Abstract: Global changes have a profound impact on ecosystems. If the disturbance caused by global change exceeds a certain degree, ecosystem resilience will be reduced, extreme events will be frequent, and ecosystem services will be degraded or even lost. Quantifying the risks of global change and developing appropriate adaptation strategies is an important way to deal with the risks of global change. Global change may reduce ecosystem resilience, leading to increased vulnerability and the risk of ecosystem degradation. The risk of ecosystem degradation is currently quantified mainly by the safe operating space assessment method based on planetary boundary theory. Understanding the concepts of ecosystem resilience, vulnerability, planetary boundaries, and safe operating spaces and their relationships is an important prerequisite for addressing the risks of global change. By summarizing the relevant theories of ecosystem vulnerability, we combined the concepts related to ecosystem resilience and vulnerability, global change risk and human adaptation, proposed a conceptual framework of ecosystem global change risk and human adaptation based on the vulnerability theory. Based on the logic of this proposed framework, we successively introduced the characteristics and mechanism of global change interference on ecosystem vulnerability, elaborated the assessment theories and methods of ecosystem vulnerability, and how to adopt human adaptation measures to alleviate the risk of global changes, aiming to provide ideas for coping with the risk of global change.

Key words: vulnerability, resilience, global change, planetary boundary, safe operating space, human adaptation
