| Since the 18th National Congress of the Communist Party of China,with the deepening of the new urbanization process,the concept of cooperative development between large,medium and small cities and small towns has been widely recognized.People’s requirements for the environment of living in cities and towns have increased accordingly,and the landscape of roads and greenery plants is an important part of the urban appearance.This study is based on the aesthetic analysis and research of various types of road green plant landscapes in cities and towns,and uses the SBE method of the psychophysical model in the landscape beauty evaluation method to determine the beauty of the road green plant landscape of 16 streets in Jintang County.The first purpose is to evaluate the landscape quality of the main roads in the towns of Jintang County;secondly,analyze the existing problems and provide theoretical basis and suggestions for the future urban road green plant landscape planning and design;thirdly,to provide the urban road green plant landscape in the later stage provide reference for rectification and maintenance.In this study,the SBE value of each road was summarized by field investigation,photo shooting,slide making,selection of evaluators,implementation of evaluation procedures,and questionnaire survey on 16 main roads in the old and new towns of Jintang County.Then analyze the pros and cons of various types of road green space plant landscapes,the public aesthetic preference analysis,and the correlation analysis and difference analysis of road green space plant landscapes.The main results are as follows:1.Field surveys were conducted on road green spaces in Jintang City,and 16 representative streets were selected for integrated analysis.The results showed that there are40 kinds of garden plants(including varieties,subspecies and cultivars)mainly used for urban road greening in Jintang County.Among 32 families and 35 genera,in this survey,the author found that there are some plants with a high occurrence rate,mainly Moraceae(6 species),Lauraceae(5 species),Oleaceae(8 species),Rosaceae(5 species),Compositae(4 species),Labiatae(4 species);through the analysis of the quantitative characteristics,species diversity,and vertical structure of plant communities of various types of plant landscapes in the road green space,the results show that the current road plant structure in Jintang County is mainly in the form of arbor + ground cover;the vertical structure of the car-separated green belts on both sides of the new city is mainly shrubs + ground cover plants;the plant configuration of the roadside green space is mainly arbor-shrubs the form of the ground cover;2.According to the questionnaire survey of local residents,residents pay more attention to the road green plant landscape.Depend on the current living environment,they believe that the road green plant landscape gap between the new and old urban areas is too large,which is mainly reflected in the plant species,road landscape characteristics,and vertical structure and other issues;3.In the ranking of SBE beauty degree evaluation method,the comprehensive standardized values of 16 streets are ranked as follows: Binjiang Road Section 1> Shili Avenue> Yingbin Avenue Section 1> Nanbin Road> Huiguan Road> Xingfu Road> Cultural Street> Kangning Street> Yong’an Street 2 Section> Guangjin Highway> Fuxing Street>Jiangcheng Road> Wanfang Street> Jinsha Street> Sanjiang Road> Juyuan Road;4.The roads with better comprehensive value of landscape effects obtained through the evaluation method of plant landscape beauty degree,summarizes its plant composition mode and design key points,and the selection and configuration of plants for urban road greening,including ecology,local selection and color diversity.The specific principles of landscape design should include road section design,reasonable setting of green belts,vertical greening application,road border plants,spatial coordination,etc.By addressing the problems of urban life-type roads and traffic-type roads with poor results and low evaluation scores among the four types of road green space types.By drawing and investigating the status quo of the road section,the road optimizes the design of a reasonable plant configuration model,increases the types of road green space,so that the new and old urban areas achieve a harmonious and unified development trend,so that the image of Jintang can be better presented,in order to achieve the goal of Jintang Provide valuable suggestions and opinions on the construction of urban road green space plant landscape. |
