摘　　要：应用与断层活动有关的断层气资料研究断层的活动性 ,首先是要确定测区的背景值和异常下限 ,进而研究断层的活动性和分段特征 ,查找隐伏断裂及其产状 ,比较不同强震区断层气的异常值及峰值 ,判断潜在震源区的未来危险地段。重复测定活动断层的活动段以了解断层的动态变化 。After determining the background and abnormal threshold value of measuring area, the activity and section characteristics of fault can be researched by prospecting gas hydrargyrum and radon which spreadout from fault, buried fault and attitude can be found by this method. Compare the anomaly value peak value of fault product gas in different meizoseismal region, the future risk area of potential focal zone can be deduced by measuring the active section of fault repeatedly and observing the development of active fault, we can provide scientific basis for predict the relations between tendency of active fault and seimogenic relation.
