Abstract According to the character of level structure of physical matter,this paper puts forward a multi-level detaching model for extraction of remote sensing alteration information based on several years' practice. Under the framework of this technical model,the simplification of the object for complicated extraction of remote sensing alteration information is discussed,and then the basic theory and structure of the model as well as the main technical system are discussed under the framework of the model and on the basis of an analysis of application instances. It is proved that the thinking of this model not only can simplify the problem of anomaly extraction but also is commendably applicable to the practice.
