摘要：

Two analytical models of vegetation canopy reflectance are combined. The new model considers the diffuse and specular reflection of optical radiation on leaves, the canopy hot spot and nonlambertian soil. Diffuse fluxes are treated in a four-stream approximation. An elliptical distribution has been used for leaf inclination. Comparisons of the models demonstrate a good agreement. The FORTRAN-77 code of the model can be used in MS-DOS and UNIX environment. A complete set of algorithms of the new model is appended.
