黄山现代季节性冻土与第四纪多年冻土的推算
Calculation on Present Seasonal Frozen Earth and Permaprost During the Quaternary of Mount Huangshan
【摘要】 本文根据黄山南北麓——黟县、太平县的现代气温与地温资料,求出其相关系数,建立气温与0cm、5cm、10cm、15cm和20cm深地温的一元回归方程。利用回归方程计算黄山不同高度不同深度的现代地温值,并推算现代季节性冻土的深度和冻结期。根据第四纪冰期时气温约降幅求出当时黄山各日平均气温值,在假定这一地区气温与地温相关关系不变的情况下,用回归方程求出当时不同深度的地温值。用第四纪冰期时一月份的地温及深度值,拟定出深度——地温对数曲线方程,并用其求出不同地点的最大冻结深度。根据推算结果,第四纪冰期时黄山有岛状多年冻土分布,属季风型冰缘环境。
【Abstract】 The situation of Mount Huangshan close to YiXian and TaiPing counties. Acording to present air temperature and ground temperature of the two counties, the authors have analysed these materials by the linear regression equations, and round to calculate present frozen earth condition of Mount Huangshan. Based on the dropping range of the air temperature during the Quaternary in the Middle China, the authors calculated month average air temperature of Mount Huangshan at that time, then calculated the ground temperature of different depth by the linear regression equations, and draw the curve firgures. After analysing the curve figures, the authors calculated the logarithm equations of the ground temperature of different depths, then to obtain the average maximum frozen depth during the Quaternary ice age. Acording to above materials, we know that there was isolated masses of permafrost of Mount Huangshan. And it was the periglacial environment of the monsoon—type.
【Key words】 Mount Huangshan; seasonal frozen earth; isolated masses of permoprost; periglacial environment of monsoom—type.;
