摘　　要：在首都圈西北部9条活动断裂上布置了17个土壤气氢气(H_2)测区,土壤气H_2浓度分别在2012年5月和2013年5月测量两次,测点共1105个.测量数据结果表明:(1)9条活动断裂上土壤气H_2的浓度在断裂附近明显高于非断裂区域;(2)9条活动断裂上土壤气H_2的浓度从西向东呈增大的趋势.首都圈西北部活动断裂带土壤气H_2的释放会引起大气电离层的扰动,有关活动断裂带土壤气H_2释放的进一步研究对大气环境变化研究有重要的意义.H2in soil gas was measured twice in seventeen sites in the nine faults in the northwest area of the capital region,China,in May 2012 and May 2013.The results indicated that the H2 concentrations in the soil gas from the nine faults had obvious anomalies.The H2 concentrations in soil gas increased from west to east in the nine faults in northwest of capital region.The release of H2 from faults would impact the ionosphere.It is very significant to carry on further study on the release of H2 from faults and its impact on atmospheric environment.
