Abstract: 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.

Key words: Plant, Atmosphere, Exchange processes, Inverse methods
