%X With data from spots located water-level-fluctuation zone in Xiaojiang Small watershed during May, July and September in 2009, a research has been carried out the species composition, biomass and diversity of plant. The results showed that 140 species of vascular plant belong to 38 families, 113 generas. Herbs or xerophytes were main components. There were 18 species of the dominant species of plant communities, for example Cyperus rotundus, Xanthium sibiricum, Comnyza canadensis, Cynodon dactylon and so on. The plant biomass of fresh weight ranged 140.7 to 2055.6 g/m2 on an average of 999.9g/m2. The plant biomass of dry weight ranged 26.5 to 932.6 g/m2 on an average of 310.7 g/m2. The plant diversity indices such as Margalef index, Shannon-Wiener index, Simpson index and Pielou index in July were higher than those in September. The decrease order of plant diversity indices were 160 m, 170 m and 150 m from July to September. The succession trends and effect factors, restoration and utilization of plant were discussed in water-level-fluctuation zone.
