摘　　要：提出了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,可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、渠道输水损失量及农作物生产带来的灰水足迹3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。试验证明,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、渠道输水损失量及灰水足迹方面都有较好的表现,并且效率高、应用性强。Adaptive planning method of canal system in the Daqiao Reservoir irrigation area based on improved multi-objective decisionmaking model was proposed to reasonably plan water distribution of canal system in the Daqiao Reservoir irrigation area,improve utilization rate of water resources,and reduce ineffective waste water and impact on ecological environment.Multi-objective decision-making function for canal system planning of Daqiao Reservoir irrigation area was to minimize water shortage of each canal system in irrigation area after completion of water distribution,loss of water conveyance through canal and grey water footprint brought by crop production.The multi-objective decision-making model for canal system planning of Daqiao Reservoir irrigation area was constructed with water conveyance capacity,water volume and time of canal as constraints.Grid method was used to build operating environment of path planning,and ant colony algorithm was improved through optimization of moving probability and self-adaptive adjustment of pheromone volatilization coefficient.Through improved ant colony algorithm,planning results of reservoir irrigation area with minimum water shortage,water transmission loss and grey water footprint were obtained.Experiment proved that this method could effectively plan water resources of canal system in irrigation area of Daqiao Reservoir,and planned canal system in irrigation area had a good performance in water shortage,water transmission loss and grey water footprint,with high efficiency and strong applicability.
