摘要：Line transect and plot sampling methods were applied to investigate the vegetation communities developed in different years in beach wetlands of Hangzhou Bay. DCA (detrended correspondence analysis) ordination technique was used to clarify the dynamics and direction of vegetation community succession, and the Pielou' s evenness index, Margalef' s richness index, Shannon-Wiener diversity index, and Simpson' s diversity index were introduced to analyze the dynamics of species diversity during community succession. The results showed that the succession series of vegetation communities in test area was Scirpus mariqueter → Phragmites communis → Tamarix chinensis + Phragmites communis → Salix matsudan + Imperata cylindrica. With the succession progressed, the species richness increased significantly, evenness decreased, while species diversity increased first and decreased then.
