摘　　要：由于现场条件限制,很难在末级渠道选出典型田块。即使在末级渠道选出了典型田块,但由于渠道是U型渠道,不便于设置简易量水槛,基于此,提出一种在典型田块里设置简易量水槛的明渠量水设施系统。该系统原理简单、方便实用、精度较高、造价低廉,可满足复杂条件下非末级渠道对应的水稻田的灌溉量水要求,并对设置量水设施系统具有一定的现场施工指导意义。Due to the constraints of the site conditions, it is difficult to select typical plots in the final channel. Even if a typical field is selected in the final channel, it is not convenient to set a simple water threshold because the channel is a U-shaped channel. Based on this, an open channel water measurement facility system with a simple water threshold in a typical field is proposed.. The principle of the system is simple, convenient and practical, with high accuracy and low cost. It can meet the requirements for irrigation water quantity of rice fields corresponding to non-last-stage channels under complex conditions, and it has certain site construction guidance significance for setting water measurement facility systems.
