Estimating or determining evapotranspiration accurately could promote water use efficiency. It might also provide the scientific basis for reasonable deployment of water resources and sustainable management on forest vegetation. Penman-Monteith Equation is widely used for estimating or determining plant evapotranspiration. This paper presented the development and the calculation method of Penman-Monteith Equation. The Penman-Monteith Equation and some modified Penman-Monteith equations were summarized. The present state, existing problems and future tendency of using Penman-Monteith Equation to study forest vegetation evapotranspiration were analyzed. It provides useful help or reference for further study and wider application of Penman-Monteith Equation.
