Abstract: According to habitat characteristics of Phoebe bournei regeneration layer and suggestions from experts, a habitat quality evaluation model was established for 7 habitat factors based on analytic hierarchy process. With the judgment matrix and uniform examination, the 7 habitat factors weight were determined in this model. The evaluation models of scoring criteria with 3 rating and grading standard of understory Pbournei regeneration layer habitat quality evaluation model were established using AHPfuzzy method.A overall evaluation on the habitat quality of understory Pbournei regeneration layer was made and the results showed that the model can provided some precision basis of theory for the application of development and utilization of forest regeneration layer.
