| 多级渠系水资源优化调度是影响灌区水资源高效利用的重要因素。为降低配水时间、减少渗漏损失，以小海子灌区为例，利用斗渠轮灌分组和干渠分配流量作为决策变量，基于系统协调分解思想，考虑轮期约束和流量约束，构建双层粒子群优化配水耦合模型并求解。结果表明：采用双层粒子群优化算法能够有效协调多个下级函数，并且主函数的收敛状况良好；通过模型优化提出多级渠系配水方案，降低输水时间和渗漏损失值，整个灌水周期从2022年夏灌的实际126 d缩短至92 d，并且灌溉水有效利用系数提升9%。该研究可为小海子灌区的实际配水工作提供可行性方案，为灌区的水资源高效利用和可持续发展提供理论支撑和实践指导。 |

| Efficient scheduling of water resources in multilevel canal systems is critical for the optimal utilization of water in irrigation districts. Taking the Xiaohaizi Irrigation District as a case study, using the grouping of lateral canal for alternate irrigation and flow distribution of main canal, based on the idea of system coordination decomposition, a two\|tier particle swarm optimization\|based water distribution coupling model was developed and solved to minimize water distribution time and leakage losses, while accounting for rotational scheduling and flow constraints. The results demonstrated that the two\|tier particle swarm optimization algorithm effectively coordinated multiple subordinate functions while ensuring strong convergence of the main objective. Through model optimization, an efficient water distribution scheme for a multi\|stage canal system was proposed, significantly reducing water transport time and leakage losses. The entire irrigation cycle was shortened from the actual 126 days during the summer irrigation in 2022 to 92 days, and the effective utilization coefficient of irrigation water was increased by 9%. This study provides a practical solution for water distribution in the Xiaohaizi Irrigation District and offers both theoretical support and practical guidance for the sustainable management of water resources in irrigation areas. |
