Abstract:Habitat prediction is the basis for the protection of wild animal. In this study, Maximum Entropy Modeling was applied to the wild giant panda's olfactory communication locations habitat suitability evaluation in Xiaozhaizigou National Nature Reserve, Sichuan. A total of 33 sites were investigated in March and October, 2016. A predictive habitat distribution map of giant pandas olfactory communication sites was estimated using these recorded points and proper environment variables of giant panda's living condition, such as topographic data and human disturbance data. The cumulative contribution rates of bamboo distribution (56.90%) and ridge distance (29.90%) are 86.80%, which are the major ecological factors that affect the chemical communication of giant panda in this region. Olfactory communication locations are primarily located along the bamboo forest and ridges. The habitat is divided into 2 classes including the suitable and unsuitable habitat using a threshold of 0.061 5. The suitable habitat area is 15 187.50 hm2, which accounted for 34.22% of the studied area and mainly distributed in the middle, north and south border adjacent to other nature reserves. The unsuitable habitat area is29 197.20 hm2, which accounted for 65.78% of the studied area. In the case of limited manpower and material resources, this study provides a basis for the reasonable allocation of protective actions for the conservation area to strength the protection of giant panda.
