[0166] The present invention will be further described below in conjunction with the accompanying drawings.
[0167] The present invention adopts the improved SAILH canopy model based on the hot spot effect, firstly classifies the given parameters, and divides them into two parts: leaf parameters and canopy parameters, and then uses the physical and chemical parameters of the leaves to calculate the basic absorption of the leaves, and then The reflectance and transmittance of a single-layer flat plate are derived from the calculation of the transmittance under the action of no interface absorption, and finally the spectral information of the leaves under the given structural parameters is derived by using the layering theory; at the same time, for the canopy parameters, the given leaf inclination angle is first used The distribution model parameters are used to calculate the leaf type distribution elements, and then combined with the calculated geometric elements to calculate t...
