A Study On The Formation Of Landscape Architecture Under The Guidance Of Environment

With the development of urban landscape and its construction,the design of landscape architecture is from bound to the dependence on design experience to the requirements of logic and science,thus supporting the control of complex forms under complex background conditions.The rational,precise and quantitative design guidance will play an increasingly important role in the landscape architectural design.However,the current quantitative research on landscape architecture is not enough to support such design needs.With the advancement of technology,more and more technologies and platforms for data collection,analysis and decision-making have emerged.The landscape design industry should keep up with the trend of the times,seize opportunities,strengthen interdisciplinary exchanges and cooperation,and gradually establish and improve the quantitative description and design guidance system of landscape architecture,which apply them practically to practical projects.This paper takes the landscape architecture in the artificially landscape environment under the background of urban environment as the research object,and takes the Nanjing park architecture as the research example.The sample of 17 landscape buildings in 4 parks is selected as the study object of this paper.Firstly,the research uses UAV tilt photography technology and uses ContextCapture Center software to process image data to generate high-resolution 3D real-time model based on real image texture,and obtain texture information and spatial geometric information that cannot be obtained by conventional photography.The measurement is corrected with the existing survey data.Secondly,based on the surface model data and surveying data of these landscape architecture examples,a total of 18 quantitative indicators are proposed from the aspects of the landscape architectural form quantification and the landscape environment quantification.Among them,the quantitative indicators of landscape architectural form are divided into three aspects: scale index,interface index and shape index.landscape environmental quantitative indicators are divided into four aspects: scale index,interface index,shape index and visibility index.Through the in-depth study of the quantitative methods and related technical means of the above indicators,the quantitative data results are obtained.Through data analysis and summary induction,the ideal threshold of the index and the analytical or mutual influence law of the fitting curve between some indicators are obtained.Thirdly,the scale indicators of landscape architecture and landscape environment are used as evaluated indicators,other indicators are used as evaluation indicators,and the weight of evaluation indicators is determined by AHP method.The relative scale indicators are used as comprehensive indicators and landscape architecture and environmental assessment system is established.Then,based on the above research results,the environment-constructed landscape architectural form generation system is constructed.The system guides the design of the landscape architecture through four stages: scale determination,shape presupposition,shape optimization and form generation.Finally,This paper applies the actual case application to the morphogenetic system through the Lanpu Design Project of Qingliangshan Park.,and through the design project of Yangming Academy of Fengle Pavilion Scenic Spot and the design project of Guanyaoshan Ruins Park Brick Museum,the research results are verified,the parts of the study that have a reference to design practice and those that still require further research are pointed out.
