Embodiment

[0080] refer to figure 1 The road shelterbelt configuration method of the regulation and control atmospheric particulate matter of the present embodiment comprises the following steps:

[0081] Step S01, evaluating the functional differences of different tree species in blocking particulate matter, and evaluating the stress resistance of different tree species;

[0082] The method for evaluating the functional differences of different tree species in blocking particulate matter is as follows: select at least 5 sample trees for each species, and collect enough leaves in four different directions and different positions of high, middle and low in the canopy; Take 30-40 pieces, take 150-300 pieces for the smaller ones; take 30-50 clusters of needle leaves; put the selected plant leaf samples into a beaker filled with pure water or deionized water, and use a small brush that does not shed hair Carefully clean the attachments on the leaves, then carefully clip the leaves with twee...

Abstract

The invention discloses a road protection forest configuration structure and a method for regulating and controlling atmospheric particulates. The method comprises the following steps: according to function differences of different tree varieties in barring particles, classifying the tree varieties into ones with high particle barring performance, medium particle barring performance and low particle barring performance; according to function differences of different tree variety configuration modes in barring the particles, classifying configuration modes of different tree varieties into ones with high particle barring performance, medium particle barring performance and low particle barring performance; according to different protection function requirements of roads, selecting appropriate trees and bushes with good stress resistance; further determining ratios of broad-leaved trees to needle-leaved trees; further selecting appropriate frost structures; finally configuring frosts of road protection frosts for reducing damage of particles. Varieties of trees and bushes, the ratios of broad-leaved trees to needle-leaved trees, canopy densities, porosity degrees, leaf area indexes, ground cover areas and the like are taken into account in configuration, functions of the frosts in barring particles are taken into play, and the damage of the particles to health of human beings is reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of atmospheric particulate matter control, in particular to a road protection forest configuration structure and method for regulating atmospheric particulate matter. 【Background technique】 [0002] Particulate matter (PM) is a general term for liquid and solid particles in the atmospheric environment, and is the primary pollutant in most cities in my country. According to particle size, it can be divided into dust fall (aerodynamic equivalent diameter greater than 10 μm, PM >10 ) and floating dust (the aerodynamic equivalent diameter is less than or equal to 10 μm). Particles with an aerodynamic equivalent diameter less than or equal to 10 μm are respirable particulate matter (PM 10 ), which can be divided into coarse particulate matter (the aerodynamic equivalent diameter is between 2.5 and 10 μm, PM 2.5-10 ) and fine particulate matter (aerodynamic equivalent diameter less than or equal to 2.5 μm,...
