摘要:

2008年5-6月在徐闻西岸设置了25个站点, 运用截线样带法调查了造礁石珊瑚的种类多样性和空间分布。本次研究共发现造礁石珊瑚57种, 每个站位的种类数均不超过30种。Shannon-Wiener多样性指数和Pielou均匀度指数均值分别为1.79和0.42。二异角孔珊瑚(Goniopora duofasciata)、盾形陀螺珊瑚(Turbinaria peltata)和锯齿刺星珊瑚(Cyphastrea serailia)是优势种, 其中二异角孔珊瑚为绝对优势种。造礁石珊瑚覆盖率在0-38%之间, 大部分站位介于10-20%, 平均为12.1%。调查区珊瑚礁分布不规则, 呈斑块状分布。

Abstract:

We surveyed the community structure, species diversity and distribution of scleractinia coral off the shore of Xuwen County, Guangdong Province from May to June of 2008. A total of 57 species of scleractinia coral were documented from 25 sampling stations. Fewer than 30 species of coral were observed at any one station. The average Shannon-Wiener index of scleractinia coral diversity was 1.79 and the average Pielou index was 0.42. The dominant coral species within the study site were Goniopora duofasciataTurbinaria peltata and Cyphastrea serailia, particularly G.duofasciata. The average coverage of scleractinia coral was 12.1%, ranging in 0-38% (mostly in 10-20%). The scleractinia coral communities in our study site showed a patchy spatial distribution.
