摘　　要：在银川隐伏断层带已知断层位置的区段布设了两条土壤气H2测线,发现土壤气H2异常最高浓度位于银川隐伏主断层新渠稍探槽附近,含量达73.6×10-6,初步分析认为土壤气H2异常可能主要受断层活动性和倾角控制,说明土壤气H2测量对隐伏断层具有一定的指示意义。The concentrations of H2 in soil gas were surveyed along two lines,which crossed the known Yinchuan buried fault.The maximum abnormal concentration of H2 lying at the Xinqushao trench of the Yinchuan buried fault in soil gas was 73.6×10-6.It is suggested that the abnormal concentrations of H2 in soil gas were mostly influenced by the dip angle of the buried fault and the activity of the fault.Soil gas H2 measurement has certain indicative significance for the buried fault.
