Abstract To determine impacts of ecological restoration on the Xiaofu River wetland, a two-dimensional water environment mathematical model based on the MIKE21 model was constructed, and the eutrophication hazard index H was used to assess water bloom prevention effects under eight different ecological restoration scenarios. The results from analyzing lake hydrodynamics and water quality evolution characteristics show that the model simulation error was smaller than 20%, and the determination coefficient for COD, ammonia nitrogen, total phosphorus, and total nitrogen was 0.8, 0.95, 0.94, 0.87 and 0.81, respectively. Under the same replenished water amount, a short-term water replenishment had superior effects, while under different water supply conditions, the large recharge water supply effect was better. Furthermore, under the same water supply conditions, the multi-point water supply was superior. An optimal ecological recharge scenario was the Option B8 which is a simultaneous upstream and downstream recharged with a total of 2 million m³ of water in 20 intervals.
