Abstract:

From Jun.2001 to May 2002, vegetations in logged and un-logged area, include those used and not used area by Giant Panda, were systematically sampled and studied at Wanglang National Nature Reserve and Huangyang Giant Panda Monitoring Station, Pingwu County, Sichuan, China. The results showed that, at un_logged areas, number of species, the average of species richness, species frequent, bamboo generation ability, bamboo density and maximum DBH at the area used by Giant Panda were higher than that of unused areas. Comparatively, at logged areas, the average of species richness, species dominant, diversity, bamboo biomass, bamboo density, bamboo canopy density, average DBH and maximum DBH at the areas used by Giant Panda were higher than that of unused area. Logging in the Giant Panda habitat caused the decline of species richness, species dominant, diversity, bamboo density, bamboo canopy density, and had an influence on the Giant Panda's adaptability and the quality of its habitat.

Key words: logging, Giant Panda, habitation, Pingwu County
