【摘要】 <正> 近十几年来,我国对海面升降变化的研究已取得了较明显的进展。海面变化不仅是海洋地质—地貌学中的一个重要的理论问题,也是现代构造活动研究的重要内容之一,并且对于国民经济也具有一定的意义。本文通过对海平面变化特定标志的分析研究,结合邻近海区及有关资料,对本研究区的海平面变化的历史进程和现代构造活动及其关系作一初步探讨。更多还原

【Abstract】 In light of the analysis on spectal indicators of ancient sea level and other data the changing sea levels of Holocene in Lower Yangtze are reconstracted. By the formula a:-r=H:(X-H)+(b-rt) the calculated highest sea level is 2.8m higher than the current sea level. An approach to the relation between the changing sea levels and the vertical crustal movement and recent tectonism has been made in the paper.更多还原
