海南岛清澜港红树林群落演替系列的物种多样性特征

应用物种丰富度、Ｓｉｍｐｓｏｎ指数、Ｓｈａｎｎｏｎ－Ｗｉｅｎｅｒ指数、Ｐｉｅ种间相遇机率、ＭｃＩｎｔｏｓｈ指数和基于Ｓｉｍｐｓｏｎ的均匀度指数测度海南省清澜港红树林演替过程中群落物种多样性动态特征。结果表明。除均匀度指数变化规律不明显外，其它均表现出非常一致的动态趋势，即群落在演替初始阶段变化趋势均是由少增多，在中期阶段达到高峰后趋于下降，但在演替的后期阶段又有回升趋势。

The Characteristics of Species Diversity for the Successional Series of Mangrove Community in Qinglan Harbor of Hainan Island

Species abundance, Simpson index, Shannon|Wiener index, Pie species encountering ratio, McIntosh index and the evenness index based on Simpson index were used to analyze the dynamic characteristics of species diversity for community during the succession process of mangrove at Qinglan Harbor. The research indicated that most of the above indexes showed a considerable consistent dynamic tendency except the evenness index, i^e^ during the initial period of the community succession, the indexes increased gradually. During the medium period, indexes attained the maximum firstly, and then tended to decrease. During the last period,the indexes began to increase again. These characteristics could perfectly describe the dynamic changes of the mangrove community.
