Abstract: The ecological red line (ERL) has become a national strategy of environmental protection in China. The ERL of Tibet should be possible to find a balance between conserving environment and the demand of economic development. For the Tibet Autonomous Region, we selected four key indicators of ecosystem services (water conservation, biodiversity maintenance, soil and water conservation, wind and sand stabilisation) and three indicators of ecological sensitivity (soil erosion, land desertification and geological disasters) to establish a targeted ERL framework. Using this approach, we found an ERL total area of 657,451 km2, accounting for 53.55% of the total assessed area. The area of grade I and II are 443,487 km2 and 214,358 km2 respectively, with dominant types of water conservation and desertification prevention. The consistent framework and standards we used at a regional scale should also be applicable to other similar plateau regions in China.
