| 摘 要： | 以河套灌区义长灌域永联试验区为研究对象,建立水均衡方程。首先,分析了水均衡法估算出的蒸散发量的合理性、蒸散发量与水均衡要素的关系以及根系层不同取土观测深度对水均衡法估算蒸散发量的影响。然后,分析了永联全区的水均衡要素构成以及土壤水和地下水的水分消耗过程。最后,分析水均衡法估算蒸散发量需注意的问题。

| Abstract: | In this paper,we take Yonglian test area in Hetao irrigation district for an example to set up the water balance model.Then,we analyze the reasonability of regional evapotranspiration estimated by water balance method,the relation between evapotranspiration and several main components of water balance,and the influence of different observation depths in unsaturated zone on estimated evapotranspiration.In addition,we analyze the components of water balance and mechanism of water consumption in Yonglian.Finally,we arrive at some conclusion on how to appmy water balance method. |
