Abstract: In order to explore the ecological factors affecting the growth of Astragalu smembranaceus var. mongholicus, we investigated the resource distribution, habitat characteristics and growth conditions of wild and cultivated A. membranaceus var. mongholicus by fixed-plot observation, survey method, and literature. These data were analyzed by traditional Chinese medicine GIS-Ⅱ (TCMGS-Ⅱ) to obtain the most suitable areas of A. membranaceus var. mongholicus within Inner Mongolia. The results showed that the production areas of cultivated A. membranaceus var. mongholicus were mainly located in Wuchuan County, Guyang County and other 15 counties, which were cha-racterized by the altitude higher than 1000 m, with soil type of sand, gravel and calcareous clay. The wild A. membranaceus var. mongholicus was distributed mainly in the eastern Inner Mongolia and germinated in sunny place, which preferred to the cold dry climate and sandy loam soil or gra-vel but avoided damp heavy clay soils. There are 43 counties of 94460.30 km2 for wild A. membranaceus var. mongholicus, and 32 counties of 76013.93 km2 for cultivated one within Inner Mongolia, with a similarity coefficient of ecological factors greater than 95%.
