Helan Mountain is very suitable for rodents to survive because of its unique vertical distribution zone of plants. However, since the ecological restoration of the protected area, no research has been seen to evaluate the habitat suitability of rodents in Helan Mountain, making its distribution status unknown. Evaluation of species' habitat suitability is an important part of wildlife research. In recent years, more and more models and technologies including the continuous development of Geographic Information System (GIS) have been applied to the study of habitat suitability. We investigated six different species in the west slope of Helan Mountain in order to research the habitat suitability of the rodents by GIS and MAXENT model. The results showed that the main environmental factors that affected rodents were altitude, slope and distance from the mining area. Habitats with high altitude was not suitable for rodents to survive. We found that the largest overlapping area of suitable habitats of each was dedicated by Apodemus peninsulae and Spermophilus alashanicus (261.37 km²), and the smallest one was Allocricetulus eversmanni and Meriones meridianus (19.00 km²). The intersection area which was suitable for all six species was only 17.14 km², occupying 0.47% of the region of Helan Mountain; on the country, the unsuitable habitat that all six species was 2985.23 km² (accounting for 81.21% of the total area of Helan Mountain). According to the research, the distance from habitats to a mining area is still one of the most important environmental factors affecting the rodents' suitable habitats. It is recommended to continue to implement measures such as restricting mining areas and advocating residents around the reserve to promote the quality of rodents' habitats in the Helan Mountain.
