Detailed Description

USLE模型中植被覆盖因子的定量估算

(1)   像元反射值模型:

式中,为第i波段像元的反射值; 为第i波段该像元第j端元组分反射值; 为该像元第j端元组分的丰度;为第i光谱波段误差项; m为光谱波段数;n为像元内端元组分数目。

(2)非线性混合模型:

  

式中,w为均值SSA(单一散射反照率); 为光谱波段; n为端元组分数目; j端元组分相关几何横截面; 为小地物群; 为密度; 为端元地物粒径大小; R(i,e)为二向反射SSA; I为人射角; e为视角; μ=cosi; ; H(μ) 为小地物间多向散射的函数。

(2)   线性回归模型:

式中,为植被覆盖度;  为归一化植破指数。
