| 摘要: |
| 【目的】 田间灌溉水有效利用系数是反映灌溉水利用效率的关键指标，其测定与分析工作是改进区域灌溉方式、合理规划利用灌溉水的重要依据。【方法】本文针对有无地下水压采工程，在邯郸东部平原井灌区选取了四个不同的典型田块，采用首尾测算分析法设计了农田灌溉水有效利用系数试验方案，并于2019年开展了现场测定和对比分析，【结果】间接评价了地下水压采工程的效果，进而讨论了影响灌溉水有效利用系数的因素。【结论】测定结果表明：邯郸东部平原井灌区灌溉水有效利用系数较高，均高于0.80。各因素分析表明，地下水压采水利工程实施可明显提高灌溉水有效利用系数，灌溉方式、土壤质地亦会影响灌溉水利用系数。研究结果可为河北省灌溉水有效利用系数的测算提供数据支撑，同时为提升邯郸东部灌溉效率提供决策依据。 |

| Abstract: |
| 【Background】The North China Plain is a typical groundwater overpumping area, where water resources is lack. Because most of the water was supplied for agriculture in the North China Plain, the improvement of the irrigation water-utilization efficiency (IWUE for short) is particularly critical to reduce the regional water waste and restore the regional groundwater environment.【Objective】The IWUE coefficient can reflect IWUE directly, thus the accurate measuring and analyzing of this coefficient is crucial to improve the irrigation mode and increase the regional IWUE.【Method】The initial and ending calculation was selected in the IWUE experiment scheme of the Eastern Plain in Handan. Four groundwater irrigation fields were selected according to the distribution of groundwater over-pumping control project, surface irrigation mode and soil properties. Then, the site measurement and the related comparative analysis was implemented in 2019.【Results】The results indicate that, the IWUE coefficient is high and ranges from 0.83 and 0.91. The effectiveness of groundwater overpumping control project in Matou Village is remarkable and the corresponding IWUE is high, through reducing the water transportation loss, the IWUE of border irrigation field in Dongzhangliugu Village is higher than that of flooding irrigation field in Wangshuangta Village, through reducing the leakage and waste in the field, the IWUE is different as the soil properties is different due to the different water holding capacity. 【Conclusion】This research can provide data support for the IWUE statistic in Hebei Province, and provide a technical support to improve the water resources efficiency in Handan. |
