| 摘 要： | 为研究断裂与断层氢气间的关系,围绕依兰-伊通断裂方正-萝北段开展断层氢气浓度流动观测工作,得到该段断裂氢气浓度变化特征。结果表明:在时间尺度上,氢气浓度存在年变规律特征,主要受温度、湿度和微生物活动的影响,一年中夏季氢气浓度最高,春秋季最低;在空间尺度上,依兰-伊通断裂北段呈南低北高的分段性特征,氢气浓度高值地区对应地震活动较强的地区,低值地区对应地震活动较弱的地区,这与当前地震活动特征相符,说明断层氢气浓度与当前地震构造活动具有较好的耦合关系。

| Abstract: | In order to study the relationship between the fault and fault hydrogen, the hydrogen concentration of the fault was observed for Fangzheng-Luobei section of Yilan-Yitong fault, and the variation characteristics of the hydrogen concentration of the fault were obtained. The results show that, on the time scale, the hydrogen concentration has an annual variation, which is mainly affected by temperature, humidity and microbial activity. The hydrogen concentration is highest in summer and lowest in spring and autumn. On the spatial scale, the northern segment of Yilan-Yitong fault is characterized by low in the south and high in the north. The areas with high hydrogen concentration correspond to the areas with strong seismic activity, while the areas with low hydrogen concentration correspond to the areas with weak seismic activity. This feature is consistent with the current seismic activity, indicating that the fault gas concentration has a good coupling relationship with the current seismic tectonic activity. |
