Dynamics of Fine Root Decomposition in Different Vegetation Types: Investigating the Impact of Soil Fungal Communities and Enzyme Activities

Fine root decomposition plays a vital role in driving the carbon cycle terrestrial ecosystems, as it constitutes substantial part of annual net primary production and, transient tissues, returns to soil within relatively short timescales. Soil fungal communities and enzyme activities strongly influence this process. In study, we used an situ core method compare fine rates Liriodendron chinense (Hemsl.) Sargent, Cunninghamia lanceolata (Lamb.) Hook, Phyllostachys edulis (Carrière) J.Houz forests over 1-year period (March 2021–March 2022). We quantified chemical attributes roots enzymatic across different forests, detected via ITS rRNA gene sequencing, forecasted functional groups using FUNGuild database. The results showed that was fastest Sargent forest (77.2%) slowest for Hook (59.2%). Structural equation modeling (SEM) indicated content fungi are crucial decomposition. They not only directly but also promote through activities, clearly suggesting changes can be employed explain ecological effects This study illuminates significant differences characteristics roots, among types, all which significantly affect
