森林冠层反射模型

 

(1)    森林冠层的反射系数因子可表示为4个成分的和;

 

 

式中,是由树木冠层的单重散射导致的反射系数;是地面植被及土壤的单重散射导致的反射系数;是树冠层的多重散射导致的反射系数;是地面植被的多重散射导致的反射系数。

 

 

 

式中,是单位地面面积上第类树木的数量;是叶面积在冠层中的体积密度分布;是入射方向为,散射方向为的冠层介质的散射相函数;是顶角;是方位角;是在第类树的冠层中从点出发沿方向的路径都通畅的概率,即双向间隙概率;参数表示树的分布对泊松分布的偏差。

 

(2)    第二个成分的计算式为:

 

 

式中,是地面植被的反射因子;是在z=0时,即在地面植被高度上的双向间隙概率。

 

 

式中,是树冠层的多重散射的漫反射率;是归一化常数。

 

(3)    地面植被的多重散射反射给为:

 

 

式中,是在地面高度上总的下行散射通量;是归一化常数。
