造礁石珊瑚记录现代海洋生态环境信息研究进展

造礁石珊瑚因其独特的生物学和生态学特性,已被广泛用作环境因子的代用指标.过去国内外的研究主要侧重于地质年代环境信息的记录,随着样品分析测试精度的提高,用造礁石珊瑚骨骼研究现代热带的生态环境也逐渐增多,尤其对于影响海洋生态环境的事件信息的记录.许多研究都证明了造礁石珊瑚骨骼中各种示踪剂在监测过去环境变化方面的有效性,对目前和将来的生态监控以及环境研究都具有广阔的前景.目前,珊瑚基础生理学的机制尚未完全探明,进一步了解珊瑚微观结构层次的生理机制是该领域研究的关键所在.我国学者已开展了南海西沙、南沙、台湾岛、海南岛、徐闻和涠洲岛等地区的造礁石珊瑚骨骼多种指标的研究.

Modern marine entironment information records in hermatypic coral

Hermatypic coral has been widely used as proxy of environment factors because of its biological and ecological characteristics.Studies were focused on the paleoclimatic environment information records in the past.With the improved of sample analyse precision,coral skelecton has been more and more used in studies of modern tropical environment information,particularly in records of events which have given great impact on ocean environment.Results have proved that many trace elements in coral skelecton are good indicators in monitoring environment change and will be widely used in environment monitoring and studies in the future.At present,mechanism of coral physiology has not been completely proved up,more unfound details in coral micromechanism are the key of this field.In China,the study of multiform proxies of coral skelecton has been carry on,especially in Xisha Islands,Nansha Islands,Taiwan,Hainan, Xuwen and Weizhou Island.
