199 1 year, the Tokyo Metropolitan Government promulgated the Urban Greening Law, which stipulated that greening schemes must be put forward when designing buildings. 1992 formulated the Guidelines for Greening Schemes of Urban Buildings, which made urban greening more concrete. The Tokyo Urban Greening Campaign was initiated by a high-grade roof development research institute composed of 48 companies including Tokyo architecture and landscape architecture, and received strong support from the Tokyo Metropolitan Government. There are many small roof gardens and hanging gardens in Tokyo, Japan, which not only attract many tourists, but also benefit the citizens of Tokyo. In order to make Tokyo a green city in 2 1 century, Japan has adopted many new technologies in green roof construction, such as artificial soil, automatic irrigation devices, and even planting techniques to control plant height and root depth.
1999 Dongguan Geng Xin Eco-environmental Engineering Co., Ltd. launched the three-dimensional flower wall for the first time, which caused a sensation in China. Later, many three-dimensional greening models spread at a limited speed. The greening of three-dimensional flower wall in Geng Xin is the foundation of green building, which significantly improves the quality of high-altitude civilization. Three-dimensional wall greening can not only purify the air, but also greatly increase the content of negative oxygen ions. Its characteristics are radiation protection, in addition to formaldehyde and ventilation to improve artistic accomplishment and cultivate life sentiment.
In 2007, Shenzhen Heruntianze Environmental Technology Development Co., Ltd. was established. Is a three-dimensional greening company specializing in design, installation and maintenance. Starting from the high starting point of introducing foreign advanced technology, we have carried out localized innovation, successfully developed a world-class three-dimensional greening technology suitable for China's national conditions and with independent property rights, and applied for a national patent. Three-dimensional greening must be grasped with both hands, and both hands must be hard. There should be both encouraging and mandatory policies. Encouragement policies include government subsidies and free technical support; Compulsory policies are mainly aimed at public infrastructure and commercial development. Through the rigid requirements of architectural design and planning, developers are urged to require green space in the air.
20 10 The greening of the plant walls and roofs of the Shanghai World Expo attracts attention. Since then, a large number of excellent three-dimensional greening enterprises have emerged in Taiwan Province Province and Chinese mainland, China. Representative technologies include chain-touching basin group technology, modular planting technology, plant bag planting technology and so on. These technologies have been successfully and widely used in Shanghai, Wuhan, Guangzhou, Hangzhou and other cities, and have been unanimously recognized by the general public. Many foreign countries stipulate that brick walls and cement walls are not allowed to be built in cities, but "ecological walls" must be built. The specific method is to plant trees at equal distances along the wall, with climbing vines in the middle, and can also be supplemented by wrought iron nets. This is a labor-saving, material-saving and practical form, which not only achieves the effect of vertical greening, but also plays the role of infiltration greening. Singapore, a "garden city", is full of lush vegetation, and the three-dimensional greening submerges the building in a piece of green. The open spaces in many cities in the United States are almost covered with green grass, and Lvmu flowers and plants are planted on the guardrails and building walls of major supermarkets in an attempt to increase the amount of green; Chicago also has a rooftop garden, which is also very popular. The Ministry of Environment of Chicago decided to design and build various roof gardens, which can save the city government's summer expenses, save 40 million dollars in cooling expenses for building new roofs every year, and its duration will be half as long as that of traditional roofs. Multi-layer special soil is designed, and polystyrene material, eggshell cone and waterproof membrane are used to prevent the roof from leaking because it can't bear the total weight of soil, sprinkler and plants. The roof garden will be planted with various plants, such as wild onion, red peach grass, aster azure and wild cowherb. Budapest, Hungary is also a garden city with blooming flowers. Every balcony of the residential building in this city is covered with vines, and pots of flowers are also placed on every staircase and corner platform. .
With the emergence of plants and flowers in hanging gardens, planting green plants on balconies or roofs is also very common in Europe. Roof gardens of some urban institutions, schools, commercial buildings and residential buildings can be seen everywhere in Europe. Three-dimensional greening can not only give people a good psychological effect, but also improve the environment, purify the air and beautify the city. At the same time, it also plays a role in heat insulation, energy saving and noise reduction for the building itself. Therefore, it is of great benefit to do a good job in three-dimensional greening.
