从史料记载看中国历史时期海面波动

广泛采用文字类海面变化“代用资料”是历史时期小尺度海面波动研究的重要手段，将史籍中有关海面波动的记载与考古学和沉积地层学证据相结合进行综合分析，可以初步认定：我国历史时期2ka年来，西汉至两晋为相对高海面时期（西汉晚期为显著高海面时期）；晋末至隋末为相对低海面时期，唐至南宋为相对高海面时期，尤其是8世纪，11世纪后期至13世纪初期出现显著高海面，而其间的唐末至五代，南宋后期至元初曾出现过海面下降；元明清时期总体为相对低海面时期，但在元中后期至明初，16世纪上半叶，17世纪末至18世纪初分别出现几次相对高海面。

PRELIMINARY APPROACH TO SEA-LEVEL CHANGE IN CHINA BASING CHINESE HISTORICAL DOCUMENTS

Literal proxy data about sea level change is an important and effective manner to research sea level change happened in historical period. Through analyzing written records which contain information about fluctuations in historical documents, in combination with archaeological and sedimentary proofs, preliminary conclusion is drawn about the sea level change in the past 2 000 years. Sea level is relatively high from West Han Dynasty to the West and East Jin Dynasty, especially in the late West Han Dynasty. During the end of Jin Dynasty to the late Sui Dynasty, sea level is relatively low. The Tang Dynasty and the Song Dynasty are high sea level periods, especially in the 8th century, and from the late 11th century to early 13th century, sea level is obviously high. Whereas from the late Tang Dynasty to the Five Dynasty and from the late South Song Dynasty to the early Yuan Dynasty, sea level downs. The Yuan Dynasty, Ming Dynasty and Qin Dynasty are generally high sea level periods, except that from the middle to late Yuan Dynasty to early Ming Dynasty, in the first half of the 16th century, from the end of 17th to the early 18th century, sea level is relatively high.
