Meta-analysis of effect of grazing intensity on soil microbial diversity and ecosystem multifunctionality of grassland ecosystems in Inner Mongolia
[Objective]To investigate the effects of grazing intensity on soil microbial diversity and individual ecosystem function indicators in Inner Mongolia grasslands,and to comprehensively assess the response of ecosystem multifunctionality(EMF)to grazing intensity.[Method]This study employed a Meta-analysis approach,integrat-ing data from 29 articles that examined the effects of grazing intensity on ecosystem multifunctionality in Inner Mon-golia.[Result]The findings indicate that bacterial diversity is more sensitive to grazing intensity compared to fungal diversity,with severe grazing significantly reducing the Shannon-Wiener index of bacteria.Moderate and heavy grazing significantly decrease the multifunctionality of grassland ecosystems in the Inner Mongolia region.Fungal di-versity plays a crucial role in regulating the multifunctionality of grassland ecosystems in Inner Mongolia.[Conclu-sion]It is recommended to implement light grazing in Inner Mongolia grasslands to promote the healthy and sustain-able development of grassland ecosystems.
