昌黎台地电阻率近期变化的影响因素研究

Study on the influencing factors for the recent variationof the earth resistivity in Changli Seismostation

通过对昌黎台测区环境变化的调查和电测剖面、井液电阻率等测量结果 ,分析了该台近十年来电阻率变化发展的过程及其变化原因。结果表明测区附近热矿水的扩散、废污水的渗流和降雨等诸多因素的影响是昌黎台地电阻率多年趋势下降变化的主要原因。

Based on the investigation to the environment of the Changli Seismostation,its electromotive profile and its resistivity of well water,The reasons and the process of the earth resistivity's variation in the station are analyzed.The results show that the main reasons of the earth resistivity's reduction is the combining effect of the diffusion of hot mineral water,the vadose of waste water around the station and rain.
