作者首先给出海原活动断裂带从边沟至硝口的３条较长次级剪切断层、干盐池拉分盆地和边沟推挤构造区内的断层，以及尾端挤压构造区内的六盘山东麓逆断层的气氡、气汞浓度测量结果，然后分析了断层气浓度与断层活动性之间的关系。研究结果表明，在测试条件大体一致的基础上，气氡、气汞浓度与断层活动性之间有着明显的对应关系，从而证明了断层气测量方法对于活断层分段和活动性研究是一种有效的手段 The author first gives three long secondary shear faults in the Haiyuan active fault zone from the ditch to the mouth of the mouth, the faults in the Yanyanchi pull-apart basin and the ditch-pushing structural zone, and the The measurement results of gas radon and gas mercury concentrations in reverse faults in the eastern foot of Liupan Mountains, and then analyzed the relationship between fault gas concentration and fault activity. The results show that there is a clear correspondence between gas radon, gas and mercury concentrations and fault activity on the basis of the consistent testing conditions, which proves that the fault gas measurement method is a kind of study on active fault segmentation and activity effective measures
