摘　　要：根据蒸发的日变化过程，可以分析气候因子和下垫面状况对蒸发的影响程度和规律，本文通过中国科学院阿克苏水平衡试验站的观测实验，和我国甘肃省沙坡头、山东省禹城县、日本筑波市的一些干旱、半干旱及湿润地区的蒸发日变化过程进行了对比分析，论述了干旱区蒸发日变化的一些特点。The conclusions of analysis through the comparing study on daily evaporation at four ex perimental fields in China and Japan are:(1) The evaportranspiration of vegetation in arid land is more than it in humid area.(2) The evaporation from the surface of earth in arid land is stronger and the change of evaporation within a day is not so great as that in humid area, the evaporating time is 15 to 17 hours a day.(3) The crest value of evaporation in a day in arid land appears earlier than that in hu mid area and the crest value goes on loger in arid land.
