试论VB程序在彭曼公式中的应用

Discussion on the Application of VB Program in Penman Formula

通过VB编程并结合彭曼公式的基本原理,简化了参考作物需水量的计算过程。该程序只需输入基本参数便可很快运算出结果,并结合实例说明了整个程序的运行过程和运行结果。该程序不仅可绘制作物需水量等值线图,而且为研究大气—植物—土壤系统提供了有利条件。

Through VB programming and connecting with the basic principles of Penman Formula,this paper simplifies the calculation process of the referential crop water requirement,which can quickly calculates the results just by inputting the basic parameters,and connecting with actual cases,illustrates the running process and the running results of the whole program that can be used not only to draw the isoline map of the crop water requirements but also to provide favorable conditions for studying the atmosphere-plant-soil system.
