Evaluation of Resources and Ornamental Characteristics of Fern in Quchi River, Songzi City, Jingzhou

Abstract

Taking Quchi River, Songzi City, Jingzhou, Hubei Province as the survey site, the ornamental characteristics of local ferns resources were investigated and counted, and the ornamental value of 26 species of ferns was comprehensively evaluated by the analytic hierarchy process (AHP). Three evaluation criteria and 15 evaluation factors were selected to establish the appraisal system of ornamental characteristics of ferns in Quchi River, The ornamental grade of 26 species of ferns was divided in order to provide a basis for the application of ferns in landscape architecture. The results showed that the weight of leaves was the highest among the first-grade indexes, which was the most important index affecting the ornamental value of ferns. In the secondary indicators, the weight of leaf shape, young leaf color, leaf rarity and leaf color on the ornamental value of ferns is more than 10%, which has a great impact on the evaluation results. Among the participating plants, the comprehensive evaluation of grade I included Brainea insig-nis , Struthiopteris eburnea , Lygodium japonicum , Aleuritopteris argentea, Odontosoria chinensis , and Selaginella tamariscina . These six kinds of ferns have high ornamental value and have good garden application prospects.
