| Urban green space is an important part of urban ecosystem and human environment.With the improvement of aesthetic ability and ecological awareness,more and more urban residents no longer meet the simple urban “greening” and expect more high quality.,a unique urban green landscape.Therefore,the current urban greening needs to stand at a new height and build a green infrastructure that is more in line with the public's spiritual needs.Compared with other flower application forms such as flower beds,floral environments have the advantages of rich landscapes,varied seasons,diverse species,and many years of viewing,which are becoming more and more popular and have become an important form of landscaping in many cities.Most of the studies on flowerscapes in China have stayed in the basic knowledge introduction and plant application survey,and there is little research on flowerscape evaluation based on public perspective.This paper takes the flower environment in the urban area of Hefei city(within the second ring)as the research object,uses sample plots,selects 30 flower plots as research plots,and based on the field survey data obtained from the sample plots,and combines the analytic hierarchy process.The assessment system for flower borders was constructed using the form of a questionnaire to statistically analyze the public's assessment of the current flower border in Hefei.The main findings are as follows:(1)A total of 168 kinds of flower plants were involved in the survey plots,involving 58 families,of which 19 were in the first year and second year,69 were perennial flowers,63 were flowers and shrubs,and 17 were ornamental grasses.(2)Scientifically constructing the Hefei City flower public assessment model with the basic structure,ornamental nature,and ecology as the guideline,and 11 factors such as scale,terrain change,and plane form as indicators,and based on expert consultation,The weight values of the indicators of each level are determined,and the ranking of indicator weight values of the criterion level is ornamental> ecological> basic structure.(3)Established a flower grading evaluation system.The comprehensive assessment index of flower borders is between 80% and 100% for Grade I,60%~80%(including 80%)for Grade II,40%~60%.Between Grade 6(including 60%)is Grade III and 40% or less(including 40%)Grade IV,public assessment results show that there are 5 Flower Border Points and Grade II Grade of Comprehensive Assessment Grade 1 in Hefei City.There are 13 of them,3 of which are rated Grade III,and 3 are Grade IV,indicating that the overall status of Hefei's floral habitat is currently relatively good,and the public is more satisfied with the flower landscape effect.(4)The ornamental nature of the flower garden is the core of the construction.The public has a view of the site's micro-topography,close or zero distance viewing,rich plant color,elegant plant texture,aromatic plant smell,and various other landscape elements.A certain degree of preference.(5)The public expects to enjoy more landscapes in parks,residential areas and other places.On this basis,based on the current status of flower use and the problems found during the investigation,the development mode of “low-cost” flower borders was proposed.In this paper,through the investigation and public appraisal of flower use and its landscape structure in Hefei City,we explored a pattern of flower borders that meets the needs of the public,provided a theoretical basis for the application of urban flower borders,and helped to build more and higher quality.The flower landscape that is accepted and appreciated by urban residents. |
