| 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. |
