摘　　要：渠系配水是一个复杂的动态过程，为此，建立了配水渠道流量优化调度０－１线性整数规划模型，并提出了各轮灌组引水时间均一化处理方法，使各轮灌组在同一引水时间结束灌溉，从而可使配水渠道进水闸能在同一时间关闭。模型运用于支渠以下各级配水渠道在来水流量确定，分水渠道流量彼此相同且按“定流量、变历时”方式轮灌时的优化配水方案决策。The water distribution of the canal system is a complex dynamic process, thus the 0 - 1 integral linear program- ming model of optimizing operation of distribution canals' discharges is established. And a uniformizing treatment method for diversion times of all rotation irrigation pops is presented also. This method can make that the all rotation irrigation groups end irrigation at the same diversion time. Therefore intake gates of distribution canals can shut down at same time. The model is suitable for the following conditions: all level distribution canals are smaller than the branch canal, all level distribution canals' discharges of incoming flows are determined, the diversion canals' discharges are same each other and making decisions according to the optimizing distribution scheme of 'constant discharge, variable durations' for rotation irrigation.
