摘要
在分析影响配水效率的各种因素基础上,结合引黄大型灌区配水系统的实际运行工况,从整体上给出了以轮灌组数为参数的区域配水量与配水效率之间的函数关系,与目前使用的选择典型渠道的常规计算方法对比分析,并用实测资料进行了检验。认为该整体评价方法更具科学性,就该方法在实际应用中的一些具体技术问题进行了研究和探讨,有助于大型灌区配水效率计算方法的改进和提高。
Based on the analysis of influencing factors for water allocation efficiency,and integrating the actual condition of water allocation system of large-sized irrigation district of the Yellow River diversion, the functional relationship between the regional allocation efficiency and water allocation quantity is established using the number of rotational irrigation groups as the parameter.The result of the calculation is compared with that of the present used method and verified according to the data observed.It is proved that the new calculation method is more representative.The specific technological issues of the method in practice use are studied and discussed,which is beneficial for the improvement of water allocation efficiency calculation of large-sized irrigation district.
