Abstract: Green Peafowl (Pavo muticus) is inscribed in the Chinese First-Class National Protected Animals list for its rarity and preciousness. Anthropogenic habitat fragmentation threatens its survival. Based on 15 occurrence records of Green Peafowl and eight environmental parameters in Konglong River nature reserve of Yunnan Province in southwestern China, we evaluated the habitat suitability using MaxEnt Model and designed habitat corridors using Minimum Cost Model. The results showed that the area under ROC curve (AUC) of MaxEnt Model was 0.951, indicating an excellent assessment result of the model. The distance to river bank and the elevation were dominant environmental variables for the suitability of Green Peafowl habitats, with a contribution rate of 59.2% and 30.1%, respectively. The habitats with very high (44.47 km²) and high (76.91 km²) suitability were elongated and fragmented on both sides of the Konglong River, which together accounted for 15% of the total area of the nature reserve. Furthermore, 28 habitat corridors with a width of 1000 m were designed in the river valley between the elevation of 500-1000 m a.s.l., of which the total length is 232.08 km and the area is 241.97 km². Our results provided a scientific basis for the protection of Green Peafowl in China.
