Abstract

Abstract:

The relationship between biodiversity and ecosystem function （BEF） has always been a hot topic in ecosystem ecology. Climate change， especially the frequent occurrence of extreme precipitation events， is the main driving force to induce changes in ecosystem composition， structure and function. However， the differences of biodiversity and the regulatory mechanism of ecosystem multifunctionality in this process of have not been clearly understood. To explore the underlying mechanisms of how extreme drought influences biodiversity and ecosystem multifunctionality and their interactions in grassland ecosystems. This study systematically examines the impacts of extreme drought on plant diversity， soil biodiversity， and plant-soil multifunctionality in grassland ecosystem. It synthesizes and analyzes research findings concerning how climate change affects biodiversity， ecosystem multifunctionality， and their interrelationships across different ecosystems， community types， and spatial scales （global， regional， and local）. Key existing challenges in current research are critically evaluated. Finally， future research directions are proposed and discussed.

Key words: grassland ecosystem, biodiversity, ecosystem multifunctionality, extreme drought
