天然草地是西藏面积最大、最为重要的生态系统,过度放牧、滥伐滥挖、鼠害和矿区开采等因素导致草地生态破坏严重,西藏草地生态恢复势在必行。披碱草属牧草是西藏优势乡土植物之一,具有抗逆性强、适应性广等特点。笔者在分析西藏草地生态现状、形成原因和披碱草属牧草在西藏的驯化栽培研究现状的基础上,探究其在西藏草地生态恢复中的重要作用,并提出相应的建议和对策。
Natural grassland is the largest and most important ecological system in Tibet. Due to overgrazing, deforestation and excavation, exploitation of rodent pests and mining areas, grassland ecology is severely damaged. Ecological restoration of grasslands in Tibet is imperative. Elymus forage is one of the dominant native plants in Tibet, with strong resistance, wide adaptability and other characteristics. Based on the analysis of the status quo of ecology of grassland in Tibet and the reasons for its formation and the current status of domestication and cultivation of grass in Tibet, the author explores its important role in ecological restoration of grassland in Tibet and puts forward corresponding suggestions and countermeasures.
