This paper takes nanjing riverside avenue greening landscape design as an example, from the greening landscape of the flat and composition, color composition, three-dimensional composition of the three aspects of this program is analyzed, discusses the characteristics of the landscape composition of nanjing city road, and in this regard, argues that nanjing road greening through these three composition of organic combination in order to make it play the maximum landscape benefit. In this regard, it is argued that the greening of roads in Nanjing should be organic through these three major compositions in order to maximize the landscape benefits.
Compared with other urban landscaping landscape, road greening landscape design is the most frequent contact with local residents or foreign visitors, forming the most profound and lasting impression of a green landscape type, to shape the urban landscape features to improve the city's visibility are very important role.
Nanjing as one of the four great furnaces, the composition of the road green landscape has more important significance than other cities. Through the road landscape design, efforts to create a green environment surrounded by trees in summer, winter sunshine. The following is an example of Nanjing Riverside Avenue green landscape design from the plane composition, color composition, three-dimensional composition of Nanjing road green landscape composition.
1, the status quo analysis
Nanjing riverfront avenue is a landscape boulevard of the riverfront characteristics of the city of nanjing, the planning of 15.5 kilometers of the riverfront avenue north of Sanchahe Bridge, south to the Yangtze River three bridge Tianhou village interchanges, the design of the two-way 8-lane, * * * divided into three phases of construction. Which is located in the first phase of the Weijiu Road to Weijiu Road, between 3.6 kilometers long; the second phase of the Weijiu Road has been north to Sanchahe, *** 4.9 kilometers; the third phase is located in the southernmost, the distance is also the longest, from the Weijiu Road to the Yangtze River Bridge stretches for 7 kilometers. Riverside Avenue strings Dinghuaimen Street, Caochangmen Street, Hanzhongmen Street and other major east-west arteries, which also builds up the traffic skeleton of the west side of the river. The two main fast lanes in the old city and new area, i.e. the old west main road and the soon-to-be-completed Riverside Avenue, will form a ring road around the new city and realize the fast docking of the old city and new area. Riverside Avenue has a width of up to 60 meters and 8 lanes in both directions. Because it is designed for motor vehicles, there are no sidewalks or slow lanes along its 15.5 kilometer length. Riverside Avenue is also part of the city's rapid arterial roads, the entire line will be erected 5 overpasses. In order not to destroy the riverside park and the Olympic Sports Center of the central axis, Riverside Avenue in the Weihua Road to the Qingshi ridge section also set up a 958-meter underpass.
Nanjing Riverside Avenue is located in the riverside area of Nanjing Hexi, is an important north-south urban expressway in the new city center of Hexi, and is also an important part of the riverside landscape belt in the new city center. This project is the design of the road greening landscape of the 2.4 standard B section, 3.1 standard, 3.2 standard, 3.3 standard of the Riverside Avenue, which is an important project to enhance the image of the Riverside Avenue and show the characteristics of the modernized riverside city of Nanjing.
Planning and design **** there are four principles:
1. The whole line of green landscape unity in the changes, coordinated arrangement of the sections, so that the style of unity and rich, and has been built in the southern section to coordinate.
2. The style of greening landscape should be a combination of atmosphere and sophistication. Green planting style should be neat, majestic, have momentum, only suitable for the speed of 80 kilometers / hour line of sight requirements, but also in line with the style of the city of Nanjing, in the main intersection of the place, to carefully create beautiful plant landscape, reflecting the exquisite.
3. To solve the problem of the slope of the central divider according to the local conditions, to avoid the shortcomings and to take advantage of the advantages.
4. Take into account the safety, ecological benefits and sustainable development. Full consideration of traffic safety, anti-glare planting, evergreen trees as the backbone species, mainly trees, give full play to the ecological benefits of road greening and landscape benefits.
