Abstract: By using line transect method, the distribution patterns of giant pand
a population and its sympatric companion wildlife species in Foping and Guanyins
han nature reserves were investigated in October 2007 and April 2008, and the en
vironmental factors affecting the spatial distribution of giant panda activity w
ere analyzed. The giant panda population and its sympatric companion wildlife sp
ecies in the two reserves had the similar distribution patterns, and the density
 and distribution range of giant panda were smaller in Guanyinshan than in Fopin
g. Giant panda had two high-density distribution areas in Foping, but no activi
ty trace in most parts of Guanyinshan. The activity trace of Budorcas taxicolo
r, Naemorhedus goral and Sus scrofa was more in Guanyinshan than in Foping
. Anthropogenic interference might affect the distribution pattern of giant pand
a.
