Habitat Suitability and Overlap Analysis of Gazella subgutturosa and Equus hemionus in Summer in Mt.Kalamali Ungulate Nature Reserve,Xinjiang
Distribution status of different main species in the same area should be considered in the conservation of a par-ticular species.Mt.Kalamali Ungulate Nature Reserve in Xinjiang is the area with the most concentrated distribution of Gazella subgutturosa and Equus hemionus,and with the largest number of E.hemionus.There are few human activities in this area,which is suitable for habitat overlap research.Based on the transect survey data in the summer of 2022,the Max-Ent model was used to obtain the suitable habitats of the two species,and the overlap of the suitable habitats was calculated.The results showed that:(1)the suitable habitat areas of these two species were 3 934 km2 and 4 036 km2,accounting for 26.85％and 27.54％of the total area,respectively.(2)The environmental factors that had the greatest influence on the habitats of these two species were the distances from railway and water source,and the average temperature of the wettest season.(3)Niche overlap index D and I values were 0.827 9 and 0.971,respectively,indicating that the spatial niches of these two species were highly overlapping.The overlap area of suitable habitat for both species was 2 479 km2,account-ing for 63.01％and 61.42％of the suitable habitat area,respectively.It is suggested that the main protection areas in the study area should be planned according to the overlapping suitable habitat and water source distribution of the two species,and corridors should be established to reduce the impact of railway on the species.Therefore,the result of this study can provide reference for the regional planning and protection of Kalamari National Park.
