Theories of ecosystem vulnerability,adaptability and catastrophe based on the mechanisms of ecological succession.

With the increases in the breadth and depth of the impacts of climate change, the theories of ecosystem vulnerability, adaptability and catastrophe have gradually been widely applied in the field of ecology to explore and evaluate the sensitivity, vulnerability and adaptation of various ecosystems to climatic change. Based on such research, we can seek better ways to cope with the far-reaching impact of climatic change on ecosystems, and serve the sustainable management of national ecosystems and the construction of ecological security. Although a lot of achievements have been made to distinguish the sensitive regions responding to climatic change and potential tipping points in certain ecosystems, there are still multiple understandings and interpretations of these concepts in the academic community. To some extent, this affects the further development and application of related theories in ecological studies. Therefore, we combed the development history of related concepts, and analyzed the connotation of these concepts from the perspective of ecosystem ecology. Furthermore, we proposed a theoretical framework for ecosystem fragility, adaptability, and catastrophe based on the ecosystem evolution theory and corresponding calculation methods in order to promote the in-depth development of theories of ecosystem fragility, adaptability and catastrophe.
