摘要
Penm an-M on te ith公式是在蒸散研究中应用最多,也是变化形式最多的方法,该文在对目前Penm an-M on te ith模型在森林下垫面中应用总结的基础上,阐述了其中众多参数的意义和常用的确定方法,着重探讨了影响该模型精确性的关键因子净辐射、空气动力学阻力和冠层阻力的计算方法,并分析了Penm an-M on te ith模型在实际应用中存在的一些问题,提出了该模型在今后森林蒸散研究中发展的思路。
The Penman-Monteith model is an affective approach used widely and variously in evapotranspiration research. On the basis of summarizing the application of the Penman-Monteith model in forest underlying surface, the evaluating method and significance of many parameters were expounded. The calculating methods of the key parameters were discussed including net radiation, aerodynamics resistance and canopy layer stomatic resistance, some problems were analyzed and some suggestions were given for practical application of this model in forest evaportranspiration research.
