Responses of CO2, CH4 and N2O fluxes to livestock exclosure in an alpine steppe on the Tibetan Plateau, China

摘要

Most alpine steppe grasslands on the Tibetan Plateau have in recent decades come under increasing threat from overgrazing due to population growth and food demand. Livestock exclosure has been widely employed by China’s state and local authorities as a management practice aimed at restoring and protecting these fragile ecosystems. However, its effects on greenhouse gas fluxes are unclear.
