Total length of 152.88 km. The large temperature difference between the four seasons by region, summer heat and humidity, cold and dry winter, the annual average temperature of 15 ℃. Soil is mainly clay, loam, silt, silty soil.
along the highway Through the analysis of ecological and topographical characteristics of proposed green pattern, plant selection and ecological protection measures to enhance highway
one green model
1,UGG boots cheap, the median of the median
glare from the green and induced regulation of view and landscape features. The road used isometric-type plant planted in between the adjacent two evergreen trees, planted about 50 cm single evergreen shrubs, curbs inside, staggered planting flowers. Other mixed-grass seeding bare soil surface, tree, shrub, flower, grass mix, reflecting the sense of hierarchy, to adjust the boring vehicular environment.
2,
embankment slope protection by tree, shrub, flower, grass, rattan combination of the upper slope to consider flowers and evergreen shrubs, mainly, the platform may be appropriate to plant trees, rocky slope of the bottom of the planting code puzzle climbing plants. Ditches on both sides of a row of planted trees (diameter 8 cm), low embankment uniform application of evergreen trees, deciduous high embankment may be appropriate to take into account the fast-growing species. Vetiver grass and soil slope protection available Amorpha fruticosa.
the use of cutting slope, shrubs, flowers, grass, rattan combination to Evergreen-based, matching tree. Opening lines of the arc slope design, reducing the slope to bring the traffic pressure, discomfort. Slope planting with natural style, form different views of the communities, the use of lead, cover, transparent, official cartoon as the way to enrich the landscape along the route.
3, Green
exchange area to meet the transportation function under the premise, combined with the location of each exchange area history, culture and surrounding environment, because of potential themes. Highlight the key species and the local natural and human geographical features of the formation of natural-type plant communities, plant groups, due to increase dominant tree species in size, characteristics of local plant species. Transplantation may also be considered a local tall trees, the formation of exchange signs.
4, roads on both sides of the road green
within the land, drainage ditches on both sides of the tall trees planted to form a vertical direction of the plant landscape. Enclosed space is better, the green volume, improve the ecological environment effect, and for planting willow, fir, camphor, Australia, Acacia, Hibiscus, Cassia corymbosa and other plants.
5, take, dumping sites for construction of green
bound highway along the existing ecological damage, to restore the original ecosystem in the short period of time, can be combined with the surrounding vegetation, Sowing grass seed selection and planting methods Parker pen, but also its original natural appearance, and low cost effective.
6, Service Area Green Green
service area should be considered in all parts of the functional requirements for local conditions. If planted in the parking lot of tall trees may be appropriate to form some greenery, so that vehicles from the exposure. Service Area buildings and squares, garden-style tactics by building flower beds, landscaping to enhance effectiveness, and create a comfortable and pleasant, relaxed and lively casual environment.
Second, the plant application
full account of their ecological characteristics of plants, physiological features, combined with the characteristics of the surrounding environment and highways, landscape plant species with selection following four kinds of situations:
1, the central isolation belt landscape plant selection
central isolation belt highway green green is the key to the design, because here is seriously polluted, shallow and infertile soils, without sufficient moisture, temperature, large temperature changes, poor plant growth environment, so the requirements of plant species also very harsh. selection principle
resistance, pest-resistant and strong, easy to plant, easy to survive, easy to trim, quick, self-pollution, and does not affect traffic safety. They should also change according to seasonal plants, choose colorful, graceful person.
selected plant trees: T Park; Shrubs: Nandina domestica, Hypericum, Pyracantha, Pittosporum ball; to be, and border plants: Phlox subulata, Ophiopogon, Zephyranthes, tortoiseshell holly.
2, slope landscape plant selection
green slope Slope Stability main purpose is to prevent erosion.
selection criteria to select the cold, drought, high temperature, anti-pollution, pests and diseases, easy to grow, Low, developed root system, coverage is good, easy to survive, easy management, taking into account the effects of herbs or woody landscape plants.
Slope selection of plants, selection of conifers, black locust, wild chrysanthemum, Coreopsis, leaf privet, heather, Vitex, oak thorn, camphor, sarsaparilla, thinking child, the white-backed leaves, constitutive bone, mountain trail, Oak, Pittosporum, cloud reality, mountain pepper, bermudagrass, white clover, tall fescue. Grass and tree, shrub Hunzai, with short-acting and long-lasting, tall fescue, bermudagrass, white clover mixture, air-based matching, dense growth, in Slope, to prevent the erosion effect is obvious, but it should be noted that control of grasses the ratio between. After the decline of grass, shrubs grew up, loose, Bo Changshou, drought-resistant infertile, evergreen, landscape features than the lawn. Their relatively poor condition of the slope, growing pine is not good, do not worry pine, cypress grow too high and the situation there turned baskets. Tree, shrub and grass Hunzai slope, the highway should be innovative green mode.
embankment, the choice of Bermuda grass, white clover, and more Mulan, alfalfa, lespedeza, Amorpha fruticosa, vetiver. Vetiver root system, were two deep meters, perennial, resistant to poor, acid, alkali and metal pollution in case of long-term survival of drought or waterlogging,UGG shoes, strict requirements on the soil,UGG boots, growing robust, and strong self-sowing reproduction . Slope Stability with vetiver, low cost, the Hubei Highway Greening is innovation.
3, Interchange Landscape plant selection
green generally larger interchange, and climatic conditions and elsewhere is significantly better than small, in the plant selection is not exactly the same as the other lots. With Yue Freeway Interchange of 8, the formation of the landscape not only adds a highway in view, while increasing economic efficiency, improve the regional standard of living. Principle of selection for the return fast, good quality, resistance,UGG boots clearanc, easy management, and easy maintenance of the plants. The selected plants tallow tree, Koelreuteria paniculata, myrobalan plum, Pyracantha, azalea, red flowers, ginkgo, Liriodendron chinense, oleander, Pittosporum, slash pine, Ligustrum, weeping willow and so on. Many times planting flowers and small crown patch of white clover as a ground cover, evergreen, and seeding flower seeds, three quarters of flowering.
4, service area, office and living areas Landscape plant selection
selection principle Plants resist strong, easy to plant, easy to survive, easy to trim, easy management, variety selection , graceful person, not only beautify, but also incense, color technology.
selected plant Metasequoia glyptostroboides, Qingtong, osmanthus, just bamboo, camellia, camphor, loquat, magnolia, Koelreuteria paniculata, Hibiscus, Lagerstroemia, myrobalan plum, red flowers, golden privet, pistache, etc. .
