中文摘要: 海平面变化是全球变化的重要组成部分,不仅涉及自然环境和生态的变化,而且对人类社会的经济和发展也有重大影响。只有了解海平面变化历史,发现和掌握海平面变化规律,才能建立可靠的海平面变化模型,提高未来海平面变化的预能力。巽他陆架地处太平洋和印度洋的交界,位居世界陆架面积第二,陆架宽,坡缓水浅,对海平面变化敏感,是研究海平面变化的理想之所。简要介绍了海平面重建的方法,回顾了巽他陆架区域不同地质时期海平面变化的研究成果:总体而言,上新世巽他陆架海平面比现在高50 ~ 100 m,之后随两极冰盖发育海平面逐渐下降,在第四纪海平面受冰盖消涨影响而周期性升降,波动幅度达130 m,记录较多的全新世研究显示了末次冰消期以来海平面的快速上升以及中全新世高海平面时期,近代观测表明最近200多年海平面呈上升趋势并且自20世纪开始上升加速。同时不同的研究方法和区域造成的结论差异说明海平面重建影响因素的复杂性和时空分布的多变性。
英文摘要: The sea level change is an important part of global change. It not only relates to the natural environment and ecological changes, but also has a significant impact on the economy and the development of human society. Understanding the sea level history and dynamic rule is a basic condition to build reliable models and improve the future forecast. Sunda Shelf is located between the Pacific Ocean and India Ocean. Owing to the feature of the second continental shelf area,wide shelf and gentle slope, Sunda Shelf is sensitive to sea-level change and an ideal place for sea level study. In this paper, we introduced the method of sea level reconstruction briefly, and reviewed the researches in the Sunda Shelf of different geological periods: Overall,the sea level in Sunda Shelf during Pliocene was as high as 50 ~100 m,then fell gradually along with the development of the polar ice sheets, and fluctuated among 130 m with the ice volume shrinking and growing in Quaternary. Holocene researches with the most records exhibited the fast elevating in the last deglaciation and the mid-Holocene highstand. Recent observations showed a rising trend of sea-level of past 200 years and the accelerating rate since twentieth century. Meanwhile, the divergence conclusions because of the various research method and regions indicated the complex of the influencing factors and the variability of the spatial and temporal distribution for the sea level reconstruction.
