摘要：In order to make full use of the salt water resources in Cheng an County, Handan City, improve the availability of water resources in the region, and alleviate the shortage of water resources, so we simulated the change of groundwater salinity in this area. Based on the grey theory, a mathematical model was established for the groundwater salinity of the region from 2010 to 2015, and the actual depth was studied. The GM(1, N) model was established by analyzing the groundwater level, actual pumping amount and regional rainfall and other related factors, the GM(1, 1) model was used to simulate the area, and the simulation results of the two were compared. The result is that GM (1, N) model considering the factors is closer to the actual value of the mineralization degree fitting, and the simulation accuracy is higher. At the same time, the groundwater mineralization degree of the region from 2016 to 2020 is predicted. The results show that the groundwater salinity will change significantly in the next five years. Except for the decreasing trend of Da Zhai monitoring wells, the others are obviously rising.
