| Along With the high-speed development of economy in Hefei,there is an outstanding image of increasing role of the urban road greening.This is to enhance humanities,life style and taste of a city.There are more and more applications about using the urban road greening with fancy plant.It not only makes up for the deficiency of the general single plant color,but it also plays an important role in saving the capital by purifying the air.Now on urban roads,the application of colored plants is limited to "use" only,while ignoring the based on its resources development,the form,color collocation planting and maintenance of the discussion,so that it can not fully display the beauty of color,the art of modeling and the essence of smell.In this paper,we focus on present situation of the application of urban road greening based on the four major districts in Hefei(Shushan district,Luyang district,Yaohai district,Baohe district)and select the 26 typical streets for field investigation and exploration.The content includes green space of streets,tree species of colored plants,planting mode,etc.Through the data records of colored tree species combined with theoretical knowledge,induce the current situation of urban road greening in Hefei area.By analyzing advantages and disadvantages and aiming at the existing problems in current situation,we bring up and apply solutions to the related cases.Through on-the-spot investigation and research,found the followings:1.Among all these 26 investigated streets in Hefei,there are 55 species in colorful leaf plants,belonging to 37 families,47 genera.With arbor 28 species,21 species of shrub,5herbaceous plants and 1 vine plant.Dosage proportion of big trees and shrubs is relatively high than vines,herbs.From color's perspective,leaves are yellow,white,red,brown,purple,red,etc.Red is majority and there is 49..09% of the total number of colorful leaf plants,followed by yellow,another is white.2.Colored plants have different viewing effect.They can be viewed as flowers,as leaves,as nuts and as bark.Some of the colored plants have different viewing effect in different seasons.Among all 55 investigated colored plants,there are 6 plants can be viewed through whole year,which takes up 10.9.The number of spring color leaf tree species is 17,accounting for 30.9% of the total.Summer is 8,accounting for 14.55% of the total.Fall is 21,which accounts for 38.18% of the total.Winter is 4,taking up 7.27% of the total.The most available for viewing in the fall is the visible color leaf tree species and it is also the most colorful season.3.The current Hefei widely used kinds of colored plants are pretty less,limited to the use of leguminosae,rosaceae,cashew and so on.But among these,the most widely used are sycamores,camphor,purple leaf barberry,privet,etc.It is very common to have mismatch in color,in species and the phenomenon such as the imperfection of the maintenance management of colored plants.Due to these problems,it causes the urban road greening colored plants in the same color,plant leakage and loess bare.4.According to the investigation of urban road greening on different colored plants.Urban road greening configuration has the following 11 types: 1.The trees single plant.2.Arbor + shrub.3.Arbor + grass cover.4.Arbor + hedge.5.Arbor + hedgerow + cover.6.The arbor + shrub + hedge.7.Being arbor + shrub + hedgerow +.8.Arbor + shrub + cover.9.Shrub + hedgerow + cover.10.Shrub + hedge.11.Hedge + cover.Colored plants trees of green belt use tree avenue system based model alone,more the rest of the roadside green belt,green belt,central green belt,the machine runs car traffic island green belt use two or more of the stratified planting enhanced stereo feeling.The article should provide the basic material for reference as preliminary research on the plant application in Hefei area for urban road greening plant application through the four major economic development zone in Hefei city road greening the and provide more information in developing green urban road in Hefei. |
