It is refer to normalization of data in building of spatial database of soil and water loss assessing. The methods of data normalization are discussed based on the study of data normalization in building of spatial database of China potential soil and water loss assessing. The paper is made of the designing and the normalization of data. The normalization of data include the collecting and analyzing of data, the input of data, the change of projection, the change from other format to arc/info format and compiling the subject documentation.
