摘　　要：根据生态承载力、生态足迹计算模型,对甘南藏族自治州生态承载力等相关指标进行测算,并对其生态压力水平进行分析。研究表明:甘南州人均生态承载力变化较小,人均生态足迹变化呈现倒“U”型特征。目前条件下,甘南州处于生态盈余状态,但随着居民消费水平的提高和消费结构的不断改变,生态系统可持续性面临挑战。Based on the calculation model of ecological carrying capacity and ecological footprint,this study calculates the ecological carrying capacity and other related indicators in Gannan Tibetan Autonomous Prefecture,and analyzes its ecological pressure level.The research shows that the per capita ecological carrying capacity of Gannan Prefecture has little change,and the per capita eco-logical footprint changes in an inverted"U"shape.At present,Gannan Prefecture is in an ecolog-ical surplus state,but with the improvement of residents'consumption level and the constant change of consumption structure,the sustainability of the ecosystem is facing challenges.

关 键 词：黄河源区 生态承载力 生态功能区 生态压力 甘南
