植被冠层间隙率的研究至今已有30多年的历史,间隙率模型研究一直沿着辐射传输方向和几何光学方向发展,取得了重要结果.本研究的目的在于结合辐射传输和几何光学方法发展一个统一的间隙率模型.1 植被冠层的物理与几何间隙率在前人的研究中,对植被冠层间隙率的概念未作任何区分,实际上,从不同角度出发,间隙率有着不同的含义,有进一步进行区分的必要.植冠间隙率的传统概念是个统计上的定
The research on the canopy gap has been more than 30 years old and the research on the model of the porosity has been carried out along the direction of the radiation transmission and the geometrical optics and has achieved important results.The purpose of this study is to combine the radiation transmission with the geometrical optics A uniform porosity model.1 Physical and geometric porosity of vegetation canopy In the previous studies, no distinction was made in the concept of vegetation canopy porosity. In fact, from different perspectives, the porosity has different meanings , There is a need for further differentiation.The traditional concept of crown clearance is a statistical
