植物与大气间的湍流交换——新方法介绍研究状况综述

TURBULENT EXCHANGE BETWEEN PLANTS AND THE ATMOSPHERE——AN INTRODUCTION TO NEW METHODS AND A SUMMARY OF THE CURRENT RESEARCH SITUATIONS

植物与大气之间的湍流交换是地球和大气系统中能量和物质循环的一个重要环节,也是土壤-植物-大气系统的重要研究内容之一。揭示这一交换环节的物理机制,了解地气系统中能量、水分和C0.2等物质的运动和转换规律,对于农业生产、数值气象预报,环境生态和气候变化等研究工作有诸多方面的意义,是地学界所共同关心的问题。近十年来,植物与大气之间相互作用的研究有了许多重要进展,传统的局地湍流交换模式的局限性已逐渐被认识,一些新的方法在这一领域中出现,其中高阶闭合模式和流轨模式是比较重要的探索途径。

Important progresses have been made in recent years in the studies of turbulent exchange between plants and the atmosphere. This report discusses the limitations of the local diffusion model and briefly introduces the higher-order closure model and trajectory models recently appeared in this field of research . overall . comments on these models are made in this paper to provide useful experience for reference and to develop ideas for further research.
