Four typical sections of red sandstone slope along Shaoguan-Ganzhou expressway were selected tostudy the ecological protective effects of the grass-shrub vegetation technology on protection of red sandstoneslope.Plots were deployed to investigate the species compositions with different grass-shrub ratio.In addition

the number

height and frequency of shrub were also surveyed and recorded.The indexes regarding relative abundance

relative height

relative frequency

important value of plots

the shrubs were determined todescribe the compositional features and quantitative and ecological characteristics of the plant communities inthe test area.The results indicated that grass-shrub vegetation technology was more readily adaptable for redsandstone with poor surface soil

which is prone to weathering and erosion.Legume species grow well in thecircumstance with pool soil by nitrogen fixation and therefore played an important role in ecological restoration of vegetation on the study area.A certain ratio of local native shrubs

legume and grass could build astable plant community on red sandstone slope

showing good protective effects.
