摘　　要：结合西吉王民井区域水文地质条件,从气压、降雨、李马河水库等对水位的影响进行频谱分析、回归分析、降雨量对比分析。结果表明:王民井水位变化主要受气压和降雨的影响;李马河水库建成时间与水位下降趋势变缓时间一致,对王民井水位动态变化可能产生影响,且水库的建成可能使区域地下水达到一种新的动态平衡。Based on the hydrogeological conditions of the Wangmin well area in Xiji and from air pressure,rainfall,Limahe Reservoir and other factors that affect the water level,this paper conducts spectrum analysis,regression analysis and rainfall comparison analysis.The results show that the water level changes of Wangmin well are mainly affected by air pressure and rainfall;the completion time of the Limahe Reservoir,which was built in the upper stream of the observation point in the second half of 2016,is consistent with the time when the water level decreased,which may affect the dynamic changes of water level of Wangmin well,and the completion of the reservoir may rebalance the regional groundwater dynamic.
