Influences of longterm water stress on diversity characteristics of typical wetland plant communities

Abstract

Abstract: Studies on vegetation diversity under different water gradients were conducted for wetland conservation and restoration. Based on 2005-2007 year simulation test, diversity dynamics of typical wet meadow （Calamagrostis angustifolia community）, swamp meadow （C. angustifolia-Carex lasiocarpa community） and marsh communities (C. lasiocarpa community) under various water conditions were analyzed in the Sanjiang Plain. The Shannon-Wiener diversity index and species richness of the three communities generally decreased while the Pielou’s evenness increased with the increasing of water level, and the species richness was found to be the most sensitive index; diversity indexes of swamp meadow and marsh communities were more sensitive to water gradients than that of wet meadow community; the community composition and structure were mostly affected by water stress at the beginning, but they were ultimately determined by various environmental and biological factors together.
