新乡及其邻区地下水宏观异常浅析
|
摘要
20 0 3年 4月至 2 0 0 3年年底 ,河南省新乡市及其邻区 80 0余平方千米范围内出现了水井翻花、冒泡的现象。其历时之长 ,范围之广 ,实属罕见。研究认为 :由于前一年冬季降水量较大 ,土壤中有机物质经过充分的生物化学作用贮存有大量的CO2 气体 ,在发生一些中小地震前后 ,区域应力场的变化使得这一地区土壤中的气体集中释放。
From April to the end of 2003, there appeared roll and bubbles in a lot of wells in broad area of about 800?km2 in Xinxiang and its adjacent area in Henan Province. It is bizarre that such macro-anomaly lasted in a long period and in an extensive scope. The study suggests that there is a large amount of CO 2 in soil by the approach of adequate organic material by bio-chemical affect caused the larger precipitation in the previous year. CO 2 in soil released tremendously before and after some middle and small earthquakes.
