草地生物多样性与生态系统功能研究进展
Research Progress in Grassland Biodiversity and Ecosystem Function
摘要
Abstract
Grassland ecosystems,as one of the most widely distributed terrestrial ecosystems globally,play an irreplaceable role in maintaining ecological balance and providing ecosystem services.Biodiversity,as their core attribute,exhibits a close and complex relationship with ecosystem functioning.The dynamic changes between the two directly influence the stability and service provision capacity of grassland ecosystems.This paper reviews the research progress at home and abroad in the relationship between biodiversity and ecosystem functions in grasslands,and specifically elucidates the interaction mechanisms among grassland biodiversity and productivity,stability,nutrient cycling,and soil microbial communities.From the perspectives of species complementarity effects and functional traits,the paper analyzes the pathways through which biodiversity enhances productivity.Based on the theories of asynchrony and complementarity,and reveals the mechanisms of biodiversity to maintain stability.By leveraging differences in species functional traits,it clarified the regulatory role of biodiversity on nutrient cycling efficiency,and simultaneously explores the critical role of plant-microbe interactions in driving the biodiversity-ecosystem functioning relationship.On this basis,based on environmental heterogeneity,species functional characteristics,ecosystem type and interference factors,the key factors affecting the above relationship are analyzed,and research prospects are discussed to provide a scientific basis for the protection,management and sustainable utilization of grassland ecosystems.关键词
