本文发展了一个求解植被－大气相互作用的稳态分层模式。它结合了Ｎｏｒｍａｎ提出的植被层内辐射能传输模型和Ｗａｓｓｏｎｅｒ及Ｒｅｉｆｓｎｙｄｅｒ提出的求解通量的电路类比模型，推导了来自空中及地表面辐射能在植被层内传递的显式解，还推导了一套通用的联立方程组，把植被层内显热及潜热通量、空气的温度及水汽压等表示为只是叶温的函数。结果避免了以往一些模型不必要迭代．减少了计算机工作量。 In this paper, we develop a steady-state layered model for solving vegetation-atmosphere interactions. It combines the radiative energy transfer model proposed by Norman with the circuit analogy model proposed by Wassoner and Reifsnyder to solve the flux and deduces the explicit solution of the radiation energy from aerial and surface radiative transfer within the vegetation layer. The set of general simultaneous equations expresses the sensible and latent heat fluxes in the vegetation layer, the temperature of the air, the vapor pressure, etc. as a function of leaf temperature only. The result avoids the unnecessary iteration of some models in the past. Reduce the computer workload.
