| 摘 要： | 本文选取华北地区观测条件较好的63口水位观测井资料,运用小波分析法去除各井水位资料中的短期高频信息,提取出能反映水位多年动态变化的趋势信息,并利用各井水位趋势变化数据反演出华北地区多年构造应力场变化图像,结合其它水文资料,探讨了华北地区近年来的构造应力场变化特征.

| Abstract: | In this paper,we 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,we 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 ... |
