Abstract The background and interference in remote sensing alteration information detection in different landscape units are two complicated and easily confused study objects. In this paper,the spatial geometric structural characteristics of spectral data of the remote sensing image are analyzed thoroughly. In addition,the relations between the background and the interference,the complexity of their relationship and the classification of the interfering objects are studied systematically in combination with the theories of spectral mixing models and probability distribution of stochastic variables. The discussion of these problems has provided important technical ideas for designing the optimal scheme for remote sensing alteration information detection,evaluating potentiality of the alteration information,and extracting the alteration information accurately.
