根据地下流体前兆异常落实工作指南，对福建闽清梅埔井水位大幅下降的成因作分析，通过观测技术系统故障、水口水库排水干扰、趋势动态、抽水干扰等因素的排除，认为闽清梅埔井水位呈规律性下降是固体潮固有韵律，非外界干扰引起；而水位大幅下降则有可能是区域应力情况的真实反映，可能反映了井区周围断裂活动的加剧。

The reason for the water level decline is discussed in Minqing Meipu Well according to the guidebook about the work of subsurface fluid precursor anomaly implementation．Through removing the damage of technique system, the drain interference of Shuikou reservoir, the dynamic trending factor and the interference of pumping water, we made the conclusion that the regular decline of water level in Minqing Meipu Well is not caused by surrounding area interference, but the regulation of solid tide; the great decline of water level is the really reflection of regional stress field in the station and it possibly reflects the tectonic activity of the surrounding area of the well.
