Abstract: The population densities(using pellet-count method) of alpine musk deer(Moschus chrysogaster) in the three fragmented isolated forests in the Shoulu Mountain Nature Reserve were compared:the density in Mt. Laohu Forest being 10.20～71.11 ind/km2,in Mt. Changling Forest 17.93 ind/km2,and in Mt. Shoulu Forest 3.90～18.36 ind/km2.The comparison showed that the densities in arbor forest and shrub are great;high and continuous dense shrub was disadvantageous to the musk deer,and patchy shrub was beneficial to them.Thus,the environmental factors conditioning the population densities and distribution of the musk deer was analyzed,and some conservative strategies were put forward.

Key words: Moschus chrysogaster, small isolated population, current situation, population conservation, Shoulu Mountain Nature Reserve
