Abstract
Keerqin sand land is located in the transitional terrain between the Northeast Plain and Inner Mongolia (42°41′–45°15′N, 118°35′–123°30′E) in Northeast China and it is seriously affected by desertification. According to the configuration and ecotope of the earth's surface, the coverage of vegetation, occupation ratio of bare sandy land and the soil texture were selected as evaluation indexes by using the field investigation data. The evaluation index system of Keerqin sandy desertification was established by using Remote Sensing data, and the occupation ratio of bare sandy land was obtained by mixed spectrum model. This index system is validated by the field investigation data and results indicate that it is suitable for the desertification evaluation of Keerqin.
