[Objective]The aim of this study is to assess and model the vulnerability of social-ecological systems in the Beipanjiang River Basin, which is of great significance for building an ecological barrier in the upper reaches of the Pearl River and realizing sustainable development in the basin. [Methods]An explicit spatial vulnerability model was used to construct an evaluation index system from three dimensions, namely, exposure, sensitivity, and adaptive capacity, to assess the vulnerability of the Beipanjiang River Basin, and to simulate the vulnerability scenarios under different decision-making risks using an ordered weighted average operator. [Results](1)From 2000 to 2020, the vulnerability of the Beipanjiang River Basin decreased significantly, with the proportion of highly vulnerable areas decreasing from 13.82% to 8.37%, and the proportion of low vulnerable areas increasing from 10.66% to 17.62%.(2)The overall vulnerability of social-ecological system in the Beipanjiang River Basin in the past 20 years was at a medium level, accounting for 32% on average, and the spatial variation showed the distribution pattern of low level in the northwest and southeast, high level in the middle.(3)From the perspective of scenario simulation analysis, the attention should be paid to the stress of risk environment, the construction of ecological environment protection and adaptive capacity should be strengthened, and both development and protection in the economic priority model should be emphasized, green infrastructure to ease systemic fragility should be strengthened. [Conclusion]The degree of vulnerability of the Beipanjiang River Basin is significantly reduced, and the results of the scenario simulation can meet the needs of watershed development under the guidance of different policies and provide theoretical references for the ecological restoration of the land space in the Beipanjiang River Basin and the sustainable development of the region.
