| Abstract: | Natural grassland vegetations in the Loess Plateau lying in eastern Gansu Province can fall into two vegetation areas,meadow steppe and typical steppe regions and include 14 formations and 3 vegetation types. The three vegetation types are temperate hassock with sparsely distributed shrubs, meadow steppe and typical steppe and the fourteen formations are Ass. Ziziphus jujuba var. spinosa-Periploca sepium- Artemisia spp.hassock,Ass.
