| 英文摘要 | The commonly used irrigation system in the irrigation districts (with a combined irrigation area of 3.334 x 10(6) ha) along the lower yellow river of china is canal network. it delivers water from the yellow river to the fields, collects surface runoff and drainage from cropland, and stores both of them for subsequent irrigation uses. this paper developed a new combined irrigation, drainage, and storage (cids) module for the swat2000 model, simulated the multiple roles of the cids canal system, and estimated its performance in improving water reuse in the irrigation districts under different irrigation and water diversion scenarios. the simulation results show that the annual evapotranspiration (et) of the double-cropping winter wheat and summer maize was the highest under the full irrigation scenario (automatic irrigation), and the lowest under the no irrigation scenario. it varied between these two values when different irrigation schedules were adopted. precipitation could only meet the water requirement of the double-cropping system by 62-96% on an annual basis; that of the winter wheat by 32-36%, summer maize by 92-123%, and cotton by 87-98% on a seasonal basis. hence, effective irrigation management for winter wheat is critical to ensure high wheat yield in the study area. runoff generation was closely related to precipitation and influenced by irrigation. the highest and lowest annual runoff accounted for 19% and 11% of the annual precipitation under the full irrigation and no irrigation scenarios, respectively. nearly 70% of the annual runoff occurred during months of july and august due to the concentrated precipitation in these 2 months. the cids canals play an important role in delivering the diversion water from the yellow river, intercepting the surface runoff and drainage from cropland (inflow of the cids canal) and recharging the shallow aquifer for later use. roughly 14-26% of the simulated total flow in the cids canal system recharged shallow aquifer through canal seepage. the water flowing out of the canal system accounted for approximately 32% of the water in the cids canals. the storage capacity of the cids canals is negatively correlated to the precipitation. in years with abundant precipitation, the volume of the surface runoff and drainage from the cropland may surpass the storage capacities of the cids canals, while in years with less precipitation, partial storage capacity of the cids canal may be occupied by the diversion water from the yellow river. proper maintenance of the storage capacity of the cids has the potential in improving the efficiency of reusing the surface runoff and field drainage for irrigation practices to mitigate the increasing water shortage along the lower yellow river.
