摘要
本文以单位面积管网造价最小为目标，导出了平地田间管网优化设计模型及支毛管压力差分配比例，可供微灌管网设计及灌水单元划分和支毛管布置等参考。
In this paper, an optimization model for the designof micro-irrigation pipe system in level land and the optimum proportion of pressure difference both in branches and laterals have been deducted according to the principle that the cost of per unit area of the network is kept minimum. It will be helpful for desian of micro-irrigation systam, division of micro-irrigation unit and determination of the length of branches and laterals.
