Human activities have been a main cause of floral and faunal species extinction and loss of local and global biodiversity. Habitat and population can become fragmented and isolated under anthropogenic disturbances. In this study, we focus on the effect of human activities on the habitat and population of the giant panda (Ailuropoda melanoleuca) in the north slopes of Daxiangling Mountains, Sichuan province, China. Based on eight months of field investigation in 2004, we found that the distribution of the giant panda population has been limited to remnants of habitat due to human activities such as road construction, mining and hydropower stations. There is 100.60 km2 area suitable for the giant panda (including moderately suitable, suitable and most suitable), which only accounts for 21.33% of the bamboo area. Based on a dispersal model COST, there were 79.94 km2 areas (17.12%) (including moderately suitable, suitable and most suitable) for giant panda utilization in reality. Only 16.35 km2 areas (3.5%) of total bamboo area were most suitable. The areas that suitable for panda had decreased 20.66 km2 from 2000 in total due to people activities. The results of this study can be used to provide basic information to build nature reserve for protecting giant panda in Daxiangling Mountains.
