Evaluation And Optimization Of Plant Landscape In Urban Residential Areas Based On Livable Theory

With the rapid development of urbanization,the problem of urban environmental pollution has emerged,and the living environment conditions have been seriously threatened.It is an inevitable trend of development to construct plant landscape environment of livable residential area.However,the construction and development of livable plant landscape in our country is not perfect,most of them are all the same,and there is no new idea.This paper is based on the relevant research foundation at home and abroad.Based on the theory of livable city,the connotation and theoretical research foundation of livable residential area are expounded,and the evaluation system of livable plant landscape is constructed based on the principles of ecological community,landscape aesthetics and artificial psychology.And the plant landscape of Taiyuan residential area The comprehensive evaluation of livability was carried out.Some problems in plant landscape design of residential area were also found,and the optimization scheme of plant landscape in livable residential area was put forwardIn order to make livability evaluation of urban residential area,we first conducted a field survey of the residential area of Taiyuan,and found that the design focus of green space landscape in Taiyuan residential area was mainly concentrated in central green space,group green space,green space beside roadside and road greenbelt.The total investigation of four kinds of green landscapes was carried out,including plant species,quantity and configuration.Based on the results of the survey,the data obtained are statistically analyzed.In the survey of the residential area,7%evergreen coniferous,evergreen broad-leaved deciduous vines 11.3%,62.6%,2.6%,6%and 7.8%herbaceous perennial flowers,flowers,aquatic plants and by 1.7%.The application of deciduous broad-leaved forest is the most,but the use of aquatic plants and vines is lessA combination of qualitative and quantitative indicators is used to evaluate the plant landscape in residential areas.It includes 1 target layers,4 standard layers and 21 program layers.Through scoring,the weight values of each index were as follows:spatial Space(0.4669)>ecology(0.2776)>humanity(0.1603)>aesthetics(0.0953).Among the 21 program level indicators,the proportion of place diversity is the largest,followed by the accessibility of the landscape.Using the established evaluation system,the green landscape of nine districts in Taiyuan is evaluated by fuzzy comprehensive evaluation.Reviews for "good" 2 areas,including Ferris stone,Bindong garden;comments for "general" 5 areas,including the city of Double Happiness,Yifen court,Riverside Garden,Datang four,Arima oasis;comments were "poor" 2 areas,including Changfeng District,Wen Hua yuan.
