Abstract Litter decomposition is a key ecological process as control on nutrient cycling in forest ecosystems. Forest litter an important carrier of element cycles The biogeochemical cycle elements great significance to plant communities and ecosystem functions. At present, most the studies major have focused only C, N, P, there are few sodium (Na) manganese (Mn) litter. In this study, we investigated concentrations fluxes Na Mn needle Qinghai spruce over 12‐month period. We measured release accumulation dynamics during at different canopy coverage elevations 3.9 years. results show that annual were 312.34 621.19 mg kg −1 , 236.67 343.16 g ha litter, respectively. After years decomposition, released 15.6% accumulated 93.4% compared initial concentration. concentration both fastest low coverage. various elevations, but was no obvious regularity. These illustrate seasonal characteristics return typical coniferous forests Qilian Mountains could provide basic data theoretical basis for protection Mountains.
