水涝胁迫下植物根系的生态韧性与互作机制研究进展OACHSSCD

Against the backdrop of global climate change and urbanization acceleration,urban waterfront areas,as the ecologically sensitive zones where terrestrial and aquatic systems intersect,are subject to frequent waterlogging stress.Their ecological resilience maintenance and their sustainable development have therefore emerged as critical issues to be urgently solved.This paper reviews the adaptive mechanisms of plant root systems and rhizosphere interaction patterns under waterlogging stress,with particular emphasis on the morphoplastic responses of roots,the adaptive modifications of root architecture(including geometric parameters,topological structure and growth rate),and the regulatory roles of rhizosphere microorganisms in shaping root architecture.Furthermore,it elucidates the ecological basis by which plants enhance community stability through mechanisms such as hydrological niche segregation and interspecific synergistic interactions along stress gradients,and explores the application potential of mixed planting of species with divergent root architectures in maintaining niche stability.The synthesis indicates that niche differentiation configurations based on plant functional traits,together with the reinforcement of interspecific collaborative adaptation relationships,constitute the core pathway for constructing highly resilient waterfront plant landscapes.By integrating theories of individual plant adaptation and community-level interactions,this review aims to provide a theoretical foundation and practical references for optimizing the ecological functions of waterfront plant landscapes,mitigating waterlogging-induced disasters,and facilitating sustainable management in the building of sponge cities.
