Abstract Plant diversity loss caused by climate change decreases soil organic carbon (SOC) sequestration, but the mechanism involved remains unclear. Investigating changes in microbial necromass (MNC) accumulation along a climate–plant species gradient can help clarify this mechanism, as it is crucial for stability of SOC. We conducted large‐scale sampling across 2500‐km transect through grasslands on Tibetan Plateau to investigate MNC content and its contribution SOC at depths 0–20 20–40 cm response environmental plant gradients. richness, biomass, proportion above‐ground biomass accounted Cyperaceae (sedges) increased with decreasing aridity rising altitude. Meanwhile, content, SOC, ratio fungal bacterial both layers also aridity. These results indicate that, addition changing factors altitudinal gradient, richness plays pivotal role facilitating thus accrual Structural equation modelling revealed that increases enhancing abundance grassland. A higher significantly root level rhizodeposition, thereby increasing activity microbes, ultimately MNC. Synthesis . conclude dominate Plateau. findings demonstrate importance incorporating into conservation efforts mitigate negative impacts human activities