First of all, a site visit to the Riverside Avenue, the road status quo is 20 meters wide, the status quo of the green belt grows well, the road traffic is smooth, both sides of the design of the landscape belt in the changes in the search for unity. As an important part of the Nanjing city traffic fast road network, Nanjing Riverside Avenue 3.5 kilometers long weiqi road to wei jiu road section and synchronization of the construction of the riverside scenic belt a demonstration section of the project has been completed in October 2006 before. For the west of the river area to add a blend of transportation, landscaping, tourism and leisure and other functions as one of the modern ecological landscape avenue. The riverfront boulevard will be connected with the riverfront scenic belt to form an overall landscape effect. In order not to affect the Olympic Sports Center to the riverbank of the overall landscape style, the north-south Riverside Avenue tunnel program through the Olympic Sports Center to the river's east-west axis, the length of the 400-meter bidirectional sunken tunnel is currently more than half of the civil engineering work is completed, the top of the tunnel will be used as a landscaped reserved space, play the role of the Olympic Park and the traffic connection between the riverside scenic area.
The Riverside Boulevard Scenic Byway is designed by the world-renowned Australian cox company, with reference to the experience of Shanghai and other places in the construction of urban green space. At present, the construction of the first phase of the demonstration section is 3.5 kilometers long, covering an area of about 2,000 acres, along an internal river linking a series of ecological, recreational, landscape commercial business projects, according to the plan is divided into three parts of the activity area, recreation area and ecological area, the activity area will be open to the public activities, set up catering and entertainment, touring and performance facilities. The leisure area will open up a riverside wetland park, equipped with a high-grade hotel, creating a leisure place in harmony with the natural environment. The ecological zone will focus on natural vegetation, forming a quiet and elegant ecological landscape.
2, road green landscape design analysis
2.l green landscape plan composition
Plane composition is the basis of the design of the cut, and the point, line, but the basic elements of the composition. In the green landscape design is also so.
The plane design of the green landscape in the riverside boulevard also fully embodies the three elements of plane composition. The whole green belt for a long and narrow green avenue, the use of rich changes in the shape of the "8" will be a perfect division of the green belt, the formation of the foreground layer and the background layer of the two parts. The "8" shaped ribbon as the dividing part constitutes a major element of the "line" in the planar composition. In front of the ribbon, i.e. in front of the green belt, the ground cover lawn is planted at equal intervals, which enhances the unity of the entire road greening. In the back of the ribbon, that is, the background layer of the ribbon, isometric planting camphor, heather and other trees, under which planted flowering ivy ground cover, forming a tree intensive planting and the formation of large color block effect, which is a new form of road green landscape design in the past two years. The simple shape of the tree array effect constitutes the element of "surface" in this planar composition. The perfect use of the landscape stone constitutes the "point" element of this plan composition.
Because of the organic combination of the three elements of points, lines, surfaces, making the entire Riverside Avenue road greening design is balanced and rich ten changes, emphasizing the large color blocks, large lines, patterns simple and bright, strong contrast, forming a good visual landscape effect.
2.2 Green landscape color composition
Color is an important element of the world's rich and colorful, but also one of the important factors that determine the good and bad of all design, a good design work is inseparable from the matching of harmonious colors. In green landscape design, color composition is specifically expressed as the color change of plants and the seasonal change of green landscape. In the green landscape green is the main body of color, the basic materials used in the design of most of the green, so to make the green landscape presents a colorful color levels, plant varieties with especially important. Good plant configuration design can make the original plate of greens green belt landscape become four seasons, a mountain flower.
In the Riverside Boulevard green landscape design also used to the principle of color composition, focusing on plant varieties of reasonable collocation, taking into account the seasonal landscape of the plant landscape. In the "8" shaped ribbon in the brightly colored boxwood and redbud with together, and redbud in the winter will still leave a trace of color, for the winter of the Riverside Boulevard landscape brought a piece of spring color, planted in front of the ribbon point of redbud leaves deep red, spring and autumn seasons to open pink flowers, in the neatly pruned cypress ribbon under the backdrop of the more colorful. Ribbon after the camphor and other trees, alternating with each other, forming a color contrast between light and dark evergreen and deciduous mixed arrangement, enriching the entire green corridor of the seasonal landscape, reflecting the design of the perfect color composition.
