Problems solved by technology

[0004] At present, the preferred method to control road noise is to use sound-proof tiles. Although its construction cost and maintenance cost are very high, it can only protect the sound-proof tiles to directly block part of the noise, and most other spaces still cannot be protected; the second is to use shelter forests. , but most of the shelterbelts currently used are single tree species, and the protection mode is similar to that of soundproof tiles, which can only reduce the noise in the directly shielded area

Embodiment 1

[0036] Such as figure 1 As shown, a strip-shaped three-dimensional hybrid noise-reduction urban forest configuration method is as follows:

[0037] (1) Select the first evergreen tree 5, the second tree 7, the dwarf shrub 11, the tall shrub 6, the first herb 12, and the second herb 8 that are luxuriant and fast-growing; the first arbor 5 1. The height of the second tree 7 is not less than 7m, the height of the dwarf shrub 11 and the tall shrub 6 is not less than 2m, and the height of the first herb 12 and the second herb 8 is not less than 20cm.

[0038] (2) Plant a row of first arbors 5 along the direction of the roadway on the outer side of the roadway 9, and densely plant dwarf shrubs 11 around the first arbor 5, and then densely plant them on both sides along the roadway and sidewalk There are first herbaceous plants 11, forming a first configuration area 1, and the width of the first configuration area 1 is 1.2-1.5m.

[0039] (3) Rows of tall shrubs 6 , second trees 7 a...

Embodiment 2

[0050] Take the urban forest configuration method on Xiangzhang Avenue in Shufengwan Sports Park, Hefei City, Anhui Province as an example.

[0051] Among them, the main trees are camphor, privet and acacia, the main shrubs are sweet-scented osmanthus and heather, and the main herbaceous plants are green onion, Ophiopogon japonicus and albizia.

[0052] The forest belt is mainly composed of four rows from the roadway to the noise-sensitive target direction:

[0053] The first row is located between the roadway and the sidewalk: it is composed of camphor + phoenix + onion orchid, and the plant spacing of camphor is 2m. Plant 1-2 rows at the side; form the upper, middle and lower layers of vertical closed forest belts, and gradually attenuate the roadway through their "blocking-absorbing-reflecting-blocking-reabsorbing-rereflecting" noise.

[0054] The second row is located on the outside of the sidewalk away from the roadway: it is densely planted with osmanthus flowers about...

Embodiment 3

[0059] Take the urban forest allocation method on the south side of Changjiang West Road, east of the intersection of Changjiang West Road and Yulan Avenue in Hefei City, as an example to illustrate.

[0060] Among them, the main trees are plane tree, Huangshan eucalyptus, Albizia juniperus and poplar, the main shrubs are tall phoenix phoenix, and the main herbaceous plants are Ophiopogon japonicus, step grass and clover.

[0061] The forest belt is mainly composed of four rows from the roadway to the noise-sensitive target direction:

[0062] The first row is located between the roadway and the sidewalk: it is composed of syringa + privet + Ophiopogon japonicus, the distance between the plants of sycamore is 2m; Plant 1-2 rows; form the upper, middle and lower layers of vertical canopy forest belts, and gradually attenuate the noise generated by the roadway through their "blocking-absorbing-reflecting-blocking-reabsorbing-rereflecting" .

[0063] The second row is located o...

Abstract

The invention provides a strip-shaped three-dimensional hybrid noise-reducing urban forest configuration method, including (1) selecting plants; (2) planting a row of first trees along the direction of the road on the outside of the roadway, and planting a row of first trees around the first tree Densely planting dwarf shrubs to form a first configuration area; (3) planting rows of tall shrubs, second trees and second herbaceous plants on the outside of the first configuration area in order to form a second configuration area; the second configuration area Separated from the first configuration area by a sidewalk; (4) The sum of the width of the second configuration area and the first configuration area is 30-35m, and the length is not less than the length of the noise-sensitive target along the roadway. The present invention selects suitable trees, shrubs and herbaceous plants for configuration, and builds a mixed forest belt of a certain width on the side of the roadway, so that the noise can be repeatedly and repeatedly absorbed and weakened in the process of space transmission, thereby achieving the purpose of noise reduction. Its noise reduction rate can reach 28.3%.

Description

technical field [0001] The invention relates to an urban greening method, in particular to a strip-shaped three-dimensional hybrid noise-reducing urban forest configuration method. Background technique [0002] Nowadays, the impact of environmental noise on the health of urban residents has increasingly become the focus of attention. Due to the increasing number of vehicles and vehicles, the intensity of environmental noise caused by their operation is getting higher and higher. At present, traffic noise is the main source of urban environmental noise pollution. Its energy usually accounts for 70% to 80% of the total energy of environmental noise, especially the noise pollution near traffic roads is more serious. [0003] According to research, plants can improve the ecological environment of the city, such as adjusting air quality, absorbing carbon dioxide released in the city, and alleviating the heat island effect, thereby regulating the urban climate, reducing the use of...
