%X This paper proposes a new unmixing method based on the simulation of real scenario. Fractions of the components are firstly obtained through the real scenario simulation. Then reflectance values of the endmembers (simulated endmembers) are calculated by combining the image reflectance values and corresponding simulated fractions. A constrained linear model is finally used to unmix pixels based on the simulated endmembers. Comparative analysis of the different endmember extraction methods, such as simulated endmembers, image endmembers, and reference endmembers, indicates that the simulated endmember method has the highest estimation accuracy and robustness for the crown closure of moso bamboo. The advantage of the real scenario simulation is to use field data as a priori knowledge for endmember extraction and introduce a three-dimensional simulation model into a two-dimensional linear spectral decomposition.