2.3 Three-dimensional composition of the green landscape
A good design work in addition to excellent flat and color composition, but also can not be separated from the level of rich three-dimensional composition. Good three-dimensional composition makes the riverside boulevard green belt landscape is rich in strong display charm. In the riverside avenue greening landscape design elevation composition, in order to coordinate the plant landscape in the three-dimensional structure of the unity and relevance, in addition to trees, shrubs, ground cover plants to form a multi-layer structure, but also pay attention to the selection of different plant modeling, such as triangular red jacaranda ball, the natural stretch of the octagonal gold plate, the gesture of the excellent off the purple leaf plum and so on. The height of different plants, constituting moderate changes in the landscape line, enriching the green belt green landscape facade landscape.
3, conclusion
Through the above discussion of the three aspects of the green landscape design of Nanjing Riverside Avenue, we can see that in the actual landscape design process, should pay attention to the plane composition, color composition, three-dimensional composition of the three elements of the composition of the organic combination, in order to create a novel, chic road green landscape.
Nanjing around the highway will become "city road"------------
Reporters yesterday from the Nanjing around the highway site was informed that a total length of 41.323 kilometers of the Nanjing around the highway southeast section will be closed at the end of April next year, by the end of this year around the highway pavement foundation project will be realized through, the overall project will be the first to be completed. The project will be realized through, the overall project will be opened to traffic in 2010.
According to Xiong Qiang, project manager of the CCCC First Public Bureau, the southeast section of the Nanjing Bypass Expressway is different from the outbound expressways such as Ning-Hangzhou, Ning-Huai-Huai and Shanghai-Nanjing, and it passes through the south and east of the city, and the whole line*** intersects with 4 national highways, 5 provincial highways and 11 urban roads, and crosses the railroads for 4 times, and the southeast ring of the Bypass Expressway is located in the Yangtze River Third Bridge and the Yangtze River Fourth Bridge which is under construction. Between the three bridges over the Yangtze River and the four bridges over the Yangtze River under construction, it is an important hub for the traffic in and out of the Jiangnan area, the transit traffic and the inter-city traffic, and it is a fast channel in the periphery of the city of Nanjing as well as an integral part of the trunk line of the national highway Hurong in the national planning. After the completion of the two-way 6 lanes around the highway and Shanghai-Nanjing Expressway, Ning-Hangzhou Expressway, Airport Expressway and Ningma Expressway have built interconnections, foreign vehicles can be convenient and fast through the bypass swept through the destination of Nanjing, without the need to enter the city of Nanjing again, according to the planning of the southeastern section of the starting point of the Yangtze River Bridge to the Shanghai-Nanjing Expressway main entrance, the driving time required is only half an hour or so.
It is understood that around the southeast section of the whole line **** set up eight interchanges, respectively, with Ningwu Highway, around the city high-speed connected to the Liu Village Interchange; docking with Ningdan Road, Dongshanqiao Interchange; docking with the airport high-speed Nanzhuang Interchange (near the village of Dongjian); with the 102 National Highway, Ning Li Highway, connected to the Yinxiang Interchange; with the Tianyuan Road, the science park interchange; and the streets of the Dongshan connected to the Dongshan Interchange, Ninghang Interchange connected with Ninghang Expressway and Kirin Interchange that strings together Huning Expressway. Driving on the Bypass Expressway, there is an average of about 5 kilometers of interchanges, from which you can easily enter and exit the main city of Nanjing.
Feng Baochun, chairman of Nanjing Transportation Group, said that after the completion and opening of the southeast section of the bypass in 2010, the biggest impact on the traffic pattern of Nanjing is to ease the pressure on the flow of highway around the city. In recent years, with the continuous expansion of Nanjing city, the function of the bypass highway is gradually from the peripheral line into the "city road".
Nomenclature:
What is the bypass highway
The bypass highway is the city's "first ring", while the bypass highway is the future Nanjing's "second ring". Around the highway, the entire line of preliminary planning through Xianlin - Shibuqiao Highway Bridge - Yong six high-speed - Dafang - Ninghuai high-speed - Laoshan - Yangtze River Bridge - Jiangning -Xianlin and other places, in a closed loop. The southeastern section of the Bypass Highway is the *** line section of the main national highway, national key trunk highway and national and provincial trunk highway transit traffic through Nanjing. The reason why the highway is called the "second ring" is because it has to cross the airport highway, Shanghai-Nanjing Expressway and other roads, and finally realize the ring around Nanjing.
