铁路边坡植被恢复具有恢复生态、水土保持、防风固沙、美化环境、造福后代等特点,因此成为全球关注的热点问题。寒旱地区由于地貌高差悬殊,垂直气候差异鲜明,气候恶劣,生态环境极其敏感脆弱,其铁路边坡植被恢复更是一项复杂的工程。介绍了近年来有关铁路边坡植被恢复的研究进展,并针对寒旱地区生态环境的特殊性,以青藏铁路为例提出了寒旱地区铁路边坡植被恢复的发展方向和技术策略,为寒旱地区铁路绿色通道的建设提供一定的理论依据。
Vegetation restoration on railway slope has the characteristics of restoring ecology, soil and water conservation, windbreak and sand fixation, landscaping and the benefit of future generations. Therefore, it has become a hot issue of global concern. The cold arid region is characterized by a great difference in elevation, a sharp difference in vertical climate, a bad climate and an extremely sensitive ecological environment. The restoration of the railway slope vegetation is a complicated project. This paper introduced the research progress of vegetation restoration on railway slope in recent years. In view of the particularity of ecological environment in cold and dry regions, taking Qinghai-Tibet Railway as an example, the development direction and technical strategy of vegetation restoration on railway slope in cold dry region were put forward. Provide a certain theoretical basis for the construction of green railways in regional railways.
