摘　　要：针对川西北高原公路边坡植被恢复过程中,没有适用于高寒环境生态恢复的植物材料和组合的问题,应用生态学实验方法,以适生于川西高原高海拔地区的本地草种—康巴垂穗披碱草、老芒麦为代表进行不同草种组合培植模式实验研究。研究结果初步表明:一年生黑麦草、多年生黑麦草、硬杆仲彬草及康巴垂穗披碱草表现最好,植被盖度相对较高,而紫花苜蓿、早熟禾则不适用于当地高寒生境条件下的公路边坡植被恢复之用。Owing to a lack of suitable plant materials and combination for vegetation recovery of bare slope in roads of Ganzi Prefecture, an experiment was carried out to study the application effects of four kinds of grass seed combination on rad bare slope at different altitudes in Kanding County. The results indicated that the combination of oat, Elymus sibiricus and Trifolium repens had the best performance at lower altitudes, the combination of annual ryegrass, meadow grass and Elymus nutans Griseb could be used at intermediate altitudes, while the combination of Elymus nutans Griseb, festuca arundinacea and oat were appropriate to recover the bare slope in high altitudes in Kangding County.
