| Abstract: | Based on the research and analysis of vascular plants in Worihe drought valley in Xiaojin county,its floristic characteristics are as follows:there are 262 species in vascular plants,which belong to 163 genera and 73 families,thereinto seed plants are dominant.To introduce the system of "The vegetation in Sichuan",we can divide it into 4 vegetation forms,4 formation classes and 11 formations.It is not rich in floristics and simple in flora components.The seed plant flora is characteristic of temperate zone and simple vegetation embodies obvious features of drought valley. |
