The Features Of Greenway Plant Landscape In The Inner City Of The 3rd Ring Road In Chengdu

Chengdu proposes to build a beautiful and livable park city,and requires the development of an international greenway that aims to embody the culture of Tianfu and Huamanrong City.The urban greenway is the greenway that people have the most contact with,and it is very popular among the citizens because of its convenient access and use.The greenway plant landscape is the main body that constitutes the greenway landscape.The urban greenways mostly depend on the streets and water banks,and are affected by traffic and commerce.Studying the urban greenway plant landscape characteristics in the urban areas can help the construction of urban greenways and contribute to urbanization.Alleviating problems and improving people’s well-being are of great help.This article takes green roads in the inner city of Chengdu’s Third Ring Road as the research object,divides the urban green roads into four types: urban riverside greenways,park greenways,streetland greenways,and road greenways.12 typical plots are selected for field investigation,Analyze the plant species,quantity and morphological composition,study the relationship between plant space,plants and surrounding environment,summarize and summarize the elements of urban greenway plants in Chengdu,plant space creation and plant collocation mode,and obtain the following results:(1)The greenway plants in the inner city of the 3rd ring road in Chengdu are rich in applications,mainly deciduous tree plants.There are 86 species of greening plants,belonging to 52 families,including 27 species of large and medium trees,accounting for31.39%,11 species of small trees,accounting for 12.79%,14 species of shrubs,accounting for 16.29%,planting shrubs and land There are 34 species,accounting for 39.53%.Deciduous plants account for more than evergreen plants in arbor species and quantity;medium and coarse plants are the main species and quantity in the arbor layer,and fine plants in the shrub layer account for more than medium and coarse plants;arbor layer and shrub The types and number of layers are mainly horizontally spreading plants.(2)The greenway plant space is dominated by semi-open spaces,the size of the space is strongly related to the type of greenway in the urban area,and the width of the green belt is related to the level of the adjacent road.The greenway and the surrounding environment are handled by collect the beautiful ones,and by unsightly shield.The greenway environment is mainly divided into three categories: buildings,roads,and rivers.The adjacent buildings block the vertical line of sight and keep the horizontal line of sight transparent.On the shore,the secondary viewing surface is separated by plant clusters.(3)Plant collocation modes mainly include arbor shrub and arbor.There are five types of plant collocation modes: appearance,culture,hierarchy,space,and sound insulation.There are 39 plant application types,while arbor and shrub There are 19 plant application types in the pattern,19 plant application types in the arbor mode,and 1 plant application type in the mirror mode.Arboretum and grass model plant applications accounted for road greenway>urban river greenway>park greenway,street greenbelt,arborescent plant application types accounted for park greenway>road greenway>urban riverside greenway,street greenbelt.
