Abstract: Alashan desert area is one of the 8 biodiversity protection centers in China, which is passed by the expressway from Inner Mongolia to Xinjiang. The passages for ungulate species have been designed along the highway during the construction. It is of great importance to evaluate the suitability of animal passages for the ungulates. Based on the niche theory, we used fuzzy comprehensive evaluation method combined with GIS spatial data presentation to evaluate the habitat suitability of ungulate species along the highway in this study. The results show that the suitability index of animal passages declines along the highway from east to west. In the section K46-K168, the suitability index changes greatly, the change of suitability index is the second among the sections of K295-K620, and the change of suitability index is smaller between the sections of K641-K891. The distance between the drinking water, the distance from the residential area and the number of drinking water points are the main causes of such changes. There is a significant difference in suitability index from the highway. Except for the influence of highway elements on suitability, other factors and their superimposed effects on the suitability index are not significant.
