摘要
以往认为宁波组沉积时期的古气候为寒冷干燥或冷凉干燥。本文依据北仑B_(12)孔的孢粉资料,阐明在这一冷期中曾有一次相对较暖的气候波动,据此又可分冷凉—温和—温凉三个阶段,湿度以略湿为主。此外,还讨论了本区在晚大理冰期温度、湿度的变化特点。
The palaeo-climate of the period that Ningbo Formation-was deposited was considered having cold-dry or cool-dry features. In this paper, according to the sporo-pollen data of the drill hole-B12, Beilun harbour area, it is pointed out that there was a warmer climate-fluctuations in the cold period, and it can be divided into three stages: cold-cool, temperate, and temperate-cool. Ang the humidity mainly was slight humid. At the same time, the paper also discusses the features of the humidity and humidity variations of the post Dali glacial epoch of the area.
