摘要
准确模拟森林植被蒸散可以为提高水分利用效率、合理配置水资源、森林生态系统可持续经营管理提供科学依据。Penman-Monteith模型在蒸散研究中被广泛应用,本文介绍了该模型的发展情况和计算方法,总结分析了Penman-Monteith模型及其各种修正式在森林植被蒸散研究中的应用状况及存在的问题,并指出了今后的发展方向,以期为Penman-Monteith模型的进一步深入研究和广泛应用提供参考。
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.
