Review on resilience of human-environment composite ecosystems and its implications for research on the resilience of coastal ecosystems
Under the dual influence of global climate change and high-intensity human development,the ecological vulnerability of the man-land composite ecosystem and coastal areas affected by the interaction between land and sea systems has become more obvious.How to effectively grasp the development trend of the man-land composite ecosystem,rationally plan and regulate social and economic activities,and promote the coordinated development of man-land relations has always been a key topic in the field of sustainable development.Resilience,as an inherent characteristic of the system,plays an important role in preventing and resolving disaster risks and maintaining regional ecological security.It is an important manifestation of the sustainable development capabilities of composite ecosystems.However,there is currently no unified paradigm regarding the connotation and assessment methods of resilience of composite ecosystems,and there are large differences in quantitative assessment methods of resilience.By sorting out and summarizing existing research results,it is believed that resilience has experienced a transformation from engineering resilience,ecological resilience to evolutionary resilience,and its concept and connotation are still expanding and deepening;A summary and comparison of resilience assessment methods based on process formativeness and state summativeness found that research on comprehensive assessment of resilience as a process and outcome is still lacking;Under the concept of resilience to resist disturbance,maintain stability and coordinate development,ecosystem protection and restoration will be an important guarantee for the safety of the man-land composite ecosystem in the application of regional sustainable development.According to the analysis results of the research progress on the resilience of human-land composite ecosystems,combined with the current status and deficiencies of coastal ecosystem resilience research,it is believed that in the future it is necessary to strengthen the exploration of the connotation of coastal ecosystem resilience,improve the coastal ecosystem resilience evaluation system,and improve the coastal ecosystem resilience In-depth research will be carried out on the accuracy of resilience monitoring,promoting the integration of disciplines,and promoting the practice of effective restoration of coastal ecosystem resilience.
