Abstract:In order to seek the best method and suitable plant varieties for ecological restoration of high steep slope, the technical schemes for the ecological restoration of mountainous slopes along the Mile-Mengzi Railway in high altitude area are selected and compared. The construction technology and key technical features of climbing vine ecological restoration, and the screening, introduction, promotion and application effects of local climbing plants are introduced in detail. Through the comparative experiments of climbing plants in the high altitude area, a plant configuration model for mountain ecological restoration is established by screening from a large number of climbing plant varieties in Yunnan region to find the best variety suitable for ecological protection of railway mountains, which provides a new technical way of mountain ecological restoration for railway engineering in high altitude area.
