| 摘 要： | 提出基于改进多目标决策模型的大桥水库灌区渠系自适应规划方法，合理规划大桥水库灌区渠系配水，提高水资源利用率，降低无效弃水以及对生态环境的影响。以配水结束后灌区各渠系缺水量、渠道输水损失量以及农作物生产带来的灰水足迹三者最小为大桥水库灌区渠系规划多目标决策函数，以渠道输水能力、水量和时间为约束条件，构建大桥水库灌区渠系规划的多目标决策模型；以栅格法构建路径规划的运行环境，通过移动几率优化、信息素挥发系数自适应调整两方面改进蚁群算法，通过改进蚁群算法寻优获取渠道缺水量、输水损失量、灰水足迹最小的水库灌区渠系规划结果。实验证明：该方法可以有效规划大桥水库灌区渠系的水资源，规划后的灌区渠系在缺水量、渠道输水损失量以及灰水足迹方面都有较好的表现，且效率高、应用性强。

| Abstract: | The adaptive planning method of the canal system in the Daqiao Reservoir Irrigation Area Based on the improved multi-objective decision-making model is proposed to reasonably plan the water distribution of the canal system in the Daqiao Reservoir irrigation area, improve the utilization rate of water resources, and reduce the ineffective waste water and the impact on the ecological environment. The multi-objective decision-making function for the canal system planning of Daqiao Reservoir irrigation area is to minimize the water shortage of each canal system in the irrigation area after the completion of water distribution, the loss of water conveyance through the canal and the grey water footprint brought by crop production. The multi-objective decision-making model for the canal system planning of Daqiao reservoir irrigation area is constructed with the water conveyance capacity, water volume and time of the canal as constraints; The grid method is used to build the operating environment of path planning, and the ant colony algorithm is improved through the optimization of moving probability and the self-adaptive adjustment of pheromone volatilization coefficient. Through the improved ant colony algorithm, the planning results of the reservoir irrigation area with the minimum water shortage, water transmission loss and grey water footprint are obtained. The experiment proves that this method can effectively plan the water resources of the canal system in the irrigation area of Daqiao Reservoir, and the planned canal system in the irrigation area has a good performance in water shortage, water transmission loss and grey water footprint, with high efficiency and strong applicability. |
