BOREAS中北部针叶林的短波辐射传输测量结果及建模(英文)

Shortwave Radiation Transfer of Conifer Boreal Forests During BPREAS:Results of Measurement and Modeling

通过ＢＯＲＥＡＳ实验，我们研究了北部森林植物群落对气候变化所起的作用。对针叶林地带太阳辐射通量的测量表明在辐射场中有重要的方向效应。这些效应主要与树林的分布及树冠结构有关。一个简单的方向传输模型可以解释在观测结果中的一个重要的角度特征。

The role of Boreal forest biome in climate change has been investigated through the BOREAS experiment. Measurements of solar fluxes in conifer stands show important directional effects in the radiation field. These effects are mainly related to tree sarrangement and crown architecture. A simple model of direct transmittance can explain an important angular signature observed on the results.
