Abstract：A method extracting optimal index from desert index，normalized differential desert index，and modified soiladjust desert index was presented. The method is obtained by band math，based on the obvious differences between absorption and reflection of desert. The results of analysis with the TM image of Shanshan Kumu Tage in 1995，2000，2005 and 2010 using the optimal index indicate that the method is feasible.
