摘要：Changes in groundwater levels provide important information for seismic monitoring and prediction, but groundwater-level changes can be caused by multiple factors that need to be analyzed carefully. In particular, the effects of changes in precipitation have masked information on activities internal to the Earth. It is therefore of great importance to effectively eliminate the influences of precipitation change on groundwater levels. Kaifeng Well Yu-11, whose water level has dropped remarkably in recent years, lies in a national earthquake key defense area. Based on daily well-water-level and precipitation data from Well Yu-11, this paper analyzes its water-level dynamics and precipitation variation characteristics using Pearson correlation and regression analysis methods. The results show that change in precipitation is not the cause of the abnormal drop in the water level of Well Yu-11.
