Study On Road Greening Landscape Of Third Ring Road In Xi'an City

With the rapid improvement of people's material and cultural level,the connotation about urban road construction is also constantly enriching and improving.Xi'an Third Ring Road is the main traffic road to and from the city and its green landscape construction is become into a microcosm of the city.Along with the gratifying achievements in urban greening in Xi'an,the landscape plants of the Third Ring Road have been planted for ten years.Over the years,some unreasonable greening activities have destroyed the original greening design system,makes many regions of the plant configuration in a chaotic state.How to upgrade the road landscape of the Third Ring Road so that its plant landscape construction can keep pace with the construction of Xi'an and reach a leading level.Therefore,it is the purpose and significance of this thesis to provide theoretical reference for promoting the construction of Xi'an characteristic cultural landscape.Based on the theory of urban road greening landscape and ten years of work experience in the field,the author through literature collection and field investigation,based on the typical case study of road greening upgrading and transformation at home and abroad,this thesis mainly introduces the investigation and analysis of the current situation of road greening in the Third Ring Road,and discusses the landscape evaluation and existing problems of the landscape.At last,puts forward the upgrading and reconstruction strategy of the road greening landscape of the Third Ring Road.Based on these analysis and evaluation,draw some conclusions as following:1.Through the survey,Xi'an Third Ring Road green land planted 120 species,belonging to 43 families and 84 genera.Among them,there are 15 species of color-leafed plants and 12 species of herbaceous plants.2.The evaluation of the green landscape of Xi'an Third Ring Road shows that the evaluation value of road greening is 7.69 points.The evaluation results of plant application,conservation management and landscape characteristics of urban road green space are all ordinary.3.Through the analysis of domestic and foreign cases of road greening,successful cases of road greening have integrated ecological concepts into landscape design,achieved economical greening transformation,and paid attention to the application of native plants,the rational allocation of plants,and the embodiment of urban cultural characteristics.4.The investigation shows that the local turf has solved the problem of loess exposure for a long time,and has improved the ecological efficiency of Banpo Bridge under low-cost operation.Reasonable plastic pruning and appropriate increase in the application of leaf plants can improve the ornamental effect of road greening.5.Combining with the upgrading and transformation of the greening landscape of the Third Ring Road,the transformation strategies are put forward: building the greening landscape with local characteristics,choosing the plants with strong resistance to stress to build the economizing road greening landscape,constructing the multi-layer road landscape forest belt with scientific plant configuration,improving the ecological benefits,creating important nodes and integrating local culture to enhance the cultural grade of road greening.
