Quantitative Study On The Form Of Plant Communities In Landscape

As the basic component unit of garden green space,plant community is the basis for enriching landscape environment.Therefore,on the basis of rationally arranging plants according to the principle of zonality,it is important to study the morphological composition,quantity and quality of plant communities in park green space to improve the overall environmental level of the city.As the most intuitive visual factor,plant community morphology is one of the key factors determining the high quality of landscape environment.How to scientifically and accurately grasp the laws of its morphological composition has always lacked systematic research.With the development of digital China’s national strategy and related technologies,the study of plant community morphology should not be constrained by subjective qualitative description,and it needs multi-angle and systematic quantitative analysis.The aim of this paper is to synthesize these dominant and recessive characteristics and to form a scientific evaluation system covering various elements of community morphology,and explore how to rationally combine plant monomers to form a good plant community.According to the composition rules and the appearance representation of plant community,this paper chooses 6 quantifiable evaluation indexes to determine the ornamental value and spatial form of plant community,which are: shape and combination,height and level,density and distance,forest edge line and canopy line,species composition and color and texture,respectively.On this basis,the purpose of using quantitative research to guide the construction of plant landscape scientifically is realized in the real sense.In this paper,7 well-known urban gardens in Hangzhou and Nanjing are selected as samples for the in-depth analysis.And them are classified according to the types of common urban garden’s plant communities.On the basis of 31 typical community cases,the quantitative indicators of different configuration modes were analyzed and evaluated to explore the basic approach and morphological threshold of constructing beautiful plant community according to the study of the existing references and the practical investigation and research.And then,the optimal allocation paradigm of plant community morphology under different configuration modes was summarized.Finally,this paper takes the construction of Xinting Greenland in Yuhuatai District of Nanjing as an example,and provides a quantitative basis and new ideas for the morphological design of plant community,which has certain practical significance.
