%X This paper studied the spermatophyte flora in the Hunshandake sand of central Inner Mongolia agriculture-animal husbandry ecotone,and compared it with the flora in whole Inner Mongolia.The results showed that there were 1191 species of spermatophyte in the sand,belonging to 402 genera and 84 families.The geographic element of the flora was of multiplicity,and predominant with temperate floristic element,among which,North Temperate distribution elements had a higher percentage,and Compositae and Gramineae had the greatest proportion.The temperate floristic element had a trend of laying in big families,indicating that the plant distribution of Hunshandake sand had adapted to the climate of this area.The dominant families of the spermatophyte belonged to different elements,but most of them were the worldwide element.The original of the element was very ancient,and the geographic element was complex and transitive.In addition,the plant flora was significantly vulnerable.
