Hierarchical evaluation index system model was established for order important degree, order important degree evaluation method was put forward based on fuzzy hierarchy group entropy. In this method, in view of the first appraisal criterion levels weight, participating score experts weight equally and not the equal question, uses more succinct group eigenvalue method（GEM）and relative entropy model(REM) separately carries on the computation. The information content of target data in the evaluating indicator system was measured to confirm the weight of different plan. The dimension value of stationary index was effective transformed by using fuzzy mathematics. The application example has proven this method validity solving the appraisal problem in the order importance degree evaluation.
