摘要
探讨了农田水分平衡中主要因子──降水和蒸发的关系。估算了可能最大蒸发量与水分会亏量，并绘制其空间分布图。这对于掌握雅鲁藏布江中下游地区旱涝发生规律，制定合理的灌溉方案，及评价农业水分资源，具有一定的参考价值。
In order to master the law of drought or flood in the middle and lower reaches of the Yarlung Zangbo river, the relationship of the major factorsof the field water balance,precipitation and evaporation, is discussed, the potential maximum evaporation, the surplus and deficiency of moisture are calculated. The distributional maps are given.
