Engineering Revegetation——New Ecological Restoration Techniques for Especially Difficult Sites

The development and construction projects have led to a large number of artificial slopes and ecological damages.The ecological restoration has greatly accelerated the control process of soil erosion,and highlighted the great role of soil and water conservation in the construction of ecological environment.However,in some especially difficult sites,general ecological restoration technology can not work and meet the people's requirements.Therefore,the engineering revegetation technology for the difficult sites will be widely studied and applied.The concepts,technical systems and application types of the engineering revegetation technology are analyzed and discussed in this article.
