Objective:In order to enrich the diversity of garden plants in the Hulunbuir and screen out local flower species with high ornamental value and regional characteristics.Methods:The Analytic Hi-erarchy Process(AHP)method was used to comprehensively evaluate 230 wild flowers in the Hulun-buir grassland.A comprehensive evaluation model for wild flowers in Hulunbuir grassland was estab-lished by selecting 13 evaluation indicators from three aspects:ornamental value of flowers and fruits,ornamental value of stems and leaves,and development potential.Based on the construction of a judg-ment matrix using AHP,the total weight of each evaluation index was calculated,and the evaluation index was scored through field observation results.Finally,the comprehensive score of each plant was calculated and graded.Results:The order of weight of each constraint layer to the target layer was orna-mental value of flowers and fruits,development value,and ornamental value of stems and leaves.Among the 13 standard layer evaluation factors,flower and fruit color,diameter of flowers,antirever-sion force,flower and fruit quantity,and plant appearance had the greatest impact on the ornamental value of wild flowers.Conclusions:According to the evaluation results,wild flowers in the Hulunbuir grassland had been rated as Grade I flowers,such as Sphaerophysa salsula,Pulsatilla patens var.Mul-tifida,Lychnis fulgens,Oxytropis myriophylla,Cypripedium guttatum,Lilium pumilum,Aquilegia oxysepala,Cypripedium macranthos,which had high ornamental value and could be domesticated and cultivated on a large scale for garden viewing.Wild flowers rated as Grade II,such as Iris dichotoma,Trollius ledebouri,Anemone silvestris,Epilobium angustifolium,Aster alpinus,Trifolium lupinaster,Astragalus dahuricus,Pedicularis resupinata,Campanula punctate,Chrysanthemum zawadskii,Sau-ssurea ulchella,Senecio flammeus,Melampyrum roseum,had high ornamental value and could be moderately cultivated and utilized.
