| 摘要: |
| 通过对麦田水分微循环规律的研究，提出了描述降水（灌水）入渗、地下潜水蒸发（或补给）、根区土壤水分传输、根系吸水和蒸发蒸腾等五个子系统的麦田“五水”（大气水、地面水、地下水、土壤水和植物水）转化动力学模式。论述了模型参数的测取方法。经大田初步试验表明，该模型对于模拟麦田水分动态和“五水”转化关系具有较高的精度。 |

| Abstract: |
| Based on the research of the laws of water micro-circle process in winter wheat field, the dynamic of model of "five kinds of water" (air water, surface water,ground water, soil water and plant water) interrelation has been presented in this paper, which includes five sub-systems of precipitation and irrigation water infiltration,ground water evaportion,soil water movement in the root zone,water uptake by roots and crop evaportanspiration,Also the methods of the model parameter taking and measurement have been discussed.the results of the field application has shown that the model has a high precision in simulating the water dymamic state and "five kinds of water" interrelation in winter wheat field. |
