广西涠洲岛珊瑚分布状况研究
|
摘要
文章根据2017年涠洲岛最新珊瑚本底调查资料,对比分析近10年来,涠洲岛珊瑚种类数量、分布状态以及优势物种变化状况。结果表明,涠洲岛珊瑚以造礁珊瑚为主体,高达10科23属41种,其次为分布有较多的柳珊瑚,为4科12属14种,此外也分布有少量的软珊瑚、群体海葵;珊瑚主要分布于近海海岸一带,以0. 5～6 m的珊瑚礁坪生长带为主,具有明显的分带特点;对比2008年调查数据,本次调查发现涠洲岛海域珊瑚优势物种发生了变化,由角蜂巢珊瑚属变为滨珊瑚属,蔷薇珊瑚属不再是优势属,反而新增了蜂巢珊瑚属和牡丹珊瑚属,此外珊瑚覆盖度较2008年出现了下降趋势,表明了涠洲岛珊瑚生存状况受到了人为活动等因素的影响。
According to the latest coral diving survey data of Weizhou Island in 2017,the paper compared and analyzed the number,distribution and dominant species of coral species in Weizhou Island in the past ten years. The results showed that the corals of Weizhou Island mainly composed of reef-building corals,with 41 species belonging to 23 genera and 41 species,followed by more distributed gorgonians,14 species belonging to 4 families,12 genera,and a small number of soft corals and sea anemone; corals mainly distributed in the coastal area,with 0. 5 ～ 6 m coral reef flat growth belt as the main belt,with obvious zoning characteristics. Compared with the 2008 survey data,it was found that the dominant species of coral in Weizhou Island changed. From the horned coral to the genus coral,the rose coral was no longer a dominant genus,but had added the genus Hive and Peony,and the coral coverage had declined comparing to2008,indicating that the living conditions of corals in Weizhou Island was affected by factors such as human activities.
