摘要
分析了 1 998年怀来后郝窑测点断层气CO2 变化特征及其与影响因素地温和降雨的关系 .一般情况下该测点CO2 变化与地温呈正相关 .讨论了导致该测点断层气CO2 变化与地温呈负相关的原因 .认为 3月～ 6月初该测点CO2 测值与地温呈反向变化是张北 尚义 6 .2级地震的后效 ;6月中旬至 9月中旬的反向变化是由于降雨过多引起的 .介绍了 1 999年 1月 2 9日内蒙古锡林浩特 5 .2级地震及 3月 1 1日张北5 .6级地震前后该测点断层气CO2 的变化特征 .
The relationship between the characteristics of change of CO 2 in fault product gas in Houhaoyao,Huailai county in 1998 and influence factors,such as geotemperature and rainfall is analysed. The observation values of CO 2 in fault product gas and geotemperature change generally in synchronism. The reason of negative correlation between change of CO 2 and geotemperature is discussed.The negative correlation from March to early in June,1998 resulted from recovery process of CO 2 observation values from high to low after the Zhangbei Shangyi M S6.2 earthquake. The negative correlation from the middle of June to the middle of Sept.,1998 resulted from excessive rainfall during this period. The anomalous characteristics of CO 2 before and after the Xilinhaote M S5.2 earthquake, Inner Mongolia on January 29,1999 and the Zhangbei M S5.6 strong aftershock on March 11, 1999 are introduced.
