摘　　要：在植被恢复过程中,草业先行是较好的水土保持策略,在实地调查分析研究九寨沟震区珍稀保护动物破坏生境植物的基础上,原位进行9个草种的盆栽试验,通过测定存活率、生物量、土壤含水率、盖度、根系鲜重、枯落物浸水容量、土壤有机质、土壤细菌多样性和土壤脲酶活性等指标,采用层次分析法进行综合评价,从中选出具有明显优势的苔草(Carex montana)、披碱草(Elymus dahuricus Turcz.)、早熟禾(Poa annua)、老芒麦(Elymus sibiricus)和鹅观草(Roegneria kamoji)作为九寨沟地震灾区植被修复过程中的推广草种。本研究为九寨沟的人工植被修复提供了理论基础和依据。In jiuzhaigou earthquake plant field investigation and analysis,combined withthe choice of 9 kinds of grass planting potted experiment,through the west survival rate,coverage,biomass,soil moisture content,root fresh weight,litter flooding capacity,selecting soil organic matter,soil urease activity and soil bacterial diversity indexes such as statistics,has obvious advantages in using analytic hierarchy process(AHP)choose Carex Montana,Elymus dahuricus Turcz.,Poa annua,Elymus Sibiricus and Roegneria kamoji as the promotion of grass vegetation restoration.This study provides a theoretical basis for artificial vagatation in Jiuzhaigou.
