Construction and Application of a Comprehensive Evaluation System for Wild Native Groundcover Plant Resources in Nanshan National Park of Hunan Province
[Objective]It is to fully understand and potentially utilize the wild native groundcover plant species in Nanshan National Park of Hunan Province.[Method]Using the method of field investiga-tion and verification,a comprehensive evaluation model combining qualitative and quantitative analysis was established by using the analytic hierarchy process(AHP)model to comprehensively evaluate the development and utilization value of the 60 wild native groundcover plant resources in Nanshan National Park of Hunan Province.[Result](1)The 60 wild herbaceous flower species belonged to 40 families and 56 genera,most of which were Compositae(6 genera 6 species),Labiatae(4 genera 4 species),Liliaceae(3 genera 4 species),Grassulaceae(2 genera 3 species)and Iridaceae(2 genera 3 species)et al.(2)The weight values of growth features(0.438)and ornamental features(0.420)were higher in principal level of structural model for comprehensive evaluation;the composite factors weight values of growth potential(0.189),reproductive capacity(0.144),flower ornamental(0.123),and distribution range(0.105)were higher in factor level(all more than 0.100).(3)In the 60 wild native groundcover plants,there were 22 species of excellent groundcover in levelⅠ,24 species of good groundcover in lev-el Ⅱ,and 14 species of average groundcover in level Ⅲ.[Conclusion]The evaluation system can accu-rately reflect the characteristics of wild native groundcover resources in Nanshan National Park of Hunan Province,and provide reference for the selection and application of wild native groundcover resources in this area and similar areas.
