Analysis and discussion on several cases of ecological restoration engineering of rock slope in Shenzhen

With the development of national infrastructure, a large scale of artificial wound has been made by roads building and resources exploitation. Under the natural environmental conditions of Shenzhen,bare rock(especially hard rock)surface is difficult to recover relying on nature forces.Manual intervention has been an effective technical approach to recover the ecology of rock slope.This article focuses on the ecological protection technique, describing a number of project cases on the artificial ecological restoration of rock slope. Combined with the characteristics of the slope,slope protection engineering methods and techniques,the local slope species and artificial soil have been expounded. What is more, some key technical issues, like slope characteristics and slope protection techniques, substrate design and the ratio vegetation have been attached great importance to.These conclusions have much promotion on the deepening of work of slope ecological restoration in Shenzhen,the innovation of slope ecological restoration engineering technology and the improvement of the engineering design level.
