Abstract:Habitat prediction is the basis for protection of wild animal. This paper taked Sichuan Xiaozhaizigou National Nature Reserve as the study region, applying the Maximum Entropy (MaxEnt) model to wild giant panda’s olfactory communication locations habitat suitability evaluation. A total of 33 sites were investigated in the March and October of 2016. A predictive habitat distribution map of giant pandas olfactory communication sites was estimated using with these recorded points and proper environment variables of giant panda's living condition, such as topographic data, human disturbance data. The cumulative contribution rate of Bamboo distribution (56.9%) and Ridge distance (29.9%) are 86.8%, which are the major ecological factors that affect the chemical communication of giant panda in this region. Olfactory communication locations were located primarily along bamboo forest and ridges. The habitat was divided into 2 classes including suitable and unsuitable habitat using 0.0615 threshold. The suitable habitat area is 15 187.50 hm2, which accounted for 34.22% of the area of the study area, mainly distributed in middle, the north and south contact with area other protected areas, and the unsuitable habitat area was 29197.20hm2, which accounted for 65.78%. In the case of limited manpower and material resources, this study provides data support for the reasonable allocation of protection actions of study area to strength protect of giant panda.
