At present, the project has entered the construction stage, and will be fully completed by the end of April.Wuxi section of Shanghai Nanjing ExpresswayOn the 100 sides of the Wuxi se

12、ction of the Shanghai Nanjing Expressway, the afforestation control line is made. The location of afforestation is the ecological protection landscape forest belt, which is mainly composed of tall, fast growing and native trees and dotted with local decorations. According to the highway traffic fast

13、, closed management features, the main function of the protective green belt is to protect the ecological environment and road traffic on both sides of the landscape, forest of fast-growing, tall, raw native trees for forest change overall color, Ji Xiang and skyline attention in the design of the m

14、ain le. Emphasis on ecological protection function, and national highway, Wuxi section of protective green belts constitute our citys important compound green ecological corridor.Wuxi Nanjing Expressway length of 43.62 kilometers, afforestation area of 9660 acres, of which Xishan District 9.68 kilom

15、eters, divided into 3 construction section; Huishan District 18.86 kilometers, divided into 9 sections of the construction area; 15.08 kilometers, divided into 4 construction section.1, the situation before reform and the main problems1.1 central dividerBefore modification, the following problems ex

16、isted in the greening of the central divider:(1) the layout of the anti dazzle tree is simple and inflexible;(2) the tree species are monotonous, and the selection of individual tree species is improper (such as the law of the Qing Dynasty);(3) trees and grasses are all green,Plain color;(4) some se

17、ctions of the central road have been filled with lime soil. When planting, they did not change, fill and cultivate soil, resulting in the death of some trees.1.2 slopesThe slope greening construction period mainly from the angle of the slope stability of embankment, the grass planting protection, fo

18、r the hybrid bermuda. For Nanjing and Zhenjiang sections, the top slope of the cut is protected by stone masonry and no plant protection is considered. Therefore, the transformation of the front slope greening mainly has the problems of rigid and rigid slope protection and poor landscape effect.1.3

19、interworkingThe construction period of the main interchange greening from conducive to traffic safety, convenient for custody and control of the investment perspective, the scope stipulated in enclosed within the ramp of the grass, the appropriate planting shrubs some resistance to cutting, forming

20、plants, and best regular geometric pattern. The main problem is the existence of the transformation of the former interchange green small green area, and the magnificent exchange does not adapt, and the pattern is stiff, with the surrounding environment is not harmonious, can not reflect the local c

21、ustoms and practices and cultural connotation along.1.4 service areaDuring the construction period, the service areas have been properly beautified, mainly planting lawns, building some sketches and planting some flowers. The main problems of greening before the reform are the lack of features, inco

22、mpatible with the beautiful buildings in the service area, and the lack of humanistic, historical and folk customs.1.5 reserved lanesThe highway on both sides of the reserved 4m wide six lane widening land, construction period no green building, after the opening of only sporadically planted some tr

23、ees, the lack of scientific configuration, is basically a blank section of green, far from Easy Access requirements.2, the guiding ideology and basic principles of greening transformationIn addition to lack of funds, the lack of overall planning is an important reason for the greening of expressway.

24、 In view of the main problems existing in the greening before the transformation, the Jiangsu Botanical Institute of CAS was invited to make overall plans for the greening of the whole area and put forward the guiding ideology and basic principles of the greening transformation.2.1 guiding ideologyO

25、n the basis of the overall planning, the ecological greening method, with 3 to 5 years to adjust the original green, enrich, enhance road and environment harmony, to restore the natural ecological beauty, give full play to the function of the formation of a variety of greening and environmental prot

26、ection in traffic safety, transportation landscape.2.2 basic principles(1) according to the site conditions, functional requirements and surrounding environmental conditions of each greening monomer, the greening layout should be carried out according to local conditions.(2) according to the differe

27、nt geographical environment and plant ecology and biological characteristics, suitable tree to tree species selection, special attention should be paid to the application of strong adaptability, fast growth of native tree species and the long-term training of the local excellent tree species.(3) thr

28、ough a variety of green means coordination, make up and beautify the road construction damage to the environment and the adverse effects, make highway skillfully with nature, improve the ecological environment along the landscape quality, maintaining ecological balance.(4) the overall composition in

29、 plant ecology theory as the basis, the simulation of natural plant community structure, configuration, the ever-changing landscape in different poses and with different expressions, sections and parts can be used to decorate gimmick rules or abstract, make changes in unity, rich and colorful.3 reco

30、nstruction plan3.1 central divider(1) change the form of planting. The interval 4m planted 1 strains of serotonin as a basic form is still retained, on the basis of embedded bar, with spherical and columnar plants, to form a combination of changes, each unit is 10 15km long.(2) adopt new varieties.

