The invention discloses an analysis method for the tobacco leaf style characteristic variation trend in the lamina aging process. The analysis method sequentially includes the steps that samples are taken and stored; tobacco leaf style characteristic indexes are graded and screened; the zero-value indexes and the no-variation indexes are deleted, the variation indexes are selected as tobacco leaf style characteristic evaluation indexes; evaluation data are processed in a normalization mode; an evaluation index projection objective function is built; optimization solution is carried out on the projection objective function; tobacco leaf style characteristics are comprehensively evaluated; according to the comprehensive evaluation data, longitudinal data resources are built for parameter estimation to obtain influence factors with significant differences, the factors are compared in a linearly independent pairwise mode to finally obtain the tobacco leaf style characteristic variation trend. The tobacco leaf style characteristics are comprehensively evaluated, and the optimal ageing use time of a tobacco leaf raw material can be fast determined; the analysis method has the advantages of being easy to operate, low in cost, high in evaluation speed and high in evaluation precision and accuracy, and evaluation results takes the various characteristics into consideration.
