摘要: 对太湖平原晚更新世末期以来的沉积物、生物化石、泥炭层、古文化考古等方面大量资料的分析研究,证明今太湖及其周边平原地区一直为陆相沉积环境。太湖是在平原洼地上积水而成的湖泊。太湖自形成后,面积逐渐扩大,由于湖流、风浪的侵蚀作用而逐渐成为现今的形状。

Abstract: Taihu Lake is situated in the Taihu Plain, south of the Changjiang River. It covers an area of 2338.1 square kilometres,and is one of the five large freshwater lakes in China. It is proved that the Taihu Plain was not transgressed extensively when there appeared a high sea level in the Middle Holocenc by the continental deposit on the Taihu Plain, many remains of ancient culture of the early and middle Neolithic period and the peat-buried sites 5000-6500 years ago. Taihu Lake was formed by river silting up and water confluence. Taihu Lake has a large area and shallow water. Disturbed by storm, the deposit at the bottom of the lake was very thin. Wave and lake current made the west and south banks on the lake in the shape of are. The area of the lake has been expanding since its formation. The peak period of expansion appeared in the warm time of the Sui and Tang dynasties.
