Three-dimensional greening, creating a green space

AUTHOR： DATE：2018/5/7 9:44:44 VISITS：

  Urban greening and indoor greening have come into sight. More and more people pay attention to greening and improve the ecological environment. This is the primary starting point for promoting three-dimensional greening. The staff member said that after doing the vertical greening on the side of the outdoor work wall, compared with the other ungreened room, cooling in the winter and keeping warm in the summer, the energy-saving effect is significant. The original air-conditioner at the same time may consume 100 kWh, and now only needs Twenty to thirty kilowatt hours.

  Three-dimensional greening can alleviate the increasingly serious urban “heat island effect”, purify rainwater, reduce the pressure on the sewage system, and greatly improve the urban part of the environment. Under the promotion of supporting policies, enterprises and institutions are more supportive of the creation of three-dimensional landscaping, and the three-dimensional greening and transformation of office buildings have encountered less resistance. However, the residents' tolerance for three-dimensional afforestation, especially the roof greening, is still not high.

  Three-dimensional greening can be divided into roof greening and vertical greening. It is necessary to sum up elements such as building safety, load-bearing, waterproofing, selection of plant adaptability, windproof fixation of plants, and irrigation methods, which require high skills. The staff member said: "Not all houses can be green roofs. When buildings are built, they should take into account load-bearing problems, water leakage, etc." Compared with flatland greening, roof greening costs are relatively high, and they have to be maintained in the later period.

  In general, there are many large-scale public buildings in China, and the space is relatively serious. The utilization rate of roof greening is high, and many units are willing to do it. However, within the community, it is necessary to carefully consider whether the roof itself is suitable for greening, in addition to issues such as property rights. Many countries have already imposed mandatory rules on three-dimensional greening. For example, it is required that all public buildings must reach certain public greening specifications, etc. This requires the introduction of relevant guidelines to promote.

  Relevant person in charge said that more social funds should also be encouraged to participate. Some cities in China will promote the promotion of three-dimensional greening into sponge-like cities. They not only have financial rewards, but also include green space rate, volume ratio accounting, and rewards through pollution reduction and exemption. For example, after the real estate developer completes the greening and vertical greening of the roof, it can be converted into a certain green rate according to the actual situation, or some water fees can be reduced. Because the three-dimensional greening has a certain function of impounding water, it will help reduce the pressure on the city's pipe network. In this way, the enthusiasm of developers and related fund-raising units will be even greater.
