-I'm a gorgeous dividing line.
Urban greening needs space. In cities with scarce land, space has become the object of fierce competition between architecture and greening. In the contradiction between the two, the good wish of "greening" needs to be realized in many ways to a great extent. Vertical greening is the best way.
Vertical greening, also known as three-dimensional greening, is to make full use of space and plant climbing plants on walls, balconies, windowsills, roofs, scaffolding and other places to increase the green coverage and improve the living environment. It can not only increase the artistic effect of buildings and make the environment cleaner, more beautiful and more vivid, but also has the advantages of less land occupation, quick effect, high greening rate and more environmental protection. Its basic forms are: vertical wall greening, roof greening, interchange greening, fence greening, slope protection greening, courtyard greening, residential greening and indoor greening.
In recent ten years, with the acceleration of urbanization in China, the population and scale of cities have been further expanded, the available land in cities has been more and more restricted, and the pressure of urban greening has been increasing. Landscaping units in large and small cities all over the country are studying and discussing how to realize vertical greening of cities locally. At present, many cities have gained successful experience, and vertical greening is increasingly favored by all localities and gradually becomes the mainstream of urban greening.
Firstly, vertical greening is a mature technology. Secondly, the climate of Lu Yi is suitable for vertical greening. Wang Jintao, director of the Department of Landscape Architecture of Forestry College of Henan University of Science and Technology, believes that Henan is a typical warm temperate continental monsoon climate, with cold and dry winter, hot and rainy summer and no extreme weather, which is very suitable for developing vertical greening. But the main reason is-
As an important form of urban greening, vertical greening of urban space has two major advantages:
? ? 1. is conducive to the restoration of urban construction. Effectively overcome the constraints of insufficient urban greening area, effectively beautify urban buildings and enhance urban cultural atmosphere.
? 2. Conducive to the restoration of urban ecology. First, it can effectively reduce building energy consumption, which is conducive to energy conservation and emission reduction. For buildings with good vertical greening (roof greening), the temperature of ventilated rooms can be reduced by 2℃ to 3℃ in summer, and the temperature of closed rooms can be reduced by 5℃ to 8℃. Roof greening will play a positive role in energy saving of the whole building, which can save energy by about 30%. Second, it can improve air quality and climate conditions. Vertical greening (roof greening) conforms to the green space design concept advocated by the state at present and is the best way to improve the urban ecological environment. Vertical greening (roof greening) can absorb pollutants in the air and reduce dust in the air. Roof greening can absorb about 20g of dust per square meter. According to this calculation, a roof green space of 100 square meter can retain about 2kg of dust, which can reduce the dust content in the atmosphere and is very effective in reducing PM2.5
Vertical greening not only occupies less land, has quick effect and high greening rate, but also can increase the artistic effect of buildings and make the environment cleaner, more beautiful and more vivid. In urban greening construction, various vertical greening sketches, such as rattan corridors, arches, fences, scaffolding and hanging baskets, are carefully designed. , can make the whole city more three-dimensional, not only enhance the greening and beautification effect, but also increase people's activities and leisure space. Therefore, vertical greening can greatly improve the quality of urban construction in Lu Yi and lay a solid foundation for striving for a national garden city.
1. Xiamen? This city is one of the earliest cities in China to implement vertical greening. Since 2005, as a new attempt to build an ecological civilization, vertical greening has begun. Ten years later, vertical greening has been deeply rooted in people's hearts. In 2005, Xiamen landscaping management department began to promote balcony greening activities. In 2006, Xiamen Municipal Party Committee and Municipal Government expanded balcony greening activities and implemented vertical greening construction in Xiamen Island. In order to expand its influence, the Municipal Greening Office organized a grand launching ceremony. In 2008, Siming District and Huli District of the city held the mobilization meeting of vertical greening work in the whole region respectively. The sub-district offices under the jurisdiction of the two districts have worked out the work plan of street vertical greening according to their own conditions, and selected the demonstration sites of vertical greening construction. At the same time, the joint news media carried out vertical greening propaganda, held on-site work experience exchange meeting, and effectively promoted the vertical greening work in Xiamen through a series of activities such as sending balcony flowers, distributing vertical greening knowledge brochures, and giving professional and technical guidance on greening.
2. Beijing. In order to speed up the process of vertical greening in Beijing, Beijing issued the Opinions on Promoting the Construction of Vertical Greening in Urban Space (20 12). The Opinions pointed out the general idea and main principles of promoting the vertical greening of urban space, defined the main tasks and sources of funds for roof greening and vertical greening, defined the relevant policies and measures and supervision subjects for greening, and refined the organizational guarantee and division of responsibilities. The promulgation of "Opinions" is of milestone significance for Beijing to promote the vertical greening of urban space and points out the direction for the city to promote the vertical greening construction.
3. Luoyang 20 14 formulated the city's roof greening standards according to the technical specifications of roof greening in Henan province, and promoted 14 unit (community) as a demonstration site for roof greening.
There are two main ways of greening in Lu Yi urban area: vertical greening of outdoor walls-solving the problem of aging and unsightly walls along the street; Roof Greening-Solve the problem of disorderly building colored steel houses (sheds) on the roofs of buildings. At the same time, encourage courtyard and residential greening (balcony, colonnade, scaffolding greening).
1. Wall greening. Firstly, the buildings along the main streets of the city and the walls of low-rise residential buildings with serious aging are vertically afforested, and then gradually popularized in secondary streets. When greening, absorbent plants with strong vitality should be selected, such as ivy, wisteria, ivy, lingxiao, trachelospermum, bougainvillea, wisteria, clematis, golden vine, blue snowflake and morning glory, so that they can grow rapidly on various vertical walls. In addition, when greening the fence, climbing plants should be planted in the form of scaffolding and covered with rigid wall doors to achieve the effect of flowers in summer and fruits and leaves in autumn.
2. Roof greening. First, the owners of public buildings, government agencies and units, and the roofs of buildings will randomly build colored steel houses (sheds) for greening, and then gradually and comprehensively green the roofs, rooftops and terraces of various buildings and structures in the city. In order to avoid the high cost of roof greening, we should try not to use soilless culture technology, but choose lianas that are easy to live and raise.
? (2) Precautions
? 1. Step by step. Vertical greening is a new thing for Lu Yi, which needs to be implemented step by step according to the principle of gradual progress to avoid making a mountain out of a molehill.
? 2. In-depth launch and extensive publicity. We should be patient with the masses and do a good job in ideological work.
