Abstract The biogeochemical processes of carbon (C), nitrogen (N), and phosphorous (P) are fully coupled in the Earth system, which shape the structure, functioning, and dynamics of terrestrial ecosystems. However, the representation of P cycle in te

Snow cover plays an important role in hydrological processes and seasonal water balance. Especially in the Tibetan Plateau (TP), snow cover is an important source of the Yangtze River, Yellow River and Lancang River (SRYYL), which greatly influences
