叶片辐射传输模型PROSPECT 理论研究

综述植物叶片辐射传输PROSPECT 模型的理论，并对其理论来源PLATE 模型作了扼要介绍。进一步研究叶片结构、叶片光学吸收参数和叶片反射率、透射率之间的非线性关系，给出如何用单层致密叶片迭代来表示多层非致密叶片的反射率、透射率。讨论了Stokes 光学系统理论及其在模型理论中的应用，并用复向量的方法证明其各向同性光学介质中反射率和透射率递推关系式。表明PROSPECT 模型基于良好的物理模型，在满足假设条件下，能够准确模拟叶片的反射率和透射率。

Research of PROSPECT leaf optical property model

We introduce the classical radiative transfer theory-PROSPECT and reviewed the PLATE model whose theory PROSPECT is based on． The transfer equation for the leaf reflectance and transmittance will be further discussed in its basic form for a plane-parallel，homogeneous plate with three optical parameters，absorption coefficient ( k) ，refraction coefficient ( n) and leaf structure ( N) ． The Stokes system is introduced，which is commonly used in radiative transfer equations． A solution for the leaf reflectance and transmittance is derived seriously by complex vector． Under limited conditons，the result from accurate modeling of the optical effect of leaf shows that the PROSPECT becomes popular radiative transter tool due to its physical model agreement with leaf structure．
