NSSS) or external-soil spray seeding (ESSS) is to select adaptive arbor or shrub species in an appropriate ratio. The dominant plant species adaptive to a slope environment were selected by studying the bio-attributes and plant communities with their differentiating plant ratios on the various ecological slopes, observing plant growth potential, measuring plant height as well as other plant characteristics and comparing the survival rate and key value of the respective plant species. Species such as Indigofera pseudotinctoria, Robinia pseudoacacia, Lespedeza bicolor, Dodonaea viscosa, Cassia corymbosa were the dominant shrub species that were found suitable for expressway ecological restoration and stabilization where habitat conditions were similar to that of the Jiangxi province.
