In the modern high-rise building of social environment, natural green space is what people wanted. Vertical greening application in the urban landscape, on the vision increased urban landscape view and admire a gender, improved the city green landscape, ecological improves the heat island effect. Vertical greening make a considerable contribution to urban landscape.
Vertical greening refers to the geographical conditions, artificial banyan trees make full use of the different choice of climbing plants and other plants, attachment or laying on the various structures and other spatial structure of green way.
Vertical greening are widely used in the city, vertical greening can be divided into large, medium and small scale (according to the greening coverage and accessibility of crowd into mass: large green area accessibility is weak; Medium size: accessibility of green area big man is strong; Small: small green area of strong accessibility), from the perspective of three examples to analyze the planting ways of vertical greening and its plant configuration points. A large scale.
Large area of green area, low close human nature, is a large area of whole city greening. Mainly divided into the following two Spaces.
1.1 slope protection and platform greening.
Slope protection is to prevent the slope built washed, from the fake ficus tree function can be divided into two kinds: one kind is built for ordinary gentle slope concrete slope protection, lattice frame vegetation slope protection and vegetation slope protection, etc., this kind of slope protection is relatively easy to afforest, herb and shrub plants, can be planted windbreak and sand-fixation of greening effect. Another is to provide a steep rock slope sliding resistance of masonry retaining wall, gravity retaining wall, lean on a wall, retaining wall, cantilever retaining wall, retaining wall, anchor retaining wall, etc. This kind of slope protection because of the steep slope, not suitable for growing plants, lead to a large area of wire mesh in the surface of the lack of energy or concrete. For this kind of slope protection, can be used to climb, vertical virescence plant type or twining vines climbing, form the three-dimensional landscape greening. Around the set-up for landscape corridor, such as land planted vines, also can be planted in the side of the wall, bracket or wire, ropes and tools as traction, make the climbing plants form vertical greening on the wall.
Terraced terrain can be seen everywhere in the chongqing's unique faux ficus tree topography, south bridgehead greening and the stone slope greening of jialing river bridge are depending on the type of site platform using integrated stereo virescence, shrubbery, rattan platform plane planting trees, shrubs, edge planted vines, in accordance with the growth of retaining wall, trees, shrubs, vines, three plants reasonable collocation, build green ecological terraced landscape.
1.2 the viaduct afforestation.
Viaduct is indispensable to modern city traffic types, going back large ficus tree and forth across the reinforced concrete in the urban space, at the same time of the transportation is convenient, also have brought more gray space and gray visual feeling. Viaduct of chongqing light rail column with climbing vertical virescence environment greening, mainly adopts the ivy, growth ability, evergreen, has certain ornamental value, very suitable for road greening.
2 dimensions.
Medium-sized green area is relatively small, sex is strong, high contact resistance. Need the vertical greening space can be divided into the following two categories.
2.1 the road greening.
