摘　　要：本课题组对西藏扎其阿嘎土矿区植被进行了3次实地考察,遴选出适合于该矿区植被恢复的4种乡土物种:砂生槐、藏布三芒草、黑穗画眉草、白羊草;研制了一种砂生槐种子包衣的配方,并在矿区和西藏大学新校区分别试种了包衣砂生槐种子。基于上述研究成果,文章提出了一种以砂生槐种子包衣技术和藏布三芒草、黑穗画眉草及白羊草3种禾本科物种植生带技术相结合的高寒灌丛草原植被恢复的方案。Three surveys on the vegetation of Zhaqi Aga mining area in Tibet were carried out,at 2010.5,2010.6 and 2010.9 respectively.Four native species（Sophora moorcroftiana,Aristida tsangpoensis,Eragrostis nigra,Bothriochloa ischaemum）suitable for vegetation restoration in the Aga mining area were selected and a formula of coating seed of Sophora moorcroftiana have been proposed.The experiments on planting of the coated seeds of Sophora moorcroftiana were carried out in the mining area and the new campus of Tibet University.A technology for alpine grassland vegetation restoration based on the coating seed of Sophora moorcroftiana combining with belt seeding of Aristida tsangpoensis,Eragrostis nigra,Bothriochloa ischaemum was proposed.
