Abstract:

There are thirteen kinds of hoofed animals in Inner Mongolia Plateau,including of four families,ten genes and thirteen species.Roe deer and red deer habitate in the ecotone between grassland and forest,the Tibetan gazelle,blue sheep,argrali sheep and aipinelbex dwell in the mountains and hills of the plateau.However,mongolian gazelle,przewalskis gazelle,goiterd gazelle,tibetan gazelle,mongolian saiga,mongolian ass,mongolian horse and wild camel are the typical hoofed animals in Mongolian Plateau.It has been a giant change for the kinds and numbers of hoofed animals in the Mongolian Plateau since modern times.przewalskis gazelle,goiterd gazelle,tibetan gazelle,mongolian saiga,and mongolian horse have disappeared from Mongolian Plateau,the other hoofed animals population has gone down quikly.The main reasons for the hoofed animals population decline is that the people disturbance,such as reclaiming and cultivating grassland,fencing forage,overuse of water resources,etc.Thus,to protect the hoofed animals in Mongolian Plateau,we should set up a national park system and ecological space for the hoofed animals.

Key words: Inner Mongolian Plateau, hoofed animals, population, habitat, transition
