A boulevard suitable for urban parallel street canyons

Abstract

The invention discloses an avenue applicable to a city parallel street canyon. A cross section structure of the avenue is sequentially a one-way avenue, a non-motor vehicle way, a non-motor vehicle isolation green belt, a motor vehicle way, a motor vehicle isolation green belt, a motor vehicle way, a non-motor vehicle isolation green belt, a non-motor vehicle way and a one-way avenue; the motor-vehicle isolation green belt is a high-low alternate micro canyon motor-vehicle isolation green belt formed by a 'high and large plaque combined type' isolation green belt and a 'short dredging open type' isolation green belt which are arranged at intervals; the non-motor isolation green belt is an 'open forest-flower mirror type' non-motor isolation green belt. The avenue applicable to the city parallel street canyon can effectively reduce concentration of air pollutants (NOx and SO2) in breathing areas for pedestrian of sidewalks and the non-motor vehicle ways in a parallel street canyon avenue, and the aims of purifying ambient air of the city and improving environmental quality of a city avenue are achieved; a method is simple, cost is low, and the avenue applicable to the city parallel street canyon is easy to build and applicable to popularization in cities.

Description

technical field [0001] The invention relates to the technical field of gardens, in particular to a boulevard suitable for urban parallel street canyons. Background technique [0002] With the development of the economy and the increase of population density, the number of large and medium-sized motor vehicles has increased rapidly, and the pollution caused by traffic in urban street canyons has also continued to rise, directly affecting the quality of life of urban residents. The traffic gaseous pollutants in urban streets and canyons mainly come from the exhaust emissions of various motor vehicles, among which sulfur dioxide (SO 2 ) and nitrogen oxides (NO x ) is harmful to the road environment, especially the air on both sides of urban streets, within a horizontal distance of 50m and a height of 1.7m. This range is also in the breathing zone of pedestrians, directly affecting the health of pedestrians and surrounding residents. Therefore, how to choose the appropriate ro...

Problems solved by technology

[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to propose a solution from the aspects of road slab type, street tree and machine non-isolated green belt structure, plant selection and configuration in the isolated green belt in the urban parallel street canyon. Suitable for air pollutants in urban parallel street canyons (NO x and SO 2 ) concentration reduction boulevards, to achieve the purpose of purifying the ambient air of urban streets and improving the ambient air quality of urban boulevards
