The basic components of the inner-gully land in Loess-Plateau-Information-Geomorphic TUPU is Loess-mao and Loess-liang, which was extracted and analyzed based on the remote sensing image. The main contents are consist of five parts, including pre-disposal of image, image recognization, model-graph operation, database management and attribute-database management. Standard parameters and model-graph of each kind of Geo-info TUPU was built through extracting the boundary of each geomorphic unit, then the unknown kind of geomorphic unit can be classified into the corresponding databases by comparing with the model-graph after the extraction of the parameters. At last the next procedures are put forward.
