摘要
造礁珊瑚骨骼δ^(13)C是记录环境变化的重要参数之一,本文总结了其研究概况:(1)光合作用及与之相关的环境参数如日照、云量等是影响珊瑚骨骼δ^(13)C的主要因素;(2)珊瑚骨骼δ^(13)C能揭示日照时数、ENSO等环境信息;(3)珊瑚骨骼δ^(13)C与δ^(18)O有正相关、负相关和无相关3种情况,可以解释相应的环境状况.
The reef coral skeleton's δ13C is one of the significant indices in monitoring environmental changes. This paper summarizes the general study situation in the following three aspects: (1) The photosynthesis by the endosymbiotic algae, as well as the related environmental factors such as light intensity, cloud cover et al. , is a dominant factor influencing coral δ13C. (2) Coral skeleton δ13C can be used to reconstruct the past light intensity, ENSO events and other related environmental factors. (3) The relationship between coral skeletons δ13C and δ18O , including positive correlation, inverse correlation and non-correlation, can be used to explain the environmental condition.
