Abstract：In artificial construct process,particularly in the practices of highway,railroad,mining,water conservancy,mountainous architectures,different types of rock slope were formed.,The medium spray technique is currently in common use to recover the ecosystem of plant in rock slope,In order to achieve the goal of building objective community,we need to research the natural environment including weather,soil,vegetation,and analyse the characteristics of the slope,such as the landform of the slope,slope gradients,and the stability.In choosing the target plant,the priciples of ecosystem adaptability,pioneering,harmonizing,resistance to severe factors,as well as self maintaining,bio-diversity,sustainable stability etc.should be satisfied.The revegetation should adopt a combination of direct seeding and tree planting to help the steady rehabilitation on the rock slope.
