Study On Spatial Unit Morphology Of Landscape Built Environment

In the landscape architecture environment,the spatial unit is the most basic component of the spatial structure in landscape architecture.Spatial units are linked by paths to form a sequence,which in turn generates the overall structure of the landscape architecture environment.Therefore,the morphological composition and description methods of spatial units have always been one of important issues in the field of landscape architecture disciplines.In the past,the exploration of space originated in abstract fields such as philosophy and art,and its discourse was mostly qualitative,vague and specious.The rapid development of contemporary digital technology has provided a broader research direction and more diversified and precise scientific means for the study of spatial units in landscape architecture,giving us the opportunity and conditions to improve the imprecise descriptive language based on the traditional,empirical descriptions and judgments of the past by applying precise quantitative rules,conducting precise research on the deep properties and characteristics of spatial units,interpreting and describing the spatial units in a quantitative way,and guiding more precise and refined spatial design.In addition,the development of Smart3 D Capture,Pix4 D,Altizure and other large scale 3D scene rapid refinement modeling technology makes it possible to combine the research results and design applications with each other,which provides a grasp and platform for the research of complex space in the built environment of landscape architecture.In summary,this paper will focus on the morphological characteristics and composition of the spatial units of the landscape architecture,based on quantitative methods and digital technology,combined with Smart3 D Capture 3D modeling technology,to build a quantitative index system for the morphology of the spatial units,and explore its inner laws through quantitative analysis.Based on the morphological composition of the spatial units of the landscape architecture,this paper elaborates the morphological characteristics of the spatial units in four directions:enclosure,sparseness,shape and complexity,and proposes a total of 13 quantitative indexes to describe the spatial forms.The quantitative indexes are calculated and illustrated by multi-platform and multi-technology based on the selected typical spatial units designed by famous landscape architects with similar planning style and public recognition.The model data were obtained from 5-axis oblique photography and the Internet.Based on the calculation of a large number of spatial unit samples,the results of the quantitative data are statistically managed and analyzed to firstly summarize the ideal threshold range of the indexes,and secondly explore the fitting relationship between some quantitative indexes and the morphological parameters of spatial units and the related laws.The paper concludes with the design project of Huaihai Memorial Park in Shuyang,which is based on the above research results to guide the design construction and regulate the morphological composition of the spatial units in landscape architecture in four stages of spatial orientation,morphological pre-design,morphological optimization and morphological generation.By making full use of digital means to quantitatively describe the morphological characteristics of spatial units,decipher the mechanism behind the excellent landscape spatial environment,and explore the common laws of its composition,it can effectively promote the research on landscape spatial units from qualitative to a combination of quantitative and qualitative,and guide the regular,refined and precise landscape spatial design.
