Abstract

Taking the vegetation at the water-level-fluctuation zone(WLFZ) of Xiangxi River as the object of the research, we use the sampling method to study the composition of species, diversity of community and dynamic pattern in two years at different altitudes after the filling of the Three Gorges Dam Reservoir. The results showed that species richness presented a trend which increased with the increase of the altitude. The main plants are annual herbs, an average of 26 species, accounting for 66.2%.Next were perennial herbaceous plants. Plants which belonged to gramineae and compositae form a community of absolute advantage in this area. In general, plant are patchinesses or banded concentration distribution. With the elevation increasing, and diversity increased. And the whole kinds of species would tend to be stable gradually in the WLFZ of Xiangxi River.
