| 【目的】在水资源短缺的半干旱地区，灌区水资源的合理利用已成为完善当地水资源系统管理的重要途径之一，可有效提高灌区水资源利用率。【方法】以实现灌区系统整体效益最大化为目的，满足冬小麦和夏玉米两种作物需水为前提，构建了区间两阶段模糊随机规划模型（TS-FSPM），对泾惠渠灌区地下水和地表水的联合利用进行优化配置。【结果】①在25%、50%、75%水平年，冬小麦地表水最优配水量分别为1.82-2.03?108 m3、1.90-2.10?108 m3、1.90-2.10?108 m3，地下水均为0.65?108 m3；夏玉米地表水最优配水量均为0.21?108 m3，地下水分别为0.01-0.04?108 m3、0.03-0.1?108 m3、0.03-0.1?108 m3。相较于最优配水量，在25%、50%、75%水平年，地表水应分别增引0.52-0.72?108 m3、0.75-0.95?108 m3、1.09-1.29?108 m3，地下水利用则分别增加0.15-0.18?108 m3、减少0.03-0.1?108 m3、0.14-0.21?108 m3。②在最优配水量下，灌区整体最大收益为1725.01-2417.73?106元，相较现状提高约14%。【结论】本文所建立区间两阶段模糊随机规划模型适用于灌区水资源优化配置研究，为保障水资源高效利用和水生态安全，泾惠渠灌区应增加地表引水，减少地下水开采。 |

| Abstract: |
| 【Objective】In the semi-arid area with shortage of water resources, the rational utilization of water resources in the irrigation area has become one of the important ways to improve the local water resources system management, which can effectively improve the utilization rate of water resources in the irrigation area.【Method】In order to maximize the overall benefits of the irrigation system and meet the water requirements of winter wheat and summer maize, an interval two-stage fuzzy stochastic programming model (TS-FSPM) was established to optimize the joint utilization of groundwater and surface water in the irrigation area. 【Result】① In 25%, 50% and 75% level years, the optimal water allocation of surface water for winter wheat was 1.82-2.03?108 m3, 1.90-2.10?108 m3 and 1.90-2.10?108 m3 respectively, and the groundwater was 0.65?108 m3; The optimal surface water distribution of summer maize was 0.21?108 m3, and the groundwater was 0.01-0.04?108 m3, 0.03-0.1?108 m3 and 0.03-0.1?108 m3 respectively. Compared with the optimal water allocation, surface water should be increased by 0.52-0.72?108 m3, 0.75-0.95?108 m3 and 1.09-1.29?108 m3 respectively in 25%, 50% and 75% level years, while the groundwater should be increased by 0.15-0.18?108 m3, reduced by 0.03-0.1?108 m3 and 0.14-0.21?108 m3 respectively. ② Under the optimal water distribution, the overall maximum income of the irrigation area was 1725.01-2417.73 ?106 yuan, which was about 14% higher than the current situation.【Conclusion】The TS-FSPM established in this paper was suitable for the study of optimal allocation of water resources in irrigation areas. In order to ensure efficient utilization of water resources and water ecological security, Jinghuiqu Irrigation Area should increase surface water diversion and reduce groundwater exploitation. |
