摘　　要：通过我国境内目前现有震例为研究对象,分析地震发生之前地下流体出现的异常情况,再根据异常时期地下流体的数据进行分析总结。结合相关文献显示,流体异常处于长期异常与中期异常时期时,基本都出现在距离震中五百公里左右的范围。针对地震前地下流体异常特征的监测与研究,其最主要的目的是为了判断高危地区的高密度观测特征。地下流体监测数据的获取、分析与研究可以为震前预测提供学术实验研究的数据支撑,从而能够更好的推动地震预测工作的发展。Through the existing earthquake cases in China as the research object,the abnormal situation of underground fluid before the earthquake is analyzed,and then the data of underground fluid in the abnormal period are analyzed and summarized.Combined with the relevant literature,when the fluid anomaly is in the period of long-term anomaly and medium-term anomaly,it basically occurs in the range of about 500 kilometers from the epicenter.The main purpose of monitoring and studying the characteristics of underground fluid anomalies before earthquakes is to judge the characteristics of high-density observation in high-risk areas.The acquisition,analysis and research of underground fluid monitoring data can provide academic experimental data support for pre-earthquake prediction,which can better promote the development of earthquake prediction.
