| Abstract: | Gansu Province is located in the northwest of China and the topography is complex. There grassland area and rich plant resources. The flora of grassland plants was studied according to the areog are vast raphy of the seed plants in China （WU Zheng-yi）,and the flora composition,plant families,genera and their distribution characteristics were analyzed. The results showed that the plant resources are abundant,there are 154 families, 706 genera and 2128 species,the dominant flora were temperate. The features of transition and interpenetration of floristic composition are significant. The flora is mainly composed by the young components with few Chinese endemic genera. |
