| 中文摘要: |
| 根据水资源平衡的原理，对井渠结合灌区的地表水和地下水进行联合优化调度，并采取地膜覆盖集雨种植节水技术和引洪补源技术，实现灌区水资源的高效可持续利用。实践表明：采取沟渠蓄水和大定额灌溉的补源方式，效果明显；采取地膜覆盖集雨种植节水技术，增产幅度达17.4%；采取水资源优化调度技术，平均净增效益3000元/hm2左右，并可实现水资源采补平衡。 |
| 英文摘要: |
| According to the principle of water resources balance, the model for describing coordinative optimal allocation of surface water and groundwater in well-canal combined irrigated area is proposed. Besides, the technique of rainwater collecting and mulching as well as the technique of groundwater replenishment by flood are used to realize the sustainable development of water resources. The experimental result indicates that the effect of adopting this integrated technique is remarkable. The yield of corn increases by 17.4% and the benefit increases 3000 Yuan/hm2, at the same time, the balance between water consumption and replenishment is realized. |
