摘　　要：构建了西藏草地生态承载力评价指标体系,以班戈县为例,采用层次分析法和模糊综合评价法,从资源承载力、环境承载力、生态抵御力和资源-环境承载压力等方面综合评价草地生态承载力。结果表明,班戈县草地生态承载力为低度超载状态,生态抵御力有待提高,草地退化治理、防害抗灾、土地环境是影响班戈县草地生态承载力的重要方面。The evaluation index system of grassland ecological carrying capacity in Tibet was constructed.Taking Bange County as an example,the analytic hierarchy process(AHP)method and the fuzzy comprehensive evaluation method were used to comprehensively evaluate the grassland ecological carrying capacity from the aspects of resource carrying capacity,environmental carrying capacity,ecological resistance and resource-environment carrying pressure.The results showed that the grassland ecological carrying capacity in Bange was in a low overload state,and the ecological resistance needed to be improved.The grassland degradation management,disaster prevention and resistance and land environment were the important aspects that affected the grassland ecological carrying capacity in Bange County.
