海平面变化重建结果是一个重要的气候变化指标,可以被用来与其他气候指示要素以及基于计算机模型的重建结果进行比较,从而可以更好地理解海平面变化以及与其气候系统其他要素之间的关系。从深海沉积物中的钙质有孔虫得到的氧同位素记录包含着全球大陆冰量的变化过程,因此可以用来重建地质历史时期海平面演化的历史。尽管诸多研究者利用海洋沉积物中有孔虫氧同位素比值作为基础数据重建了长时间尺度上连续的海平面变化记录,但是,在未来的海平面重建过程中,还需要与其他学科领域结合,并对海平面重建结果和其他气候指标进行对比和相互验证,才能获得可靠的海平面变化记录。
The result of sea level change reconstruction is an important indicator of climate change that can be used to compare with other indicators of climate indicators and reconstructions based on computer models to provide a better understanding of sea level changes and their relationship to other elements of the climate system relationship. Oxygen isotope records from calcareous foraminifera in deep-sea sediments contain changes in global ice mass and can therefore be used to reconstruct the history of sea level evolution during geological history. Although many researchers have used the foraminiferal oxygen isotope ratio of marine foraminifera as the basic data to reconstruct the continuous sea level change record on the long time scale, it is necessary to combine with other disciplines in the future sea level reconstruction, And to compare and verify sea level reconstruction results with other climate indicators in order to obtain reliable sea level change records.
