摘　　要：传统方法构建分析模型时,缺失一组灌区测算样点数据,导致不同片区的测算结果高度一致,不符合地区农田实际,因此研究全新的测算方法。该方法重新选定涵盖小型农田水利工程灌区的测算样点,根据计算所得灌溉水相关参数,构建分析模型,测算田间水利用系数。实验结果表明,此次提出的测算方法,其测算结果更符合实际。When the traditional method is used to construct the analysis model,a group of sample data of irrigation area is missing,which leads to the high consistency of calculation results in different areas,which does not conform to the actual situation of farmland in the region.According to the relevant parameters of irrigation water,an analysis model was established to calculate the field water utilization coefficient.The experimental results show that the calculation results of the proposed method are more in line with the actual situation.
