Vegetation protection and recovery technology for plateau high-cold steppe area

Abstract

The invention relates to a vegetation protection and recovery technology for a plateau high-cold steppe area, which comprises a turf and grass seed selecting technology and a planting technology. The invention is characterized in that the planting technology adopts superior grass for vegetation recovery in an off-line project, adopts grass that livestock dislike to graze for roadbed protection and vegetation recovery, and adopts two construction technologies of turf transplantation and grass seed planting as frozen soil protecting measures. In the invention, species and planting technologies can be selected for different road area environments, the survival rate of plants at the early stage is improved, the capacities of living through the summer and winter are enhanced, the species diversity is increased, the recovery progress of vegetation at the early stage is accelerated, the operation is simple, and the working efficiency is high. The invention has the beneficial effects that a temporary steel protecting cylinder pulling technology with a steel pipe column ensures accurate positioning of a middle column, and the cost is reduced by turnover and reuse of the steel protecting cylinder.

Description

technical field [0001] The invention belongs to the field of civil engineering, and in particular relates to vegetation protection and restoration construction technology for highway and railway engineering projects in plateau alpine grassland areas. Background technique [0002] At present, Russia, the United States, Canada, Norway, Denmark and other countries only adopt transplanting, planting, cultivation, sowing and spraying techniques for environmental protection projects such as new ground vegetation protection and restoration in alpine regions. After overwintering and oversummering in the plateau alpine grassland area of ​​my country, the vegetation coverage increases slowly, and the recovery effect is poor. The Erga Highway and the Chaimu Railway Project are located in the plateau alpine grassland area. There is no precedent at home and abroad for the comprehensive supporting construction technology of road and railway engineering vegetation protection and restoratio...

After overwintering and summering in the plateau alpine grassland area of ​​my country, the vegetation coverage increases slowly, and the recovery effect is poor

The Erga Highway and the Chaimu Railway Project are located in the plateau alpine grassland area. There is no precedent at home and abroad for the comprehensive supporting construction technology of road and railway engineering vegetation protection and restoration under the conditions of the plateau alpine grassland area. There is no selection and establishment of species. Systematic discussion on technology, soil protection and monitoring and control
