摘　　要：雅砻河源区是西藏"两屏四地"战略格局的核心区域,研究其生态承载力意义重大。通过构建基于国家公顷评价标准的改进生态足迹模型,分析雅砻河源区2007~2014年的生态承载力现状。结果表明,基于国家公顷的生态足迹模型能有效反映源区生态承载力现状,且评价结果优于传统评价模型的评价结果;源区生态足迹逐年上升,生态承载力逐年下降,源区处于生态盈余状态但生态盈余量呈下降趋势,表明源区生态环境持续恶化,对此提出了相应保护措施,研究成果可为源区规划及保护提供依据。As the key protect zone of ＂four two-screen＂ strategy of Tibet area,the research of ecological carrying capacity is significant in the headstream region of Yalong river.In this study,an improved ecological footprint model based public hectare evaluation criteria was applied to analyze ecological carrying capacity of headstream from 2007 to 2014.The results demonstrate that the proposed model can reflect the true condition of headstream region well,and the results are better than that of the traditional method;the ecological footprint appears upward trend and the ecological carrying capacity has downward trend of headstream region of Yalong River;this area was in the status of ecological surplus,but it shows a downward trend.All of those results show that the ecological environmental problems continues to be deteriorated.So,some protective measures are proposed for those problems,and the result can provide a basis for planning and protection of headstream region.
