| In recent years, as China’s rapid urban road construction and the city continued to expand the scale of road green space landscape in rich urban landscape and the role of cities in improving the ecological environment is becoming prominent. Plant is the protagonist of green space, but also the landscape of urban road green space important part, taking into account the landscape and ecological features. Urban road green plant landscape not only plays beautify the city, improve an important role in the city’s image, but also to protect human health and living space and improve the main urban ecological environment, thus enhancing the construction of the theoretical and practical significance is very important urban road green landscape.Thesis summed up the car with the type of sub-urban roads, urban road green space landscape features, elements, design principles and the current situation and existing problems. Changsha City Xingsha road green space for the study of plant Xingsha road green landscape investigation and analysis. By all Xingsha road green road section in the form of plant species and frequency of application, growth conditions of plants, ornamental characteristics of plants, green plants configuration mode, status of plant community structure and various road car with stars plant landscape analysis reveals star sand road plants landscape in the overall status and application of species, and to explore the desirability of inadequate road green status quo existing in Xingsha region, proposed recommended species and plant species configuration mode, and some problems Xingsha road green areas exist, reasonable improvement measures put forward some reasonable reference proposal for the development of local roads Xingsha green.1 A survey of 26 Xingsha road, road section in the form of a plate with two plates and two-three band type. By Xingsha road car division of landscape survey found that:a plate with two road due to poor roadway too broad shade trees and the effect of the sub-band car plant landscape configuration is relatively simple, and some even only trees, watching less than shrubs and ground cover; road two plates three belts are usually the original road expansion or new construction, which are more plant species, landscape level is also relatively rich, and greatly improve traffic safety, played well separating traffic, improve and beautify the environment.2 The survey found that 85 plant species, genus and 57 families. Of which 32 kinds of trees, shrubs,31 kinds,19 kinds of herbs, vines one kind, two kinds of bamboo, plants, respectively,37.6% of the total,36.5%,22.4%,1.2%,2.3%. Different types of plants used in different frequency, the frequency of use of trees from high to low top eight followed by camphor, magnolia, complex bipinnata Luan trees, osmanthus, ginkgo, purple-leaf plum, cherry, Elaeocarpus, camphor which applied frequency 100%; shrub frequency from high to low top eight rubrum followed by wood, azalea, Pittosporum, camellia, Euonymus, Osmanthusfragrans, Photinia, lobular privet; frequency of use of the top three herbs They are:Radix, Verbena, Viola tricolor; only ivy vines; Fengweizhu only bamboo and bamboo seasons.3 Species investigation by car with road points, the frequency of application, ornamental characteristics, community structure, configuration mode, growth status and its sub-car with the landscape, analyzes its shortcomings:The road section in the form of green too simple; fewer trees species, growing different; plants lack of features; poor winter plant landscape effect; conservation ill; section spacing trees unreasonable. For the emergence of these problems, put forward the corresponding improvement suggestion:pay attention to the road car division with design; road green plant species diversity; emphasis Plants diversification; pay attention to plant seasonal changes; perfect post maintenance work; accordance with the "greening of urban road planning and design specifications "design.4 Based on the green tree species star sand road survey and summary, puts forward the recommended range of tree species, including trees, small trees, shrubs, etc. And respectively from the arbor+small arbor+shrub+cover, arbor+shrub+ cover, arbor+shrub and arbor+cover, shrub+cover these five kinds of configuration mode of star sand road greenbelt plant configuration mode were discussed. |
