Studies of species habitat and distribution patterns are an important prerequisite for conservation efforts, and habitat quality and integrity play a crucial role in the population health and recovery of endangered species. This is especially applicable to the snow leopard, a top predator that is key to highland mountain ecosystems. In this study, 112 valid snow leopard distribution loci obtained by infrared camera surveys in the mid-eastern Tianshan, Xinjiang were examined. Combined with 12 characteristic environmental variables, the maximum entropy model (MaxEnt) and GIS techniques were used to analyse the potential distribution areas and suitable habitats of snow leopards in the mid-eastern Tianshan. The results showed that the total area of suitable habitat for snow leopards in the mid-eastern Tianshan was 15919 km2, and the most suitable habitat was mainly concentrated in a western patch around Wusu, Hutubi, and the southern mountains of Urumqi. The results of a Jackknife analysis showed that land cover type, the daily difference in average temperature, isothermality, slope, and altitude were important factors affecting the distribution of snow leopards. Deciduous coniferous forests, grasslands, and bare rock areas with sparse vegetation at altitudes from 2500 m to 5000 m are the areas where snow leopards have a higher probability of occurrence in the mid-eastern Tianshan. This study determined the key distribution areas of snow leopards and provides a scientific basis for establishing key areas for snow leopard monitoring and protection in the mid-eastern Tianshan.
