Research of the water conservation engineering and management techniques on the Qinghai-Tibet Railway

Qinghai-Tibet Railway is located in the plateau permafrost with the special circumstances.The soil erosion is complex along the railway line.In order to explore the integrated governance model of the soil and water conservation for the linear development and construction projects on the plateau permafrost zone,based on the operation of the Qinghai-Tibet Railway and the idea of ecological protection first,tracing the Qinghai-Tibet Railway construction characteristics,the paper analyses the soil and water conservation engineering and management techniques and describes the methods of the water and soil protection of the Qinghai-Tibet railway system research and analysis.
