Evaluation on Ornamental Nature and Landscape Application of Pteridophytes in the Taibai Mountain
Ornamental values of 32 ferns occurring in the Nature Reserve in Taibai Mountain were evaluated by Delphi method. It was found that those with high ornamental values were Gymnocarpium jessoense (0.534) Ophioglossuum vulgatum (0. 502), Matteuccia intermedia (0. 474), and Dryopteris rosthornii (0. 457).
