摘要:

使用2021年唐山地区196个测点的土壤气Rn通量数据,结合2010年测量得到的土壤气浓度数据,研究了唐山地区土壤气体Rn通量的地球化学特征及其控制因素。结果表明:①土壤气Rn通量范围为0.01～409.31 mBq/(m²·s),平均值为40.58 mBq/(m²·s),高值分布在断裂带或断裂带交汇位置; ②唐山地区土壤气Rn浓度与通量高值空间分布有较好的一致性,在研究区北部,较低的b值与土壤气Rn通量的高值空间对应关系较好; ③ Rn通量测量受环境(地温、气温与海拔)影响较小,并与近期小震活动相关不明显; ④土壤气Rn通量和浓度与b值的空间分布特征一致,Rn高通量与高浓度对应低b值,表明土壤气Rn脱气强度可能与活动断裂带的高渗透性以及高应力有关。

Abstract:

Using the data of the flux of soil gas Rn measured by us at 196 points in Tangshan region in 2021,together with the data of the soil gas concentrations measured in this region in 2010,we study the geochemical variation and the controlling factors of the flux of soil gas Rn.The results show that:①The flux of soil gas Rn ranges from 0.01 to 409.31 mBq/(m²·s),with a mean value of 40.58 mBq/(m²·s).The high values are distributed in the fault zones or interaction parts of the fault zones.②The concentration of soil gas Rn is consistent with the spatial distribution of high values of the flux.In the northern part of the study area,the lower b-values spatially correspond well with the high values of the flux of soil gas Rn.③Rn flux measurements are less sensitive to the environmental factors(ground temperature,air temperature and elevation),and are insignificantly related to the activity of present-day,small earthquakes.④Fluxes and concentrations of soil gas Rn are consistent with the spatial distribution of b-values; high fluxes and high concentrations corresponding to low b-values.This suggests that the intensity of the degassing of soil gas Rn may be related to the high permeability of active fault zones and the high stress in the active fault zones.
