清原县冻土深度特征变化分析

Analysis on the Change of Frozen Soil Depth Characteristics in Qing-yuan County

对清原满族自治县国家基本气象站1962-2020年冻土器观测数据进行分析,得出清原满族自治县冻土深度变化与月平均气温之间的月、年变化特征。将冻土深度的年平均值、月值与月平均(最低、最高)气温等气象因素进行比较分析得到:一般温度越高,冻土深度越浅,反之冻土深度越深。通过比较分析得出清原满族自治县年冻土深度变化与气温呈负相关。

According to the analysis of the frozen soil observation data from the National Basic Meteorological Station of Qingyuan Manchu Autonomous County from 1962 to 2020,the monthly and annual characteristics of the permafrost depth change and the monthly average temperature in Qingyuan Manchu Autonomous County are obtained.Comparing the annual and monthly values of the frozen soil depth with the monthly average(minimum,maximum)temperature and other meteorological factors,we can get:Generally,the higher the temperature,the shallower the frozen soil depth,and vice versa.Through comparative analysis,it is concluded that the annual permafrost depth change in Qingyuan Manchu Autonomous County is negatively correlated with temperature.
