Based on building distribution models assessment factors system of woody green plants,this paper chose 10 distribution models as samples in Guangzhou and researched on classifications of 10 assessment factors by using rough set.The results showed that: ①The significance of 5 assessment factors,which were proportion of trees and shrubs,the mean high of trees,the coverage of trees,the abundance of species and diversity of species,were respectively 0.1,0.2,0.3,0.1 and 0.3,and the others' significance were 0,which had a very small influence on the evaluation decision.②It can simplified and optimized the factors that we researched on classifications of distribution models assessment factors of woody green plants in Guangzhou based on the rough set,and the decision criteria obtained were accordant with practical situation.
