Abstract: Race samples and control quadrants were used to study habitat selectivity and seasonal variations of wolves in Mt. Kalamaili Ungulate Nature Reserve (MKUNR) of southeastern Junggar Basin,Xinjiang. The results showed that,in spring, wolves preferred to select mountain slope and mountaintop, 900-1 000 m of altitude, with distance of 2 to 4 km to permanent water source, 0.5-1 km to main road, 2-4 km to human community, and the canopy cover was 0.9-1. In summer, wolves preferred to select mountain slope and mountain trench, 900-1 000 m of altitude, with distance less than 2 km to permanent water source, 1.5-3 km to main road, 2-4 km to human community, and the canopy cover was 0.9-1. In winter, wolves preferred to select mountain slope and sand dune, under 800 m of altitude, with distance less than 2 km to permanent water source, 1.5-3 km to main road, 2-4 km to human community, and the canopy cover was 0.5-0.9. Principal component analysis (PCA) showed that habitat selectivity of wolves was mainly affected by human disturbance in spring, by water source in summer, and by food in winter.
