According to the ecological and biological characteristics of vine species and its utilization in urban landscape greening,we developed a multi-factor appraisal system that consists of 16 appraisal indices,for evaluating the exploitation and utilization value of vine species,based on the Analytic Hierarchy Process(AHP).A total of 81 ornamental vine species that were introduced and cultivating in South China Botanical Garden,the Chinese Academy of Sciences,were evaluated for their exploitation and utilization value,using this appraisal model.The results showed that some vine species has very high exploitation and utilization value,such as Bauhinia corymbosa,Heteropterys acutifolia,Cissus sicyoide,Piper hancei,Parthenocissus heterophylla,etc.;some others has high exploitation and utilization value,such as Philodendron oxycardium,Parthenocissus austro-orientalis,Cissus rhombifolia,Bauhinia glauca,etc.and some others has very low exploitation and utilization value,such as Piper sarmentosum Cocculus laurifolius etc.This method system and the results in this study were proved to be satisfied in accuracy and very useful for exploiting and utilizing the ornamental vine resources.
