摘　　要：灌溉配水优化模型旨在解决渠道各分水口运行时流量调度的最优组合方案,常规的轮灌分组模型只适用于分水口相同流量情况,且采用以小时为单位的各引水时段作为状态变量,变量多,求解不易。对于分水口的流量不相同的情况,提出了以引水开闸时刻和引水结束时刻作为优化变量,以灌溉期总流量保持恒定为目标函数的优化模型,该模型自然满足一次性引水约束条件。采用了多点交叉的改进遗传算法对该模型进行优化求解,提高了收敛速度,优化结果表明该优化模型及求解方法较好地解决了分水口非等流量的问题,具有普遍的适用意义。Irrigation optimization model is aimed to obtain optimal outlet flow distribution scheme in a distribution channel. The normal rotation irrigation optimization model is usually applied in the situation of equal outlet flow and optimization variables in hour are adopted, which make it difficult to get solution. The irrigation optimization model with unequal outlet flow is put forward which use starting time and end time as optimization variables and aimed to keep total irrigation flow constant. In the end, the optimization result is gotten by Genetic Algorithm（GA） with multi-point crossover method.
