The rate of green space is used to describe the proportion of all kinds of green space in residential land, including public green space and green space beside houses.
The requirement of small public green space is that the width is not less than 8 meters, the area is not less than 400 square meters, and the green space area in the land is not less than 70% of the total area. Moreover, at least 1 3 of the green area can receive sunshine all the year round, and the land near the house within 1.5 meters from the external wall of the building and1meter from the road sideline is not included in the green land.
In real estate development, the government has set the index of green space rate, which is generally not less than 30%.
Green space rate control
The control of green space rate is related to the nature of land use and the location of lots. Different plots should have different green rate control indicators. Generally speaking, the green rate of residential land is higher than that of industrial land, the new city is higher than that of the old city, and the scenic tourist area is higher than that of the general area.
In planning, in order to encourage construction projects to provide open space, public green space and vertical green space to the public, compensation for corresponding plots should be increased.
For example, a city has specifically determined the compensation conditions, including: the net width of open space and public green space in any direction is not less than 5m, and the actual use area is not less than 50m2；; For public use all the year round, and the nature of use shall not be changed midway; There should be no major buildings on it, but it does not include arcades, traffic corridors or lighting ceilings.
The following principles should be followed in the construction project of the building area award: the principle of serving the public, the principle of opening to the public, the principle of accessibility and the principle of simultaneous implementation of construction projects.
