How to calculate the proportion of arbor, shrub and lawn? What is the standard of community greening?

Although every city is now in a good state of development, few cities have done a good job in greening the environment. Therefore, in recent two years, more and more people have joined the urban greening work, and to join the greening work, they must at least have a basic understanding of the greening environment. How to calculate the ratio of arbor to shrub lawn? What is the standard of community greening? Although the development of every city is very good now, few cities have done a good job in greening the environment, so more and more people have joined the urban greening work in recent two years, and joining the greening work requires at least a basic understanding of the greening environment, such as the calculation of greening rate and lawn ratio. How to calculate the proportion of arbor and shrub lawn? What is the standard of community greening?

How to calculate the proportion of arbor, shrub and lawn?

Calculation formula of greening rate: greening rate = greening area/planned construction land area The greening rate is usually controlled below the limit. The green space here includes public green space, green space beside houses and green space belonging to public service facilities (green space within the red line of roads), excluding artificial green space on roofs and balconies. Green buildings such as sculptures, pools and pavilions with an area not exceeding 1% in public green space can be regarded as green spaces. The planned construction land area refers to the land area within the red line of the project land, generally including pavement area, green area, occupied area of buildings (structures), stadiums, etc.

What is the standard of community greening?

1, greening rate is an inaccurate and nonstandard word, and the accurate formulation should be? Green coverage rate? . The green coverage rate in Hong Kong refers to the ratio of the sum of green vertical projection areas to residential land, which is relatively broad. Generally, places with grass can be counted as greening, so the green coverage rate is generally higher than that of green areas. Green rate = green area/land area.

2. The green rate is usually controlled at the lower limit: not all places with grass can be counted as green rate, and the land within 1.5m from the external wall of the building and the land within 1m from the road sideline or the land with a topsoil depth of less than 3m, regardless of whether there is greening on it, are not counted as green areas.

3. What is the green rate? What are the types of green spaces in residential areas in Hong Kong? It mainly includes public green space, residential green space, affiliated public building green space and road green space. Green buildings such as sculptures, pools and pavilions with an area not exceeding 1% in public green space can be regarded as green spaces.

At present, the country strictly manages the greening rate, because the greening rate can't reach the national standard, and no new real estate development projects are allowed. The greening rate index of residential quarters in Hong Kong is clearly stipulated by the national government not to be lower than 30%. When buying a new house, ask clearly what the greening rate of this community is. The contract should also be clearly written, otherwise the developer will not recognize it.

Learn how to calculate the proportion of trees and shrubs in the lawn. What's wrong with the greening standard of the community? The calculation of lawn proportion is actually the calculation of greening rate. The calculation method is simple, and the result is safe through formula calculation. Don't worry about insufficient greening. As for the greening work of the community, before the initial construction of the community, the property will have all-round statistics, so it is no problem to rest assured.
