Abstract

The conflict between humanity and nature has recently gained prominence due to the ongoing development of human society and rising tensions caused by man-made conditions. Therefore, the Tibetan Plateau, known as the ecological environment’s treasure house, is now experiencing environmental degradation and losing biodiversity, which has increased its ecological vulnerability. This study quantitatively analyses the environmental evolution and driving factors of the ecological vulnerability of the Tibetan Plateau from 2005 to 2020. The three aspects chosen for evaluation factors are social economy, natural environment, and social response. The weights of the parameters that were chosen using the AHP method are then evaluated using a PSR model that is constructed. The vulnerability map for the local ecological environment is then created using the GIS model. Additionally, the GeoDetector method is used in the study to examine how the spatial-temporal differences change and the variables that influence those changes. The findings demonstrate that the interaction between vegetation cover, altitude, precipitation, and local human activities is the primary factor causing ecological vulnerability. And this study will advance ecological protection and development of the Tibetan Plateau, and make new strides in the study of topics.
