不连续植被二向性反射的几何光学与辐射传输一体化综合模型

    1.不连续植被冠辰的间隙和辐照能量的空间分布

(1) 不连续植被冠层内(从)任意高度的间隙率P(0)模型:

式中,间单位体积内球心平均数(体密度);是从给定高度h,一个反置的树冠沿方向的投影被平面所夹的体积。

(2) 在高度h处一个很薄的层截获的辐射强度分布模型:

2.离散植被冠层BRDF的一次散射和多次散射

(1) BRDF的一次散射分量:

式中,为植被冠层内一次散射向方向的逸出;是阳光直射地面又为观察者直接看到的反射;是阳光经冠层平均间隙率衰减后到地面为观察者直接看到 的反射;阳光经冠层衰减后到达地面的反射再经冠层衰减而为观察者所见的部分,并考虑叶热点。

(2) 离散植被冠层的“开放度”系数模型:
