Taking the greening landscape design of Nanjing Binjiang Avenue as an example, this paper analyzes the scheme from three aspects: plane composition, color composition and three-dimensional composition of greening landscape, probes into the characteristics of Nanjing urban road landscape composition, and demonstrates that Nanjing urban road greening can exert its maximum landscape benefit only through the organic combination of these three components.
Compared with other urban landscape, road greening landscape design is the most frequent and longest-lasting greening landscape type for local residents and foreign tourists, which plays a very important role in shaping urban landscape characteristics and improving urban visibility.
Nanjing is one of the four furnaces, and the composition of road greening landscape is more important than other cities. Through road landscape design, we will strive to create a green environment surrounded by green trees in summer and sunny in winter. Taking the greening landscape design of Nanjing Binjiang Avenue as an example, this paper expounds the composition of Nanjing road greening landscape from three aspects: plane composition, color composition and three-dimensional composition.
1, current situation analysis
Nanjing Riverside Avenue is a landscape avenue with the characteristics of Nanjing urban riverside. The planned total length of Binjiang Avenue is 15.5km, starting from Sanchahe Bridge in the north and reaching Tianhou Village Interchange of the Third Yangtze River Bridge in the south. Designed as two-way eight lanes, it will be built in three phases. The first phase is located between Weijiu Road and Weiqi Road, with a length of 3.6 kilometers; The second phase extends from Weiqi Road to Sancha River, with a distance of * * * 4.9 kilometers; The third phase is located at the southernmost tip and the farthest distance, stretching for 7 kilometers from Weijiu Road to the Third Yangtze River Bridge. The main east-west trunk lines such as Dinghuaimen Street, Caochangmen Street and Hanzhongmen Street are strung together on Binjiang Avenue, which also constructs the traffic skeleton in Hexi area. The two main expressways in the new area of the old city, namely the west trunk road of the old city and the riverside avenue to be built soon, will form a loop around the new city to realize the rapid docking of the new area of the old city. Binhe Road is 60 meters wide and has 8 lanes in both directions. Because it is specially designed for motor vehicles, there are no sidewalks and slow lanes within the length of 15.5 km. Binjiang Avenue is also an integral part of the urban expressway, and five overpasses will be erected along the whole line. In order not to destroy the central axis between Binjiang Park and the Olympic Sports Center, a 958-meter underpass tunnel was set when Binjiang Avenue crossed the section from Wei Ba Road to Qingshigeng.
Nanjing Binjiang Avenue is located in the riverside area of Hexi, Nanjing. It is an important urban expressway in the north-south direction of Hexi New Town and an important part of the riverside landscape belt of the new town. This project is the road greening landscape design of section B, section 3. 1, section 3.2 and section 3.3 of bid 2.4 of Binjiang Avenue, and it is an important project to enhance the image of Binjiang Avenue and show the characteristics of Nanjing modern riverside city.
There are four principles in planning and design:
1. The greening landscape of the whole line has changed uniformly. Coordinate and arrange each bid section to make its style unified and rich, and coordinate with the completed southern section.
2. The style of greening landscape should be combined with atmosphere and exquisiteness. The planting style of greening should be neat, vigorous and imposing, so as to meet the requirements of 80km/h driving sight and conform to the style of Nanjing city. At the main intersection, we should carefully create a beautiful plant landscape, reflecting exquisiteness.
3. Solve the slope problem of the central separation zone according to local conditions, develop strengths and avoid weaknesses, and give play to advantages.
4. Give consideration to safety, ecological benefits and sustainable development. Fully consider traffic safety, anti-glare planting, take evergreen tree species as the backbone tree species, and give full play to the ecological and landscape benefits of road greening.
First, we made a field trip to Binjiang Avenue. The road is 20 meters wide, the green belt grows well, the road traffic is smooth, and the design of landscape belts on both sides seeks unity in the change. As an important part of Nanjing urban traffic expressway network, the 3.5-kilometer section from Weiqi Road to Weijiu Road of Nanjing Binjiang Avenue and the first-phase demonstration section of Binjiang Scenic Belt under simultaneous construction were completed before June 65438+ 10, 2006. Add a modern ecological landscape avenue integrating transportation, garden landscape, tourism and leisure for Hexi area. Binjiang Avenue will be integrated with the riverside scenery belt to form an overall landscape effect. In order not to affect the overall landscape from the Olympic Sports Center to the river bank, the North-South Riverside Avenue adopts the tunnel scheme to cross the east-west axis from the Olympic Sports Center to the river bank. At present, more than half of the civil works of the 400-meter two-way sinking tunnel have been completed, and the top of the tunnel will be used as a reserved space for landscape, which will play a role in the traffic connection between the Olympic Sports Park and the riverside scenery belt.
The landscape belt of Binjiang Avenue was designed by the world-famous Australian cox company, with reference to the experience of urban green space construction in Shanghai and other places. The first-phase demonstration section under construction is 3.5 kilometers long and covers an area of about 2000 mu. A series of ecological, leisure and landscape commercial projects are connected in series along an internal river. According to the plan, it is divided into activity area, leisure area and ecological area. The activity area will be dominated by open public activities, with facilities such as catering, entertainment and sightseeing performances. The leisure area will open up a riverside wetland park, equipped with high-end hotels, and create a leisure place in harmony with the natural environment. The ecological zone will be dominated by natural vegetation, forming an elegant and quiet ecological landscape.
2. Analysis of road greening landscape design
2. The plane composition of green landscape
Plane composition is the basis of tangent design, and points and lines are the basic elements of plane composition. So is the green landscape design.
These three plane elements are also fully reflected in the plane design of the green landscape of Binjiang Avenue. The whole green belt is a long and narrow green avenue, which is perfectly divided by the ever-changing "8" shape to form two parts: the foreground layer and the background layer. This 8-shaped ribbon, as a division, constitutes a main element "line" in the plane composition. The lawn is planted in front of the belt, that is, in front of the green belt, which increases the unity of the whole road greening. Behind the belt, that is, the background layer of the belt, trees such as Cinnamomum camphora and heather are planted at equal intervals, and ivy ground cover is planted below, forming a large color block effect formed by dense planting of trees, which is a new form of road greening landscape design in recent two years. This simple tree array effect constitutes the element of "face" in this plane composition. The perfect use of landscape stones constitutes the "point" element of this plane.
Due to the organic combination of point, line and surface, the whole road greening design of Binjiang Avenue is balanced and diverse, emphasizing large color blocks and lines, with simple and bright patterns and strong contrast, forming a good visual landscape effect.
2.2 color composition of green landscape
Color is a rich and diverse important element in the world, and it is also one of the important factors that determine all design quality. Good design works are inseparable from harmonious colors. In the design of green landscape, color composition is reflected in the color change of plants and the seasonal change of green landscape. In the greening landscape, green is the main color, and the basic materials used for design are mostly green, so in order to make the greening landscape present rich and colorful color levels, the collocation of plant varieties is particularly important. Good plant configuration design can make the original green belt landscape of a dish more beautiful in four seasons and become a beautiful mountain flower.
The greening landscape design of Binjiang Avenue also applies the principle of color composition, paying attention to the reasonable collocation of plant varieties and taking into account the seasonal landscape of plant landscape. In the "8"-shaped ribbon, the bright boxwood in Phnom Penh is matched with the safflower following wood, which will still have a trace of color in winter, bringing a touch of spring to the riverside avenue landscape belt in winter. The red-followed wood ball planted in front of the ribbon has dark red leaves and pink flowers in spring and autumn, which is more gorgeous against the trimmed dragon and cypress ribbon. Trees such as Cinnamomum camphora behind the ribbon alternate with each other, forming a mixed arrangement of evergreen and deciduous leaves, which enriches the seasonal landscape of the whole green corridor and reflects the perfect color composition in the design.
