摘要:

根据石珊瑚物种的总数、石珊瑚覆盖的百分率、物种多样性和均匀度,对鹿回头岸礁造礁石珊瑚群落结构类型所处在演替阶段的时间状态和生境的空间状态进行分析。在中等和深水区物种多样性的时间变异,随演替的发展而有所下降;浅水区不随演替而变化。在不同生境区珊瑚生长的聚群上,与时间的发展无关;每个演替时期,物种多样性的类型与生境的变化有关。

AbstractPatterns of community structure , in terms of total number of species , percentage of coral cover , species diversity and evenness , of the hermatypic corals on Luhuitou fringing reef were analyzed on the temporal scale of successional phases and the spatial scales of habitats. Temporal variation of species diversity in the mid and the deep-zone declined during succession , while the shallow zone did not . There is no indication that coral assemblages in different habitats become more similar over time as corals grow ; each successional period showed significant between-habitat variability in the pattern of species diversity.
