The invention relates to a flue-cured tobacco aroma type and quality judgment intelligent evaluation method. The method is characterized by screening out aroma classification and aroma score principal component factors from tobacco aroma substances through a GRRF method; establishing a tobacco aroma style judgment model through GRRF+SVM and GRRF+RF methods; analyzing evaluation performance of the two methods through a 10 fold cross-validation method, wherein for classification evaluation results, adopting accuracy ACC and receiver operating characteristic curve as evaluation criterion, and for regression evaluation results, adopting Pearson's correlation coefficient and mean square error as evaluation criterion, and determining an optimal plan of a tobacco aroma type judgment model; and on the basis of the above, constructing a tobacco aroma type judgment online tool and carrying out evaluation on the aroma type and quality of tobaccos to be detected. The method can carry out analysis and judgment on aroma type characteristics of the tobaccos in different ecological areas objectively and accurately.
