摘要
以灌区灌溉年净效益最大为目标，以地下水和地表水的可供水量、作物需水量、机电井出水能力、机泵提水深度、除涝防渍埋深等为约束条件，优化计算不同水平年农业最优种植模式及各种水源的最优分配，并提出最佳的灌溉工程运行形式。
Taking the maximum annual net henefit of irrigation of an irrigation district as obect; and taking the Possiblequantity of water supply with surface water and groundwater, crops' water consumption, watr output of eIectromechanicalwell, mechanical pump's pumping depth, and the ewhedded depth for preventing waer-logging as constraint conditions; theoptimum aghcultund planting mode for different level years as well as optimum distribution of various water sources are calcu-lated optimally. And the optimum operation form of the irrigaion projects are presented also.
