项目摘要

The joint research by five universities are carried out from 1984 to 1986. Each researcher worked for his own purpose under taking the same aim at the design of upland water requirement and made investigation using the same prosedure.The results were reported or are going to be composed in 16 theses by each researcher, and the common part of these investigations about evapotranspiration, the fundamentals of upland irrigation project, are pickked out and discused in final report as follows.(1) From the point of view of the potential evaporation (Eo), Chugoku-Shikoku area and Kyushu area are divided into three specific sections in its meteorological characteristics respectively. And 5 investigation stations correspond with these divided sections of Nihon sea, Seto inland sea, North Kyusyu and South Kyushu each other, except South Shikoku and Central Kyushu.(2) Evapotranspiration calculated by Penman's equation(ETpen) has a good correlation coefficient with the actual evapotranspiration(ETa) in each station. The Eo calculated by Penman's equation using the data of regional meteorological station also shows a good correlation with the ETpen of the investigation site each other.(3) Evapotranspiration ratio of soy bean is arround 1.0-1.1 after growing to over about 2.0 of leaf area index (LAI). It is concluded that the evapotranspiration method by using Penman's equation is the most rational for the design of upland water requirement.

从1984年到1986年进行了五所大学的联合研究。每个研究人员都为自己的目的而努力，以同样的目的设计高地水需求，并使用相同的原告进行调查。报告结果或将是将是每位研究人员在16个论文中，以及这些有关蒸散剂的调查的共同部分，即陆地灌溉项目的基本原理，在最终报告中被挑出来，并不如下。（1）从潜在蒸发的角度来看（EO（EO）），Chugoku-Shikoku地区和Kyushu地区分别分为其气象特征的三个特定部分。和5个调查站与Nihon Sea，Seto Inland Sea，North Kyusyu和South Kyushu的这些分裂的部分相对应，除了South Shikoku和Kyushu中心外，彭曼方程（ETPEN）计算出的蒸发量（ETPEN）具有良好的相关系数。每个站点的实际蒸散量（ETA）。使用区域气象站数据计算得出的EO，还显示了与研究地点的Etpen彼此相关的良好相关性。（3）大豆豆的蒸散率在生长到超过2.0叶面积的2.0叶子之后，是1.0-1.1的。索引（LAI）。可以得出结论，使用Penman方程的蒸散方法是设计高地水需求的最合理的。
