Abstract:

By constructing the evaluation indicator system and evaluation method of ecological security,the ecological security index,state and pressure indicators of forest,grassland,wetland,snow area and desert ecosystems of the Qinghai-Tibet Plateau from 2015 to 2021 were calculated.The results showed that the ecological security level of the Qinghai-Tibet Plateau was between 0.6 and 0.8,and the ecological security index of Tibet was higher than that of Qinghai.Based on this,the paths to improve the ecological security of the forest,grassland,wetland,snow area and desert ecosystems on the Qinghai-Tibet Plateau were put forward,also the strategy to ensure the ecological security of the Qinghai-Tibet Plateau was pointed out.

Key words: the Qinghai-Tibet Plateau, ecological security, indicator system, the improving paths
