摘要
In this paper, the authors selected 63 wells in North China region, which have better observing conditions. Using wavelet analysis method to remove the short-term low-frequency information in the water level data, the authors extracted the tendency signals which can reflect the dynamic changes of groundwater level. Change patterns of tectonic stress field in the North China region was inversed by using groundwater level data, and the tectonic stress field variation of North China region in recent years was discussed in respect to other hydrology data.
