Embodiment 1

[0039] The special-shaped tree hole based on the regional wind rose diagram, including the circular basic tree hole space and the prevailing wind direction extended tree hole space, the prevailing wind direction expanded tree hole space is set at the edge of the circular basic tree hole space, and the circular basic tree hole space is the bottom surface Radius is R 0 The cylindrical, prevailing wind direction extended tree hole space is a tree hole with extended edges determined according to the wind direction rose diagram, figure 1 The wind direction rose diagram determined according to the prevailing wind frequency direction and wind direction frequency in Shanghai, figure 2 based on figure 1 Determined heterogeneous tree-cavity structure.

[0040] In the preferred scheme, the depth of the circular base tree hole space is the same as that of the tree hole space expanded in the prevailing wind direction, and the tree hole space expanded in the prevailing wind direction is ...

Embodiment 2

[0060] like Image 6 As shown, it is the wind direction rose diagram of Guangzhou, where 0°, 90° and 315° are the larger wind direction frequencies. Since the three larger wind frequency directions are not adjacent, the prevailing wind frequency direction θ max to three, and then remove the prevailing wind direction frequency f max and the larger prevailing wind direction frequency, the remaining wind direction frequencies are averaged to obtain the basic wind direction frequency f 0 , the distance between the apex of the isosceles triangle that expands the tree hole in the prevailing wind direction and the center of the circular base tree hole θ max =0°, 90°, 315°, such as Figure 7 Shown is the obtained tree hole configuration diagram in Guangzhou.

Embodiment 3

[0062] Figure 8 As shown, it is the wind direction rose diagram of Hohhot, which has higher wind direction frequency at 22.5°, 45°, 225°, and 247.5°. Since 22.5° is adjacent to 45°, the frequency of wind direction is higher in these two directions 45° as the prevailing wind frequency direction θ max ;, 225° and 247.5° are also adjacent, in these two directions, 247.5° with a higher wind direction frequency is selected as the prevailing wind frequency direction θ max , after removing the wind direction frequencies in the above four directions, average the remaining wind direction frequencies to obtain the basic wind direction frequency f 0 , the distance between the apex of the isosceles triangle that expands the tree hole in the prevailing wind direction and the center of the circular base tree hole θ max ==45°, 247.5°, such as Figure 9 Shown is the obtained tree hole configuration map of Hohhot.

[0063] preferred, such as Figure 1-3 As shown, the special-shaped t...

Abstract

The invention provides a special-shaped tree hole based on the regional wind rose diagram, including a circular base tree hole space and a prevailing wind direction expanded tree hole space, the prevailing wind direction expanded tree hole space is set at the edge of the circular basic tree hole space, and the prevailing wind direction expands the tree hole space The space provides a physical environment for activating the growth of this part of the root system, so that the root system of the tree expands the space of the tree hole to grow in the prevailing wind direction, thereby improving the root-fixing ability of the tree and increasing the wind resistance of the tree.

Description

technical field [0001] The invention relates to the field of special-shaped tree holes, in particular to a special-shaped tree hole based on a regional wind rose diagram. Background technique [0002] In recent years, many areas have been affected by climatic disasters such as strong winds and heavy rainfall, which have caused varying degrees of breakage and lodging of urban greening trees, which have brought serious economic losses and even casualties to landscaping projects, and have also brought heavy burdens to local governments. post-disaster restoration work. At the same time, the promotion of green roofs has a higher demand for the windproof and root-fixing capabilities of large trees. Therefore, alleviating the occurrence of windfall of large trees and ensuring the wind resistance of trees have become the focus of current landscaping projects. The traditional windproof method is to artificially set above-ground supports or underground hidden supports to ensure the ...
