【摘要】 准确计算单井控制灌溉面积,关系到灌溉工程的规划、机井布置设计、工程项目的总投资及地下水的开采利用量,也是水利工作者经常需要考虑的问题。但是,我国现行的相关规范中却有不同的计算公式,其中有些符号相同,概念不同,容易给使用者带来混淆,该文对单井控制灌溉面积的不同计算公式及公式中的综合平均灌水定额和轮灌期两个概念进行探讨,提出公式在实际使用中需要注意的问题。更多还原

【Abstract】 It is significant to precisely calculate the single-well control area,which is not only related to the programme of irri-gation project,arrangement of motor-pumped well,total project investment and the exploitable groundwater resources,but also the main considering problem for the water conservancy workers. While,there are different equations to calculate the single-well control area in the current standard. At the same time,some equations have the same letter symbols with different conceptions, which can always make the users puzzled. The different calculated equations for the single-well control area,notions of compos-ite average irrigation quota and rotation irrigation period were discussed. Conclusively,some suggestions for the equation practi-cal use were presented.更多还原
