Research On The Design And Application Of Three-dimensional Greening In The Urban Street Landscape Of Qu Jiang New Area In Xi'an

Along with the comprehensive development of urbanization in our country,The urban building density increases day by day,but the urban green space area decreases day by day,the urban ecological environment needs to be improved urgently.It prompted the greening pattern reform,make it changed from traditional plane greening mode to three-dimensional planting mode.To study and discuss the solution of urban greening in China.Taking three-dimensional greening in urban street landscape space in qujiang new area of xi 'an as the research object.The research methods of literature review,case analysis,field research and case design were used and summary to sort out relevant theories,technical practices and policy implementation at home and abroad from multiple professional perspectives such as landscape construction and architecture.Firstly,it analyzes and summarizes the advanced three-dimensional greening design techniques and technical characteristics at home and abroad,so as to provide advanced guarantee basis for the design strategy of qujiang new area.Secondly,a hierarchical survey was conducted on the application forms of three-dimensional greening of commercial hotels,heritage parks,cultural squares,overpasses,traffic nodes and pedestrian paths in the core area of xi 'an qujiang new area to find out the existing deficiencies.At the same time,the principles of integrity,innovativeness and regionalism are applied to put forward the design methods of overall composition,plant texture application and color expression in the optimization design of three-dimensional greening.Under the guidance of this strategy,the optimization design of the threedimensional greening application in Qujiang New District of Xi'an will be carried out,verify the timeliness by the design and then provide new strategies and ideas for the desi gn and research of urban street three-dimensional greening in the future.
