摘要:

太阳辐射是森林生态系统功能与服务得以维持并发展的基础, 对森林中的辐射传输过程进行建模对于理解森林生态系统过程具有重要意义。近年来, 三维辐射传输模型的迅速发展使得冠层辐射能量分布格局与动态的准确模拟成为可能。为更好地理解三维辐射传输模型以使其更有效地服务于森林生态系统研究, 该文从模型的原理、应用及发展趋势3个角度展开论述。首先简要介绍了辐射度方法、光线追踪法等森林三维辐射传输模型常用的原理及目前代表性的模型, 然后总结了三维辐射传输模型在森林生态系统研究中的应用, 最后对模型未来如何通过提高易用性、增加多模型耦合等方式更好地应用于森林生态系统研究进行了展望。随着森林生态系统大数据的积累与过程模型的不断完善, 三维辐射传输模型将在未来森林生态理论研究与实践中发挥更加重要的作用。

Abstract:

Solar radiation is fundamental to the maintenance and development of forest ecosystem functions and services. Therefore, modeling the radiation transfer process in forest is of great significance for understanding forest ecosystem processes. In recent years, the rapid development of three-dimensional radiative transfer models makes it possible to accurately simulate the distribution and dynamics of radiation within forest canopies. In order to better understand three-dimensional radiative transfer models and make them better serve forest ecosystem research, we review the principles, applications and future prospects of these models. Firstly, common principles of three-dimensional radiative transfer models such as radiosity and ray tracing are briefly introduced, and then the applications of three-dimensional radiative transfer models in forest ecosystem research are summarized. Finally, future opportunities of integrating multiple datasets and models to better facilitate forest ecosystem research, such as model coupling and making various models easier to use, are discussed. With the accumulation of ecological big data and improvement of ecosystem progress models, three-dimensional radiative transfer models will play a more important role in theoretical research and practices of forest ecology in the future.
