Study On Application Of Plant Landscape In Autumn Landscape Of Changsha City

Autumn is the harvest season,also the beginning of all the dying season.Therefore,for the landscape,the plant on the fall is even more important.In 2016,Changsha City has completed the "three-year green action" which began in 2014.After three years of urban greening,the landscape of Changsha City has been radiant.The city’s plant landscape is colorful with the season changes and forms it’s seasonal characteristics,autumn plant landscape rich colors,thousands of shapes,mood long.The purposes and significances of this paper is to show how to use the plants with different styles in the autumn to show the charm of Changsha City.This paper was completed in 2017,at the same time,Changsha City is beginning the new round of green actions,this research can provide large reference recommendations to the green plan of Changsha City.This paper begins with the application theory of autumn garden plants,and summarizes the application types of autumn plants,such as autumn foliage plants,autumn flower plants,autumn view fruit plants,autumn view plants and autumn foliage plants.The main function of the autumn plants is the main focus of the visual impact,the formation of visual impact,and create a landscape theme,and from the perspective of the landscape analysis of autumn trees and rocks,water,architecture,garden roads and other elements of the garden.Studied the park green space(integrated park,special park),ancillary green space(residential green space,road green space,public facilities green space)in Changsha city.The results showed that there were 188 species of autumn plants,which belonged to 52 families and 95 genera.There are 89 species of trees,accounting for 47.9%of the total species;50 species of shrubs,26.1%of the total species;30 species of herbs,15.9%of the total species;11 species of vines,5.8%of the total;8 of aquatic plants,accounting for 4.3%of the total species.Among them,there were 184 species of autumn plants in two comprehensive parks,which belonged to 73 families and 132 genera.There were 176 species of autumn trees in three special parks,which belonged to 72 families and 127 genera.and 37 families,59 genera,73 species in 9 city roads.There are 107 species,52 families and 81 genera of autumn plants in 4 residential areas.57 families,97 genera and 140 species of autumn plant in 4 campus.Analyzed the landscape effect and landscape characteristics of autumn plants in Changsha.There are 10 species of high-frequency plants in the surveyed green land in Changsha,including Ginkgo biloba、Koelreuteriabipinnata、Prunus cerasiferaEhrhar、Cerasus serrulata var.lannesiana、A.palmatumvar.thunbergii、Acerpalmatum、Cassia bicapsularis、Wisteria sinensis、Sophora xanthantha、Berberis amurensis.The upper autumn plants are ginkgo biloba,Platanus,etc.,the middle of the autumn plants are mainly Japanese cherry,red maple,chicken feet maple,double pod Cassia,citrus,no thorn bone,And in the lower level of autumn plants are mainly Ophiopogon.In the color matching,Changsha City autumn trees are mainly monochrome configuration and color mix and match,which color mix and match mainly yellow + green,red + green,red + blue + green,yellow + purple +red + green,red + yellow + Green,yellow + red,yellow + purple,red + purple and so on.The problem for the applications are:the type is not rich,autumn plant community landscape similarity is high,plant configuration is not reasonable,lack of plant landscape theme.The main countermeasures are as follows:to enrich the species of autumn trees,to build high quality autumn plant communities,to plant with scientific means,combined with the deep cultural heritage of Changsha City and the characteristics of autumn plants to highlight the characteristics of autumn landscape plants,To create a landscape with the characteristics of the fall of Changsha.