2.3 the three-dimensional composition of green landscape
A good design work not only needs excellent plane composition and color composition, but also needs rich three-dimensional composition. The good three-dimensional composition makes the green belt landscape of Binjiang Avenue full of strong display charm. In the vertical composition of the greening landscape design of Binjiang Avenue, in order to coordinate the unity and relevance of the plant landscape in the three-dimensional structure, in addition to the multi-layer structure formed by trees, shrubs and ground cover plants, attention is also paid to different plant shapes, such as triangular red flowers following wooden balls, naturally stretched octagonal gold plates, and purple plums with excellent posture. The heights of different plants constitute a landscape line with moderate changes, which enriches the facade landscape of green belt landscape.
3. Concluding remarks
Through the above discussion on the greening landscape design of Nanjing Binjiang Avenue, we can see that in the actual landscape design process, we should pay attention to the organic combination of plane composition, color composition and three-dimensional composition, so as to create a novel and unique road greening landscape.
Nanjing will bypass the expressway and become an "urban road".
The reporter learned from the scene of Nanjing Ring Expressway yesterday that the southeast section of Nanjing Ring Expressway with a total length of 4 1.323km will be closed at the end of April next year, and the pavement foundation project of Nanjing Ring Expressway will be completed by the end of this year, and the whole line will be opened to traffic in 20 10.
According to Xiong Qiang, the project manager of No.3 Public Security Bureau of CCCC, unlike Ning Hang, Ninghuai and Shanghai-Nanjing, the southeast section of the bypass expressway is an expressway in Nanjing, passing through the south and east of the city. The whole line * * * intersects with four national highways, five provincial highways and 1 1 urban roads, crosses the railway for four times, bypasses the southeast ring of the expressway, and is located in the third Yangtze River Bridge and the Yangtze River under construction. After the completion, the two-way six-lane bypass expressway is connected with Shanghai-Nanjing Expressway, Nanjing-Hangzhou Expressway, Airport Expressway and Ningma Expressway, so that passing vehicles from other places can bypass Nanjing to their destinations conveniently and quickly without entering Nanjing urban area again. According to the plan, it only takes about half an hour's drive from the third Yangtze River Bridge in the southeast section to the entrance of the main line of Shanghai-Nanjing Expressway.
It is understood that there are eight interchanges around the southeastern section of Vietnam, namely Liucun Interchange connected with Ningwu Highway and Ring Expressway; Dongshan Bridge connects Ningdan Road; Nanzhuang Interchange (near Dong Jian Village) connected with the airport expressway; Intersection of India and National Highway 102 and Li Ning Highway; Interchange with Tianyuan Road Science Park; Dongshan Interchange connected with Dongshan Street, Ning Hang Interchange connected with Nanjing-Hangzhou Expressway and Qilin Interchange connected with Shanghai-Nanjing Expressway drive around the expressway, and there is an interchange entrance about 5 kilometers on average, from which you can easily get in and out of the main city of Nanjing.
Feng Baochun, chairman of Nanjing Transportation Group, said that after the completion and opening of 20 10, the biggest impact on Nanjing's traffic pattern was to ease the traffic pressure on the ring expressway. In recent years, with the continuous expansion of Nanjing's urban area, the function of bypass roads is gradually changing from peripheral lines to "urban roads".
Noun explanation:
What is a detour?
The ring road is the "first ring" of the city, and the ring road is the "second ring" of Nanjing in the future. Around the highway, the whole line is preliminarily planned to pass through Xianlin-Shibuqiao Highway Bridge-Liu Yong Expressway-Dachang-Ninghuai Expressway-Laoshan-Third Yangtze River Bridge-Jiangning-Xianlin and other places in a closed ring. The southeast section of the bypass highway is the national and provincial trunk highways, national key trunk highways and national and provincial trunk highways that pass through Nanjing. The bypass road is called the "Second Ring Road" because it needs to fly over many roads such as Airport Expressway and Shanghai-Nanjing Expressway, and finally realize the circumnavigation of Nanjing City.
