Research progress and prospects on grassland social-ecological systems
[Objective]The intensification of global change and human activities have increasingly exposed the complexity and vulnerability of grassland social-ecological systems(SES).Systematically analyzing the coupling and feedback mechanisms,driving mechanisms,and management strategies of grassland SES is crucial for enhancing its resilience and achieving synergies between socioeconomic and ecological benefits.[Methods]This article reviewed the current research theories,components,coupling and feedback mechanisms,driving mechanisms,and conservation management of grassland SES.[Results]The theories of grassland SES is evolving from single-discipline ecological research to complex interdisciplinary studies;soil,water,vegetation,livestock,and herders are the primary components of grassland SES;the research on coupling mechanism and feedback mechanism of grassland SES has evolved in terms of subjects,methods,and perspectives;human activities and climate change are the main drivers of grassland SES change;ecological restoration and rehabilitation,the establishment of protected areas,and enclosure for grazing prohibition are the primary measures for the conservation management of grassland SES.Innovation of socioeconomic systems plays a key role in grassland restoration.[Conclusion]In the context of increasingly complex human-environment relationships and global change uncertainties,future research should develop cross-scale and cross-regional comprehensive research theories;external policies should be incorporated into the components of grassland SES to better understand dynamic mechanisms;and future studies should also deepen the analysis of multi-factor interactions and policy applicability,optimizing management strategies to ensure the coordinated development of ecological,economic,and social benefits in pastoral regions.
