Abstract: The giant panda of the Xiaoxiangling Mountains are distributed in Shimian, Mianninng and Jiulong Counties. Their population size is one of the lowest among all mountain regions. The results of the 3rd Nationwide Giant Panda Census show that the total area of giant panda habitat in this region 802.04 km²，the population size of the giant panda is 32 individuals. There is panda habitats of 489.68 km² and 24 individuals in three Nature Reserves located in the Xiaoxiangling Mountains. Area of the panda habitats is 168.01km² and there are 6 individuals at the Sichuan Yele Nature Reserve of Mianning County. Area of the panda habitats is 306.38 km² and there 14 individuals at the Sichuan Liziping Nature Reserve of Shimian County. Area of the panda habitats is 15.19 km² and 1individual at the Sichuan Gonggashan Nature Reserve. The panda habitats inthe Xiaoxiangling Mountains are seriously fragmented. The giant panda population in the Xiaoxiangling Mountains has been separated into two parts by No. 108 National Highway from Chengdu to Kumning, and includes individuals from two other isolated insular areas, so that it is a metapopulation of the giant panda. The size of subpopulation A, located to the east of No. 108 National highway, is 13 with relatively intact habitats of 263.54 km². The size, of subpopulation B, located to the west of No. 108 National Highway, is 19 with fragment habitat of 538.50 km². Because of small population size and fragmentation of habitat in the Xiaoxiangling Mountains,
the giant panda population is severely endangered. So conservation of the panda population and their habitats in the Xiaoxiangling Mountains must be enhanced.
