The paper aims to make full use of climate resources and rationally arrange the agricultural and animal husbandry production. Based on the meteorological data of 4 counties and stations in Huangnan Prefecture from 1961 to 2018, we estimated the climatic potential productivity of local natural grassland by Miami model and Tharnthwaite Memorial model, analyzed the main influencing factors and simulated the response of climatic potential productivity under different climate backgrounds. The results show that: Tongren with better water-heat coordination is the area with the greatest climate potential productivity in Huangnan Prefecture, the smallest climate potential productivity is in Zeku with the worst water-heat coordination, the climate potential productivity is mainly limited by temperature in southern Huangnan and precipitation in northern Huangnan. When the climate changes to warm and wet, it is advantageous to increase the climatic productivity of grassland in Huangnan; when the climate changes to cold and dry, it is extremely disadvantageous to increase the climatic productivity of grassland in Huangnan.
