摘要

采用多元线性回归方法,对昌黎地电台地电阻率与气象因素(气温、气压、降水量)进行相关性分析,多年数据显示,气温对地电阻率的影响系数最大,其次为气压、降水量.采用2015-2016年地电阻率多极距观测实验数据,与地下水位进行相关性分析,结果显示:由浅至深各层地电阻率与浅层水位均呈负相关变化,表层地电阻率无年变特征,且与浅水位同步性较好;随着探测深度的增加,地电阻率冬高夏低的年变特征逐渐明显.

Abstract

The multiple linear regression method was used to analyze the correlation between the resistivity of the Changli Station and meteorological factors(temperature,pressure,and precipitation).The multi-year data show that the temperature has the largest influence coefficient,followed by pressure and precipitation.The correlation analysis between the multipole distance observation results of earth resistivity and groundwater level from 2015 to 2016 shows that the ground resistivity of each layer has a negative correlation with the shallow water level.The most surface resistivity has the best synchronization with the shallow water level without annual change,which mainly reflects the dynamic change of the surface aquifer.With the increase of detection depth,the yearly variation of ground resistivity is gradually obvious,higher in winter and lower in summer.
