Whereas groundwater numerical simulation is an essential part of groundwater environmental impact analysis, the authors propose a more accurate and suitable method for identifying and predicting the groundwater environment, laying a scientific basis for groundwater environmental impact evaluation.Targeted at the river and lake connection project in Jilin Province, this paper establishes a groundwater prediction model based on the groundwater modelling system (GMS), and considers the land salinization risk posed by the variation in groundwater level after the water diversion of the project.The results show that the depth of phreatic water in each area is greater than the upper limit of ecological water level after the implementation of the project plan, leaving a small chance for soil salinization.
