In this paper,the methods for leaf area index(LAI) and leaf angle distribution(LAD) retrieval areaddressed from the following three aspects:the theory and model of canopy structure parameters extraction,the retrieval of gap fraction,and clumping index.

从冠层结构参数的反演原理、冠层间隙度的提取、冠层结构的反演模型和丛生指数3个方面论述了冠层结构参数即叶面积指数(LAI,leaf area index)和叶倾角分布(LAD,leaf angle distribu-tion)的反演方法,并从鱼眼像片的采集、分析和模型的假设等方面分析影响冠层结构参数反演精度的原因,指出未来鱼眼影像技术虽然是LAI和LAD间接测量的理想手段,但是受观测环境、相机光学特性和冠层本身的影响,反演结果需要通过验证来消除不确定因素。

The relationships of initial culm number per clump,spatial distribution of culm and culm number per clump with the culm morphological variation of Bambusa ventricosa were studied.
