Abstract:Based on available distribution information of Great gerbil (Rhombomys opimus) and vegetation cover maps (1:4 000 000 and 1:1 000 000) of China, GIS was applied to the systemic study of the distribution of the Great gerbil. According to distribution patterns of Haloxylon and Kalidium, the Great gerbil's habitats were divided into nine types, namely Haloxylon desert, Kalidium saline desert, Haloxylon ammodendron and Reaumuria soongarica loamy desert, Haloxylon gravelly desert, Calligonum desert, Tamarix scrub on arid saline meadow soil, spare Tamarix desert, Reaumuria soongarica gravelly desert, halophytic grass and forb meadow. The former four with Haloxylon and Kalidium as dominant plants were most suitable habitats. A distribution map of habitats of the animal by counties linked its habitats to vegetation types in vegetation cover map of China on a scale of 1:4 000 000 Depending on the localities of specimen collections and the habitats by counties, suitable habitats of the Great gerbil were identified. By assessing the habitat suitability, we studied the map of distribution patterns. Compared with the GIS model of species distributions in this paper, the distribution ranges in scientific literatures were larger than the actual ones. Some distribution localities verified against the species occurrence records were given in this paper. Based on the atlas of grassland resources of China on a scale of 1:1 000 000, we determined more reliable distribution limits of the Great gerbil. Results showed that distribution of Great gerbil has been changed by human activities.
