摘要：以杭州湾不同年份形成的滩涂湿地植被群落为研究对象,采用样线法结合样方法进行调查取样,并通过除趋势对应分析排序研究了群落演替的动态和方向,同时采用Pielou均匀度指数、Margalef丰富度指数、Shannon-Wiener多样性指数和Simpson多样性指数分析了物种多样性在群落演替过程中的动态变化。结果表明:该区域植被群落演替序列为海三棱藨草群落→芦苇群落→柽柳+芦苇群落→旱柳+白茅群落;随着演替的进行,群落物种丰富度显著增加,均匀度逐渐降低,物种多样性呈先增加后降低的趋势。
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 sion series of vegetation communities in test area succession. The results showed that the succes- was Scirpus mariqueter→Phragmites communis→ Tamarix chinensis ＋ Phragmites communis→Salix matsudan ＋ Imperata cylindrica. With the suc- cession progressed, the species richness increased significantly, evenness decreased, while species diversity increased first and decreased then.