31、The growth of a better method of green transplantation together, the rest of the Qing law gradually eliminated, the more suitable Pittosporum, Euonymus japonicus, Ligustrum quihoui, Berberis thunbergii, Platycladus orientalis ball.(3) the introduction of wild flowers as ground cover. Based on the re

32、tention of white clover, bermudagrass, increase of wild flowers, such as Orychragmusviolaceus, Coreopsis grandiflora, orchids, dwarf, red spider lily and chrysanthemum, patchy planting.(4) increasing low bush flowers. Such as rose, hibiscus, dwarf Canna and hibiscus, Lagerstroemia etc. The adoption

33、of these measures, the formation of antidazzling trees, a variety of forms, the level of scattered, by color film changes, to form a lively and vivid green corridor, rich multicolored decorations.3.2 slopesFor the beautification of cutting slope protection of masonry, stone green plants can climb up

34、 planting to cover or shelter blunt. But there are the following problems: the slope is steep, it is difficult to grow plants; most of them are stony; the soil layer or the soil layer is too thin; the water shortage or artificial irrigation is difficult; the plant adaptability is poor; the survival

35、rate is low. In order to make the slope green, start from the following two steps to start greening and transformation. In order to ensure the thickness of the soil for plant growth and seedling growth needed to maintain the water transformation plan taken in each step of the outer protective layer

36、of 50 60cm high masonry retaining wall, retaining wall backfill in 30 50cm thick soil and other engineering measures; to ensure plant survival, should choose the appropriate seedlings, especially to select drought and barren and species adapt to harsh living conditions, such as pine, arborvitae, tig

37、er, wild rose etc. The reasonable application of engineering measures should be paid attention to in the reform scheme, and the additional load on the top of the step can not be blindly increased so as not to influence the safety of the above slope.3.3 interworkingInterchange is an important part of

38、 the highway, and is the visual center of the occupants. In the greening transformation, we should pay attention to the traffic safety, and make appropriate transformation according to the different geographical and cultural backgrounds. According to the location of the interchange, the whole line c

39、an be exchanged in accordance with the following three types of transformation:(1) suburban type (located in or around the city itself is part of the city). Is the main channel and out of the city, so the greening should be connected with the city landscape style, in highlighting the connotation of

40、the city, according to the requirements of the rules and abstract theme expression patterns (such as the Wuxi exchange with Wuxi plum flower pattern), but the pattern design is not too broken, too miscellaneous, the area is not too big, too you can sketch for foil (such as the East Suzhou interchang

41、e built bridges, pavilions, bridges to create a city atmosphere).(2) pastoral (located in rural areas, far away from the town). The form of afforestation should be based on evacuation and nature, emphasizing coordination with natural scenery and integrating interflow into the wilderness. For large t

42、racts of open space, you can also combine nurseries into a film, planting seedlings, not only can form a certain amount of greening, but also for the future greening of seedlings.(3) the middle type (far away from the big town, but near the small town) is located in the field of farmland, which is t

43、he middle type of suburban and pastoral. In the greening performance, we should take into account the dual nature of suburban and pastoral style, emphasize and highlight their personality, so as to achieve impressive impression.3.4 service areaThe service area is an important scenic spot of the road

44、 landscape, and the greening should be carried out according to the functional requirements of each part. As in the parking lot may be appropriate for planting tall trees, can appropriate segmentation of white cement pavement large parking lot, change the dull atmosphere, but also formed a certain s

45、hade from the sun, so that the vehicle service area; buildings and squares can also through the green garden construction technique of some flower beds, strengthen the aesthetic effect, to create a comfortable and pleasant a lively, leisure environment. At the same time, according to their geographi

46、cal background characteristics, through greening to express, highlighting the local cultural atmosphere, such as plum village service area, that is, planted a lot of trees with Mei word.3.5 reserved lanesThe reserved Lane green is constructed by combination of green plants and simulated natural plan

47、t groups to form artificial vegetation communities. In order to make the highway greening look fresh, rich rhythm and rhythm, near the side of the road with low shrubs, away from the side of the road with a large shrub of different species collocation, composition of a plurality of unit pattern, alternating, repeated, plant height staggered, dense and sparse, there is a closed unit,Ma
