Problems solved by technology

[0005] 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 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

[0040] Such as figure 1 As shown, a strip-shaped three-dimensional hybrid noise-reduction urban forest configuration method is as follows:

[0041] (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.

[0042] (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 1.2-1.5 m.

[0043] (3) Rows of tall shrubs 6 , second trees 7 ...

Embodiment 2

[0054] Take the urban forest configuration method on Xiangzhang Avenue in Shufengwan Sports Park, Hefei City, Anhui Province as an example.

[0055] 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.

[0056] The forest belt is mainly composed of four rows from the roadway to the noise-sensitive target direction:

[0057] 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 2 m. Plant 1-2 rows on the side; form the upper, middle and lower layers of vertical canopy forest belts, and gradually attenuate the roadway through their "blocking-absorbing-reflecting-blocking-reabsorbing-rereflecting" noise.

[0058] The second row is located on the outside of the sidewalk away from the roadway: it is densely planted with osmanthus flowers abou...

Embodiment 3

[0064] 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.

[0065] 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.

[0066] The forest belt is mainly composed of four rows from the roadway to the noise-sensitive target direction:

[0067] 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 2 m; 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.

[0068] The second row is located on the...

Abstract

The invention provides an allocation method of a belt-shaped three-dimensional mixed noise reducing type urban forest. The method comprises the following steps: (1) selecting plants; (2) planting a row of first arbors in the outer side of a roadway along the roadway direction, and densely planting dwarf shrubs around the first arbors to form a first allocation area; (3) sequentially outwards planting rows of tall shrubs, second arbors and second herbaceous plants in the outer side of the first allocation area to form a second allocation area, wherein the second allocation area and the first allocation area are separated through a sidewalk; (4) enabling the width sum of the second allocation area and the first allocation area to be 30 to 35m, and length to be not less than that of a noise sensitive target along the roadway direction. According to the allocation method of the belt-shaped three-dimensional mixed noise reducing type urban forest, proper arbors, shrubs and herbaceous plants are selected and allocated to form a mixed forest zone with a certain width in the side of the roadway, and therefore, the noise can be repeatedly absorbed and reduced at a plurality of times during being transmitted in the space, and as a result, the purpose of noise reducing can be reached, the noise can be reduced by 28.3%.

Description

Technical field [0001] The present invention involves a urban greening method, which specifically involves a three -dimensional mixed noise reduction city forest configuration method. [0002] Background technique [0003] Nowadays, the impact of environmental noise on the health of urban residents has become increasingly the focus of people's attention. Due to the increasing number of vehicle transportation, the environmental noise intensity caused by its 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 environmental noise energy, especially the noise pollution near traffic roads is more serious. [0004] According to research, plants can improve the ecological environment of the city, such as regulating air quality, absorbing carbon dioxide released in the city, and alleviating the effects of heat islands, thereby regulating the climate of the city, r...
