Abstract: In this study, the relevant information about Trgopan temminckii collected by infrared camera survey in Wolong National Nature Reserve from 2014 to 2019 was collected, and species distribution model (MaxEnt) was used to predict the suitable habitat of Trgopan temminckii in the Nature Reserve. The difference of activity rhythm in spring, summer, autumn and winter was analyzed using kernel density estimation method. The results showed that in Wolong National Nature Reserve, the predicted suitable habitat for Trgopan temminckii was 430.38 km², accounting for 21.52% of the total area of the reserve, which was mainly distributed in the coniferous and broad-leaved mixed forest at middle and low altitude on both sides of Pitiao River in the reserve. In terms of activity rhythm, the highest activity intensity of Trgopan temminckii was in spring followed by autumn and summer, and the lowest in winter. The daily activity rhythm of Trgopan temminckii in autumn was significantly different from that in spring, summer and winter, but there was no significant difference between spring, summer and winter. This study preliminarily identified the potential suitable habitat distribution of Trgopan temminckii in Wolong National Nature Reserve and the difference of activity rhythm in spring, summer, autumn and winter, which provided scientific basis for the conservation and management of Trgopan temminckii and other Phasianidaes distributed in the same area in the reserve.
