| Abstract: | Heihe River reaches is the greatest inner-continent basin of Hexi corridor in Gansu According to the preliminary investigation,there are 396 species,220 genera,55 families of seed plants in the basin,The primary characteristics of the seed plant flora are:the obvious temperate region feature,wide-ranging connection in the geographical elements with the near floristic areas and fewer species originated in the old.Mediterranean area.On the basis of the distribution of endemic species and some physiographical features,the flora of middle-lower reaches of Heihe River belongs to the one of Alashan sub-region of Asian desert flora. \ \ |
