摘要: 本文介绍了1991年在禹城站用五种方法,同时测定和计算小麦的蒸发量,结果发现:1)无论15分钟短时间的,或一日的,或长时期(20天)累计蒸发量,包文比能量平衡法的结果与涡旋相关法、空气动力学法、水量平衡法的结果十分接近。2)土壤蒸渗器所测的蒸发,比所有其他方法均显着偏低。3)证明了土壤蒸渗器本身的工作性能和称重系统是基本正常的。4)试验和计算说明地下水直接参与了对土壤水分补给和蒸发过程,它在水量平衡中的作用已达到30%.5)土壤蒸渗器结果偏低的原因是由于它完全切割了地下水的补给,在高地下水埋深的地方,是不适用的。禹城站新近安装的36吨大型土壤蒸渗器,可以模拟地下水变化,有待进一步的试验。

Abstract: An experiment was conducted in the Yucheng Experimental Station to testify the validity and reliability of the evapotranspiration measurements by the lysimeter and the Bowen-ratio Energe Budget Method.The eddy-correlation technique was used as a reference for all the other methods,meanwhile,the aerodynamic method and the water balance method were also adopted in the experiment.The Yucheng Experimental region has high ground water talbe ranging from 3 to 1.5 meter,Particularly,in recent 5 years,the ground water table has raised by about 70 cm.

Key words: ground water tables, lysimeter, Bowen-ratio energy budget method, eddy-correlation method, water balance method
