Abstract:In order to establish the shallow groundwater level control index system in Guangping County, firstly the characteristics of the shallow groundwater level change in Guangping County were analyzed, and then the multiple regression analysis method was used to determine that the main influencing factor of the shallow groundwater level is the extraction volume, followed by Precipitation. Well irrigation return replenishment and canal irrigation field infiltration replenishment have no significant impact on shallow groundwater level, and control the rate of shallow groundwater drop and shallow groundwater extraction. Through the multiple linear regression analysis method and the inverse distance weighting method (IDW) in ArcGIS software, the control indicators for the lower limit of the groundwater level of each representative monitoring well, each township in different hydrological years in 2030 were obtained, thereby establishing a shallow layer Groundwater level control index system. The results show that by 2030, all townships in Guangping County will become areas where groundwater level is basically stable or water level rises. In 2030, the shallow groundwater level of Guangping County will be buried in different hydrological years. The lower limit control index is 31.69-34.66 m.
