Under guidance of the general theory and method of synthetic information of mineral appraisal, 107 areas were classified by geological unit methods in Guizhou，taken 18 areas of Au deposit concentrated regions as model units and 89 areas of  anomaly concentrated regions as prediction units, the theory of quantification IV was used to classify all the samples and established the model of orientation prediction for all the same samples by the way of character analysis. And extended the application of model units of Au deposit concentrated regions into the field of the Au anomaly concentrated regions. All the units base on the probabilities of forming gold mine were classified. 22 working areas with more developed value in future were selected. The orientation prediction drawing of Au anomaly concentrated regions in Guizhou was finished. It provides some scientific proofs to the field in orientation prediction of large gold mineral deposit concentrated regions in Guizhou province.
