Abstract：Based on the overview of water resources in Jintan District of Changzhou City,Jiangsu Province,the combined model of WinSRFR model(for surface water irrigation)and SWAP model(for groundwater irrigation)was used to optimize the efficiency of agricultural water conservancy irrigation.The results show that the required irrigation depth of the project area is about 75 mm simulated by the SWAP model,whereas the irrigation depth simulated by the WinSRFR model can be significantly reduced.And the latter increases the irrigation efficiency from 47%to 92%.Optimization of irrigation schemes using the improved WinSRFR model can achieve effective water conservation and increase crop yield.
