摘要: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。

Abstract:Vegetation restoration of railway slope has some efficacy in restoration environment, storing water and holding soil, beautification environment, and benefit offspring, which is becoming a hot spot in the world. The topographic condition greatly changes and climate is worst in frigid and arid region, thus vegetation restoration of railway slope is a more complicated project in these regions. Progresses in the research of vegetation restoration of railway slopes were reviewed in this paper. The development foreground and technology strategies of vegetation restoration of railway slope were also proposed based on Qinghai-Tibet Railway, which will provide theory basis for construction the "green corridors" along the railway in frigid and arid regions.
