摘要/Abstract

摘要： 涠洲岛位于南海珊瑚礁分布的北缘.温度是影响其珊瑚礁生态系统发育的重要因素.对器测温度分析发现,近42年来涠洲岛海面温度(SST)与全球气候变暖呈准同步变化趋势,存在3～4年与7～8年的变化周期,20世纪80年代后期以来,涠洲岛SST上升比较明显.其月平均最高SST的持续上升将使本区珊瑚生长处于一种非常敏感的边缘,加上人类活动(建筑取材、炼油、旅游、捕鱼、养殖等)对涠洲岛珊瑚礁的潜在不利影响,则可能导致珊瑚礁的退化.此外,在系统的野外调查基础上,描述了涠洲岛现代珊瑚礁的分布范围.

Abstract: Weizhou Island (109°00'～109°15'E,21°00'～21°10'N) locates in the north coral reef distribution belt of the South China Sea.In such relatively high latitude area,sea surface temperature (SST) is an important factor affecting the development of coral reef ecosystem.Measurements of the latest 42 years' SST of Weizhou Island showed that with 3～4 years and 7～8 years fluctuating cycles,the SST almost had a synchronous increase with global warming,especially since the later 1980s.Overall,the coral reef of Weizhou Island could benefit from the SST warming,especially the cold months SST increase,because it's the north margin of tropical zone.But,the warming of the warmest month may be a thermal stress on the development of coral reef.It reaches the upper limits of coral reef development,and leads the coral reef bleaching.Mankind activities,including wide scale building,oil gas factory near the island,traveling,fishing and breeding,may be also the potential stresses on limiting the coral reef development.The combination of summer warming and mankind stress is possibly to destroy the coral reef ecosystem of Weizhou Island.Based on a detailed field investigation,the modern coral reef distribution map around Weizhou Island was described.