Bypass Highway boosts Nanjing's development ------------
News Alert: The southeast section of the Bypass Highway is located between the Third Yangtze River Bridge and the Fourth Yangtze River Bridge under construction, with a total length of 41 kilometers, and is an important hub for access traffic, transit traffic and inter-city traffic in the south of the Yangtze River region, and is also the city's largest independent investment in the construction of the largest total amount of construction so far, the longest mileage of the highway. September 20, 2006, Nanjing Municipal Transportation Group registered the establishment of Nanjing around the southeast section of the Expressway Limited Liability Company, responsible for the construction of the project, around the southeast section of the Expressway December 30, 2006 held a groundbreaking ceremony, October 2007 substantial start of construction, has now completed 50% of the roadbed bridge project, is scheduled to be completed within the year 70% of the roadbed bridge project, and strive to be completed in 2010 to open to traffic. Strive to be opened to traffic in 2010.
With Ning-Hangzhou, Ning-Huai, Shanghai-Nanjing and other outbound expressway is different, around the southeast section of the expressway for the Nanjing territory of the highway, which passes through the southern and eastern part of the city, the whole line *** and 4 national highways, 5 provincial highways and 11 city roads, 4 times across the railroad, and in the process of construction need to relocate a large number of high and low-voltage power lines, communication lines, gas pipelines, water pipes, aviation oil pipelines and other pipelines. A variety of pipelines. In addition, around the southeast section of the highway along the line may also touch the various dynasties of cultural relics and burial sites, construction conditions are complex, the construction difficulty is called the most in the history of Nanjing highway construction.
Bypass Expressway to be opened to traffic in 2010
"The construction of the southeastern section of the Bypass Expressway, despite the difficulties, has been progressing smoothly with the care and support of all sectors of the community, and we will strive to have it opened to traffic in 2010." Zhang Yingfang, deputy general manager of the city's transportation group, said.
It is reported that around the southeast section of the highway is the city's "five bridges and two tunnels, two rings, two horizontal twelve shot" in the external transportation layout "two rings of high-speed" of the important components of the road, is through the city's Shanghai and Rongzhou National Highway main highway, the national key trunk highway and the national provincial trunk highway transit traffic. National and provincial trunk highway transit traffic *** line section. After its completion, and the Shanghai-Nanjing Expressway, Ning-Hangzhou Expressway, Airport Expressway and the Ningma Expressway are built with interconnections, foreign vehicles can easily and quickly through the bypass swept through Nanjing straight to their destinations, without the need to enter the Nanjing urban areas around, from the southeast section of the highway around the starting point of the Yangtze River Bridge to the Shanghai-Nanjing Expressway main entrance, the driving time required is only half an hour or so.
In order to maximize the performance of this expressway, eight interchanges have been set up along the entire route***, namely, the Liu Village Interchange connected with the Ningma Highway and the Bypass Highway; the Dongshanqiao Interchange connected with the Ningdan Highway; the Nanzhuang Interchange connected with the Airport Expressway (near the Dongjian Village); the Yinxiang Interchange connected with the Shuanglong Highway; the Science Park Interchange connected with Tianyuan Highway; the Dongshan Interchange connected with Dongshan Street; and the Dongshan Interchange connected with Old Ningxia Highway. Dongshan Interchange, Ninghang Interchange connected with the old Ninghang Road, and Kirin Interchange that strings together the Huning Expressway. Driving on the Bypass Expressway, there is an average of about 5 kilometers of interchanges and entrances, from which you can easily enter and exit the main city of Nanjing.
Transportation experts said, around the southeast section of the highway was completed in 2010 after the opening of the traffic pattern of Nanjing City, the biggest impact should be to ease the flow of highway pressure around the city. Nanjing around the city highway was built, has been responsible for the function of the peripheral ring road, most of the transit freight vehicles are traveling on this road, these two years, with the continuous expansion of the urban area of Nanjing, in particular, since the Jiangning District into Nanjing, around the city highway function is gradually from the peripheral ring road into the city of the road, the southeast section of the highway is completed around the Vietnam After the completion of the southeastern section of the bypass highway, it is possible to liberate the bypass highway to become the "city road".
