浅谈大中型灌区场外输水干渠流量的确定方法

Large and Medium-sized Irrigation Water Flows on Outside the Method to Determine the Flow

针对大中型灌区往往由多个分灌区组成而各分灌区的灌溉制度、作物种植结构及灌溉水利用系数又有所不同的实际情况，通过计算分析整个灌区场外输水干渠的需水流量过程来确定的场外输水干渠规模更接近实际，为相似工程的设计提供有益的参考。

A large and medium-sized irrigation system composed by several small irrigation districts, which had different irrigation schemes, planting structure system and water use coefficient. Through calculation and analysis of the irrigation water amount in the whole irrigation area to determine the actual water flows, and to provide the beneficial reference to the similar projects.
