This article, through summarizing the progresses in the evapotranspiration (ET0) methods research, analyzes representative ET0 computation methods emphasized on three periods of the world: modificative Penman, Penman-Monteith and standard ASCE-PM. We take 20th century 90's last stages and 21th century initial period's world newest 19 experimental achievements with lysimeter's actual value rating ET0 value as the foundations, analyzing general usage of the ET0 computational method regarding the different climatic conditions. Although the effect of PM method application is desirable in many areas, many local effects are still unsatisfactory; the method MP and so on are more suitable in part of areas; the PM and MP method are not popular, the special attention must be paid to the standard ASCE-PM method. In brief, these kinds of half theory (semi-empirical) methods only suit in certain areas.

通过对ET0计算公式研究进展的总结，分析了在世界上三个时期比较有代表性的计算蒸发腾发量(ET0)的主要公式：修正Penman公式、Penman-Monteith公式及标准ASCE-PM公式；以20世纪90年代末期和21世纪初期世界上最新的19个用Lysimeter实验值率定ET0计算值的实验成果为基础，对于不同气候条件下ET0计算方法的普适性分析评估认为：虽PM公式应用效果较好的地区较多，但也有不少地区效果欠佳，MP等公式在一部分地区较好，PM与MP公式并非普适性的，要特别关注标准ASCE-PM公式，总之，这类半理论公式均有一定的地区性。
