Figure 3. Model partitioning diagram In the numerical simulation of the quasi-ideal model, the simulation duration is 7200 days, and the time step is 30 days. Different situations were simulated for comparison. First, we investigated the groundwater flow between zone 1 and zone 2 by setting up five pumping wells in the study area and continuously pumping during the simulation duration of 7200 days. Moreover, to explore the natural recovery ability of the wetland, the pumping wells were shut down when they were pumped up to 3600 days, and the recovery of the wetland was analyzed from day 3600 to day 7200 under the condition that a cone of depression had been formed due to groundwater overexploitation. The model was then analyzed for parametric uncertainty, and three different values of hydraulic conductivity K were set during the simulation by describing the effect of changes in the hydraulic conductivity on wetland water flow through indicators such as the reduced base flow, induced infiltration and total water reduction, as well as analyzing the effect of different hydraulic conductivities on wetland recovery capacity under the condition of closing the pumping wells at 3600 days.
