摘　　要：介绍了研究植被与大气之间物质和能量交换过程的一个崭新理论———反演理论,主要包括拉格朗日方法、欧拉方法和欧拉-拉格朗日耦合方法.详细阐述了各种方法的理论框架,并简要说明了其应用范围,最后概述了反演理论的局限性和未来的发展方向.To estimate the source/sink and the vertical fluxes of mass and energy within and above plant canopies continues to be a critical research problem in biosphere-atmosphere exchange processes. The underlying approaches in such problem are to exploit the natural properties of turbulence within and above vegetation, such as Lagrangian inverse analysis, high order Eulerian closure model, and hybrid Eulerian-Lagrangian method. This paper introduced the recent development in multilayer turbulent transport methods to compute the distributions of the strengths of scalar sources and sinks within plant-atmosphere continuum, and in particular, focused on the so-called “inverse methods”, and described above three methods and their characteristics in detail. The limitation and prospect of these methods were also mentioned.
