According to vegetation succession stage and plant growth form in the ecological restoration process in the hilly-gullied Loess Plateau

erosion-resistant species may be divided into annual herb plant

perennial rhizome grass plant

perennial rootshoot herb and subshrub plant，shrub plant

and arbor plant.The changes of the erosion-resistant species in the ecological restoration process show that annual herb plant and perennial rhizome grass plant have higher ability to adapt soil erosion environment and a certain extent of effect to prevent soil erosion，while shrub plant and arbor plant have weaker ability to adapt soil erosion environment but very strong effect to prevent soil erosion. The ability of perennial root-shoot herb and subshrub plant to adapt soil erosion environment is in the middle，with their ability to prevent soil erosion is superior to annual herb and perennial rhizome grass plant

but inferior to shrub and arbor plant.The recommendadons on the practice of afforestation based on the restoration of natural herb vegetation are put forwarded.
