[Distribution patterns of giant panda in Guanyinshan and Foping nature reserves].

By using line transect method, the distribution patterns of giant panda population and its sympatric companion wildlife species in Foping and Guanyinshan nature reserves were investigated in October 2007 and April 2008, and the environmental factors affecting the spatial distribution of giant panda activity were analyzed. The giant panda population and its sympatric companion wildlife species in the two reserves had the similar distribution patterns, and the density and distribution range of giant panda were smaller in Guanyinshan than in Foping. Giant panda had two high-density distribution areas in Foping, but no activity trace in most parts of Guanyinshan. The activity trace of Budorcas taxicolor, Naemorhedus goral and Sus scrofa was more in Guanyinshan than in Foping. Anthropogenic interference might affect the distribution pattern of giant panda.
