[Habitat selection attributes of giant panda].

Based on the 1997-2009 inventory data of Wanglang Nature Reserve, the habitat selection attributes of giant panda were studied from the aspects of topography, forest community structure, and main feeding bamboo by the methods of frequency distribution and Bailey. The giant panda had obvious habitat preferences. Topographically, the preferred microhabitat was on the even or convex slopes at the ridge, top, or middle part of mountain body at an elevation 2500-3000 m, with southwest aspect, 6 degrees-30 degrees, and the distance to the nearest water source > 300 m. As for the forest community structure, the giant panda preferred the microhabitat with the bamboo succeeded from secondary forest or mixed conifer and broad-leaved forest, and with the average tree height being 20-29 m and the shrub coverage being 0-24%. The preferred main feeding bamboo by the giant panda was the growing well Fargesia denudate with an average height of 2-5 m and the coverage of > 50%.
