对西藏林芝地区米林县南伊沟景区进行生态环境承载力研究，结果表明，近期南伊沟景区生态足迹量为674.70 hm2，有效生态承载力841.13 hm2，生态盈余166.43 hm2。就景区目前及近期规划来说，开展旅游活动不会对景区生态环境产生大的影响，景区生态足迹还可进一步发展。但从生态承载力方面考虑，景区应特别注意远期规划。提出了南伊沟景区可持续发展对策。
Eco-environment carrying capacity of Nanyi Valley Scenic Area in Milin County， Linzhi area， Tibet was studied， the results showed that the recent ecological footprint of the scenic area was 674.70 hm2， effective ecological carrying capacity was 841.13 hm2， and ecological surplus was 166.43 hm2. In terms of current and short-term planning of the scenic area， tourism activities will not bring serious damages to the ecological environment， and ecological footprint of the study area can be further developed. But from the perspective of ecological carrying capacity， the scenic area needs a proper long-term planning， so the paper proposes the sustainable development strategies for the Nanyi Valley Scenic Area. It provides the theoretic basis for the reasonable planning， effective management and sustainable development of the scenic area.
