Study On Suitable Plant Selection And Application Of Three-dimensional Greening In Taiyuan Residential Area

With the increasing development of urbanization,the problems of population,land and resources are becoming more and more prominent.The available area of urban greening is decreasing,and the problem of ecological pollution is constantly outstanding,which has caused great disturbance to the living environment.In this context,the need to promote the development of three-dimensional greening is also enhanced.Three dimensional greening is an important part of greening in residential area.For a specific city,choosing and determining suitable greening plants is the most basic realistic problem to do three-dimensional greening in residential area.At present,the plant selection and allocation of the three dimensional greening of Taiyuan residential area has not been systematically studied.The three dimensional greening of Taiyuan is late and slow in development,which is more obvious in the residential area.This study takes three dimensional greening plants in residential area of Taiyuan as the research object,and adopts the typical survey method of representative residential quarter to investigate and analyze the application status of three dimensional greening plants.On this basis,we evaluated and screened all kinds of stereoscopic greening plaints with good characteristics and carried out the design of typical planting patterns,so as to provide reference for the optimization and development of three dimensional greening in Taiyuan residential area.The results of the study are as follows:(1)The survey results show that there are three kinds of vertical greening in Taiyuan residential buildings,including roof greening,afforestation and wall greening.There are 53 species of plants,of which there are 6 species of tree species,9 shrubs,31 herbs and 7 vines.(2)Using the analytic hierarchy process(AHP)to make a comprehensive evaluation of the 375 plants selected preliminarily,and screened out 180 species of three dimensional greening plants in Taiyuan residential area,including 27 species of arbors,50 species of shrubs,60 species of herbs,and 43 species of lianas.In view of the specific application forms and conditions,the applicable plants selected above are applied to construct different configuration patterns of three dimensional greening plants.(3)This research method and the model can provide a reference for other types of plant selection;after this screening of species can be used as three-dimensional greening planning and design of residential district of Taiyuan city based transformation configuration mode for existing building three-dimensional green and new three-dimensional green,but also provide a reference for three-dimensional planning and design around and like the city.
