| Abstract: |
| 【Objective】The effective utilization coefficient of irrigation water is an important index to measure the level of irrigation water.【Method】In this paper, the effective utilization coefficient of irrigation water of different types and the whole area in Xing''an League is calculated by the “head-tail test”, and the influence factors were analyzed.【Result】The effective utilization coefficients of irrigation water in large irrigation area, medium irrigation area, small irrigation area and well irrigation areas of Xing''an League are 0.5102, 0.4629, 0.3957 and 0.6361, respectively. The effective utilization coefficients of irrigation water in the whole league is 0.5454. The effective utilization coefficient of irrigation water in Xing ''an League continues to rise, and the scale of irrigated areas, irrigation methods, investment and management of irrigated areas, water-saving irrigation area and regional rainfall all have a certain influence on it. 【Conclusion】Suggestions are put forward to further improve the estimation accuracy of the effective utilization coefficient of irrigation water and optimize the irrigation area. |
