摘要: 近几年来,我们多次对西沙群岛珊瑚礁作了生态调查,对西沙群岛的岛、礁有了一定的认识,对造礁石珊瑚群落结构也进行了概括的报导[1],为了进一步认识和了解西沙群岛,我们又于1976年4—5月选择处于西沙群岛西南隅的沙岛——中建岛,和位于西沙群岛东北面绿树成林的赵树岛作重点解剖,对造礁石珊瑚群落结构做了进一步的分析,以期为发展和利用珊瑚礁做一点有用的工作。Abstract: A further ecological survey of the coral reefs of the Xisha Qundao has been carried out during April-May,1976.The quantitative and qualitative data given in this paper were obtained by direct underwater observations using aqualung and skin diver,and by analyzing the transect work with quadar.ts.Transects were placed from the shore to seaward slopes along the NE,SW,SE,NW directions of the reef respectively.A wooden quadrat of 1 m2 was laid down at random at intervals of 50 m along the transect,thus numbers of species and percentage covered in per quadrat could be recorded.Shannon-Weaver's index was used to specify the divesity of the hermatypic corals.
