Abstract:The reservoir area is an important ecologically sensitive area for urban reclaimed water environmental protection. The requirements of water source protection and management in the reservoir area put forward new requirements and challenges to the vegetation restoration of rock slope. In view of the difficulties existing in the loess bare treatment project of rock slope in the reservoir area of Qinglinjing in Shenzhen, such as large slope elevation, unstable geological structure, and limitation of external source guest soil and irrigation water in reservoir management, measures such as configuring appropriate guest soil nutrient matrix, applying Fence-Stripe guest soil spraying technology, and optimizing the species, proportions, and maintenance of plant and management techniques were taken. 12 months after the completion of the construction, a follow-up survey of ecological restoration effect was carried out. The results show that the vegetation on the high and steep slope grows well, the coverage rate of herbs plants reaches more than 95%, the surrounding naturally growing trees and shrubs begin to overflow to the slope, and the exposed high and steep rocky slope enters the natural succession of vegetation, which has achieved good social and ecological benefits.