Bypassing the Vietnam Expressway to Boost Nanjing's Development-
News Tip: The southeast section of the bypass expressway is located between the third Yangtze River Bridge and the fourth Yangtze River Bridge under construction, with a total length of 4 1 km. It is an important access, transit and intercity transportation hub in Jiangnan area, and it is also the expressway with the largest total investment and the longest mileage in our city so far. On September 20, 2006, Nanjing Communications Group registered and established Nanjing Ring Expressway Southeast Section Co., Ltd., which was responsible for the project construction. The groundbreaking ceremony of the southeast section of the bypass expressway was held on February 30, 2006, and the construction started substantially in June 2007. At present, 50% of subgrade and bridge projects have been completed, and 70% of subgrade and bridge projects are planned to be completed this year, striving for 2007.
Different from Ning Hang, Ninghuai and Shanghai-Nanjing exit expressways, the southeast section of Bypass Expressway is an expressway in Nanjing, which passes through the south and east of the city, intersects with four national highways, five provincial highways and 1 1 urban roads, and crosses the railway four times. In the process of construction, a large number of high and low voltage power lines, communication lines, gas pipelines, water pipelines, jet fuel, etc. need to be relocated. In addition, around the southeast section of the expressway, cultural relics and tombs of various dynasties may be touched, and the construction conditions are complex, and the construction difficulty is the highest in the history of Nanjing expressway construction.
Bypass the expressway 20 10 and open to traffic.
"Although it is difficult to bypass the southeast section of the expressway, with the care and support of all walks of life, the overall progress is relatively smooth, and we strive to complete the 20 10." Zhang said, deputy general manager of the Municipal Transportation Group.
It is reported that bypassing the southeast section of the expressway is an important part of the "Second Ring Expressway" in the external traffic layout of "Five Bridges and Two Tunnels, Two Rings, Two Horizons and Twelve Shoots" in our city, and it is also the * * * section of the transit traffic of Shanghai-Chengdu national trunk road, national key trunk roads and national and provincial trunk roads. After completion, it will be connected with Shanghai-Nanjing Expressway, Nanjing-Hangzhou Expressway, Airport Expressway and Ningma Expressway, so that passing vehicles from other places can conveniently and quickly bypass Nanjing and reach their destinations without entering Nanjing again. It only takes about half an hour's drive from the Third Yangtze River Bridge, the starting point of the southeast section of the Ring Expressway, to the entrance of the main line of the Shanghai-Nanjing Expressway.
In order to give full play to the function of this expressway, eight interchanges have been set up, namely Liucun Interchange, which is connected with Ma Ning Highway and Ring Highway. Dongshan Bridge connects Ningdan Road; Nanzhuang Interchange (near Dong Jian Village) connected with the airport expressway; Yinxiang Interchange is connected with Shuanglong Avenue; Science Park Interchange connected with Tianyuan Road; Dongshan Interchange connected with Dongshan Street, Ning Hang Interchange connected with Old Ning Hang Road, and Qilin Interchange connected with Shanghai-Nanjing Expressway drive on the bypass expressway, with an average of about 5 kilometers and an interchange entrance, from which you can easily enter and leave the main city of Nanjing.
According to traffic experts, after the completion and opening to traffic of the southeast section of the 20 10 bypass expressway, the biggest impact on Nanjing's traffic pattern should be to ease the traffic pressure of the bypass expressway. After the completion of Nanjing Ring Road, it has been assuming the function of the outer ring road, and most transit freight vehicles are driving on this road. In the past two years, with the continuous expansion of Nanjing city scale, especially since Jiangning District was merged into Nanjing, the function of the ring road has gradually changed from the outer ring road to the "inner city road". After the completion of the southeast section of the ring road, the ring road can be completely liberated into an "inner city road".
