Problems solved by technology

The traditional support form does not consider the wind speed and direction of the planting area, and most of them use the method of setting support points in a balanced manner to improve the wind resistance

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 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 fil...

Embodiment 2

[0059] Such as Figure 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 of the prevailing wind direction tree hole and the center of the base tree hole θ max =0°, 90°, 315°, such as Figure 7 Shown is the obtained tree hole configuration diagram in Guangzhou.

Embodiment 3

[0061] 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, calculate the average value of the remaining wind direction ratings to obtain the basic wind direction frequency f 0 , the distance between the apex of the isosceles triangle of the prevailing wind direction tree hole and the center of the base tree hole θ max =45°, 247.5°, such as Figure 9 Shown is the obtained tree hole configuration map of Hohhot.

[0062] preferred, such as Figure 1-3 As shown, the special-shaped tree hole m...

Abstract

The present invention provides a special-shaped tree pit-based regional wind-rose diagram. The special-shaped tree pit-based regional wind-rose diagram comprises a circular basic tree pit space and aprevailing wind direction expanding tree pit space, the prevailing wind direction expanding tree pit space is located at the edge of the circular basic tree pit space, and the prevailing wind direction expanding tree pit space provides a physical environment for activating growth of part of the root system, so that the root system of trees grows toward the prevailing wind direction expanding treepit space, root-fixing ability of the trees and wind-resisting ability of the trees are thus improved.

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 ...
