Ovis ammon darwini is one of a typical desert ungulates.In recent years, with the environment of wildlife habitat worsening and excessively human interference, the region of Ovis ammon darwini was continuing to reduce. Therefor, it had been extremely essential to protect Ovis ammon darwini populations and its habitat. Study of samples and control quadrants are still widely used ungulate wildlife habitat research. We studied different seasons habitat selectivities by Ovis ammon darwini in Mount Kalamaili Ungulate Nature Reserve(MKUNR), Xinjiang, China. We collected the ecological factors by via line transects methods from March in 2012 to February in 2015.1.The results showed that, in spring, Ovis ammon darwini preferred to select mountain slope with 30-60°, 900-1100 m of altitude, with distance less than 0.1km to hidden objects, with distance of 4.0-6.0km to permanent water source, with distance of 0.5-1.0km to the human communities, with distance of 0.5-2.0km to the main road and herbal density was above 3.0 plant?m-2, with high canopy cover about 0.9-1.0. In summer, Ovis ammon darwini preferred to select mountain slope, above 1300 m of altitude, with the distance less than 0.1km to hidden content, with distance more than 1.0km to human communities, with distance below 4.0km to water source, with herbal density above 3.0 plant?m-2, with vegetation coverage less than 0.1 and high canopy cover was 0.9-1.0. In winter, Ovis ammon darwini often preferred to select the area with the altitude of below 900 m, with the slope degree of 30-60°, with distance less than 0.05 km to hidden objects, with distance more than 4.0km to the water source, with distance of 0.5-1.0km to main road and human communities, with herbal density about 1.0-3.0 plant?m-2 and the canopy cover was 0.5-1.0.2.Results of Principal Component Analysis(PCA)showed that habitat selectivities of Ovis ammon darwiniwas mainly affected by artificial and natural factors, incuding altitude and human disturbance in spring, by plant species and water sources in summerand depending on food and the influence of human activities in winter.3. Chi-square and U test for different seasons of Ovis ammon darwini habitat utilization analysis and comparison showed that compared to the spring and summer, there be significant difference in slope, altitude, plant species, distance to hidden objects, distance to water source, distance to main road and human communities, otherwise, there was no difference in landforms. Compared to the spring and winter, there be significant difference in altitude, slope, distance to hidden object, distance to the main road and herbaceous density. Compared to the summer and winter, there be significant difference in landscape, slope, distance to human communitis, canopy cover and herbal density. In Mount Kalamaili Ungulate Nature Reserve, Ovis ammon darwinisurvie with seasons change, habitat selection activities will also be some difference, to maximize their own interests to make changes in habitat choice, which is the method to better adapt to the living environment in the region.
