Evalution And Optimization Design Of The Three-dimensional Greening Of Urban Roads In Beijing City

Three-dimensional greening takes up less space and has a high green coverage rate,and has been widely used in recent years.In July 2020,the Beijing Municipal Planning and Land Commission issued the "Guidelines for the Urban Design Guidelines for Renewal and Governance of Streets in Beijing".It is proposed that the concept of streets should be re-knowledged,and road construction should shift from car-first to peoplefirst and high-end construction.Quality urban public environment.The threedimensional greening of roads can improve the air environment quality of the road,enhance the comfort of pedestrian walking experience,and improve the ecological environment quality of the road.This paper selects 90 typical three-dimensional greening landscapes of roads from the six districts of Beijing as the research object,and conducts a detailed investigation and analysis of the three-dimensional greening plant landscapes of typical roads in the urban area of Beijing,and uses SBE beauty evaluation analysis method and green vision rate.The calculation method analyzes and evaluates the plant species,color richness,hierarchy,etc.,summarizes and analyzes the current situation of the three-dimensional green landscape of Beijing urban roads,and proposes optimization strategies.Finally,it summarizes the optimization strategies and design methods of the three-dimensional greening of roads in Beijing’s urban areas,and provides a reference for the related three-dimensional greening of roads.The research content and conclusions are as follows:(1)Chapter 1,Beijing’s public ecological environment has been greatly improved in recent years,but there are still environmental problems such as traffic noise,exhaust gas pollution,and heat island effect;(2)Chapter 2 summarizes the current plant species composition and main planting forms of the three-dimensional greening of typical roads in the urban area of Beijing;(3)Chapter 3,using the SBE beauty degree evaluation method and the green viewing rate calculation method to construct a three-dimensional green landscape evaluation model for urban roads in Beijing,and to study and analyze the quality of the three-dimensional green landscape of roads in Beijing’s urban areas;(4)Chapter 4 analyzes the landscape factors that affect the three-dimensional greening of roads in Beijing,and then proposes relevant optimization and improvement suggestions;(5)Chapter 5,combined with optimization suggestions,gives targeted optimization design schemes;(6)Chapter Ⅵ gives a conclusion based on the above research and reflects on the deficiencies in the writing process.
