Three-dimensional greening, the functions you don’t know!

Three-dimensional greening is the most ideal way to improve urban greening coverage, save land, and open up new space for urban greening. If a city truly realizes three-dimensional greening, its green coverage will increase exponentially, and the entire city's ecosystem will be greatly improved. The following is a detailed introduction to the functions and benefits of three-dimensional greening.

Function 1 of three-dimensional greening: improving the ecological environment

Green plants can use light energy to produce oxygen; fix carbon dioxide and synthesize organic matter. According to measurements, each hectare of forest green plants can absorb a fixed 1050 and 900 kilograms of carbon dioxide per day respectively. Green plants can release 32g of oxygen for every 44g of carbon dioxide they absorb. During the growing season, one hectare of broad-leaved forest absorbs 900kg of carbon dioxide and releases 600kg of oxygen a day. In this way, green plants play a role in maintaining the balance of carbon dioxide and oxygen in the atmosphere, absorbing carbon dioxide, releasing oxygen, completing gas renewal, and continuously providing oxygen to aerobic organisms. On green streets, the dust content in the air is 56.7% lower than in areas without greenery; the amount of dust above grass is only 1/6 to 1/3 of that on bare ground.

Three-dimensional greening effect 2: reducing noise

Experimental results show that a 10-meter-wide forest belt can reduce noise by 30%; 250 square meters of lawn can attenuate sound by 10 decibels; a patch of plants Can reduce noise by 26-43 decibels.

1. Benefits of three-dimensional wall greening:

Build flower beds under building walls, plant climbing plants, and choose plants with climbing and adsorbent rhizomes, such as ivy, Five-leaf brocade, ivy, vine rose, etc. cover the entire wall, forming a large-area green curtain. Walls with vertical greening can reduce the wall temperature by 2 to 7°C. Especially for west-facing walls, the cooling effect is more significant after being covered with greening, achieving a relatively ideal energy-saving effect. Moreover, after the wall is covered with greenery, the air humidity can be increased by 10% to 20%, which is greatly helpful for people to eliminate fatigue and increase comfort in hot summer.

2. Benefits of greening the bridge body and pillars of overpasses:

Build flower beds or hang hanging baskets on both sides of the overpass, and plant ivy, brocade, golden and silver vines, fufang vines, etc. Drought-tolerant climbing plants can absorb dust, reduce noise, reduce temperature, and increase the green area.

Experimental results show:

A 10-meter-wide forest belt can reduce noise by 30%; a 250-square-meter lawn can attenuate sound by 10 decibels; and patches of plants can reduce noise by 26-43 decibels. ; Promotion and application (example) Example of plant ecological wall in Shanghai World Expo Theme Pavilion:

A wall can save 40% of energy and reduce air conditioning load by 15%. This is a miracle created by the plant ecological wall of the Shanghai World Expo Theme Pavilion. Not only that, such walls also have the functions of heat preservation, dust retention, noise reduction, and have a pleasant effect on people. The plant wall of the theme pavilion is 180m long and 26.3m high. The plant wall arranged on the east and west sides has a total area of ??5000m. It is currently the largest ecological green wall in the world, twice the area of ??the green wall of the Aichi World Expo in Japan. Exterior wall greening refers to a measure that people carry out vertical greening on building walls, fences, balconies, windowsills, etc., to improve the urban ecological environment. Compared with traditional flat greening, wall greening has a larger space, turning the "concrete forest" into a real green natural forest. It is a leap in people's greening concept from two-dimensional space to three-dimensional space, and is the future of greening. a new trend.

Construction of the Ecological Green Wall of the 2010 Shanghai World Expo Theme Pavilion

Seven system problems solved:

More than 80% of the Expo venues will be three-dimensional green wall

According to statistics, more than 80% of the nearly 240 venues of the World Expo have roof greening, three-dimensional greening and indoor greening. Greening experts from the Shanghai Greening Committee Office Secretariat told reporters that the three-dimensional greening layout of the World Expo venues is quite interesting. It is especially worthy of reference and study by those who pay attention to building greening.

With the widespread use of vertical greening at the Shanghai World Expo, its development in China is increasingly worth looking forward to.
