混播草地应对环境胁迫的耐受机制与生态修复能力
Tolerance Mechanisms and Ecological Restoration Capacity of Mixed-Sowing Grasslands in Response to Environmental Stresses
摘要
Abstract
Mixed-sowing grasslands,established by sowing two or more forage species in combination,are widely used in forage production and ecological restoration of degraded grassland.Compared to mono-cultures,multispecies mixtures markedly enhance the ecological functions and ecosystem stability of grass-land plant communities.However,the adaptive responses and underlying mechanisms of mixed-sowing grasslands under different environmental stresses remain insufficiently synthesized.Based on domestic and international research,this review explores how resource complementarity,interspecific competition,and species asynchrony mediate community function and stability in mixed-sowing grasslands.Three typical abiotic stress factors,such as drought,soil salinization,and heavy metal contamination,are used to exam-ine the community-scale adaptive responses of mixed-sowing grasslands and the ecological mechanisms underlying these responses.Practical approaches to remediating saline-alkali soils and heavy metal-contaminated sites are also summarized,with the aim of providing a theoretical reference for degraded grassland restoration and the efficient and sustainable use of grassland resources.关键词
