Abstract: Based on the line transect surveys conducted from May 2023 to July 2024, this study evaluated the potential impacts of climate change on the suitable habitat of the Tibetan gazelle(Procapra picticaudata) in Shiqu County. The analysis identified slope direction, seasonal temperature variation, dailytemperature range and annual temperature range as the four primary environmental factors influencing gazelle distribution. The results showed that:the area ofexistingsuitable habitat was 2113 km², with an additional 9996 km² classified as sub-suitable. Of this, 771 km² of suitable habitat and 2342 km² of sub-suitable habitat lay within the Changshagongma Nature Reserve, with the remainder located outside the reserve. Excluding periods with small impacts, the suitable habitat for the Tibetan gazelle wouldbe only 50.84% to 73.17% ofthe existing suitable habitat under the four future climate scenarios(SSP126, SSP245, SSP375, and SSP585). Most of this suitable habitat would be shifted to higher altitudes in the northwestern and southwestern regions of the county, while the sub-suitable habitat would be 95.99% to 115.45% of its current extent. The findings indicate that future climate change would likely reduce high-quality habitats for the Tibetan gazelle, driving them to higher altitudes. Therefore, conservation efforts in Shiqu County should also focus on the western high-altitude mountainous areas.
