摘　　要：利用生态足迹模型,对2007年西藏的生态足迹进行了可持续发展的定量测算,并基于生态足迹的计算结果分析了影响西藏可持续发展能力的资源及生态因素。结果表明,虽然有着巨大生态足迹盈余,但西藏的发展仍然承受着高原生态系统脆弱与不可逆的压力该地区尚处于发展的上升阶段,生态系统承受的压力较小。Ecological footprint model was used to quantitatively estimate the sustainable development of the ecological footprint in Tibet in 2007. Based on the calculation results of the ecological footprint, the resources and ecosystem factors that affected the sustainable development in Tibet were analyzed. The results showed that the development in Tibet was confronted with the pressure of frail and irreversible plateauI-eco-system though Tibet had great ecological surplus. The area was at the developing stage and its ecosystem was confronted with small pressure.
