通过对滇西北地区两个土壤逸出氢气与两个温泉逸出氢气观测点两年多时间全时段高精度连续观测数据的数理统计、与气象要素的相关性拟合、以及利用S变换对观测数据的周期成分进行分析,得到如下认识:滇西北地区温泉井逸出氢气的背景值要高于土壤逸出气,四个测点的观测数据总体呈现出锯齿状起伏的特点,浓度高值与低值往往存在较大差值,其中温泉逸出氢气高值异常与低值异常均有呈现,而土壤逸出氢气均表现出高值异常;滇西北地区温泉井逸出氢气具有清晰的年周期成分,以及相较年周期成分稍弱的半年周期成分,但不具有半日成分,而土壤逸出氢气不具有清晰的年周期成分,而呈现出相对清晰的半日周期成分;与气象要素的拟合结果来看,温泉逸出氢气浓度变化与气温、气压表现出一定的相关性,而土壤逸出氢气则与二者基本不相关,且土壤逸出气与温泉逸出气浓度均与降雨量不存在相关性。这与前人的研究结果有着较大差异,故认为断裂带痕量氢浓度与气象要素之间的相关性还有待之后的进一步分析研究。
- Abstract:
-
Through the mathematical statistics of high-precision continuous observation data of hydrogen emitted from two soil sites and two hot spring wells in northwestern Yunnan for more than two years,the correlation fitting with meteorological elements,and the analysis of the periodic components of the observation data by using S-trans?form,the following understandings are obtained:The background value of hydrogen emitted from hot spring wells in the northwestern Yunnan is higher than that from soil;the observation data of the four measurement sites gener?ally show the characteristic of zigzag fluctuations,and the high value and low value of concentration are often in a large difference. Among them, both high and low abnormal values of hydrogen emitted from hot spring wells are present, while only high abnormal values of hydrogen emitted from soil are observed. Hydrogen emitted from hot spring wells in northwestern Yunnan has clear annual periodic components and slightly weaker semi-annual period?ic components,but it does not have semi-diurnal components. However,hydrogen emitted from the soil does not have clear annual periodic components,but shows relatively clear semi-diurnal periodic components. From the fit?ting results with meteorological elements, the change in hydrogen concentration emitted from hot spring wells shows a certain correlation with atmospheric temperature and pressure,while hydrogen emitted from the soil is ba?sically not related to both. Moreover,there is no correlation between the concentration of gas emitted from soil and hot spring wells and rainfall,which is quite different from previous research results. Therefore,it is believed that the correlation between trace hydrogen concentration in fault zones and meteorological elements still needs further analysis and research.
