Abstract

This study aims to assess the impacts of both climate change and anthropogenic disturbances such as mining development and urbanization on pasture grazing capacity and its vulnerability in arid and semi-arid regions. To achieve the purpose, we have developed an integrated model to evaluate the pasture grazing capacity (GC), grazing pressure (GP) and vulnerability (VI). The model was applied to four target areas: an urban area (Ulaanbaatar) and steppe area (Altanbulag) in semi-arid regions and a mining area (Khanbogd) and desert (Manlai) in arid regions. The results revealed that GP greatly exceeded GC in the urban and mining areas, where presented higher vulnerability than other areas. The order of GC, GP and VI was: (1) GC: steppe area > urban area > desert area > mining area, (2) GP: urban area > steppe area > mining area > desert area, and (3) VI: urban area > mining area > desert area > steppe area. Finally, the change rate of GC, GP and VI in last two decades implied that comparing with climate change; anthropogenic disturbances had more significant impacts on pasture vulnerability.
