PM_(2.5)小粒径大危害,城市绿化树木在一定程度上可消减PM_(2.5)污染。综述了城市绿化树木消减PM_(2.5)的作用机理,消减PM_(2.5)绿化树种的分类筛选及绿地配置模式研究,并对如何建构消减PM_(2.5)绿化树种筛选评价指标体系、城市绿地配植等进行了展望。
The PM_ (2.5) is of great harm to the small particle size. Urban greening trees can reduce PM_ (2.5) pollution to a certain extent. The mechanism of reducing urban greening PM_ (2.5), the classification and screening of PM_ (2.5) greening trees and the research on green space allocation were summarized. And how to build a screening evaluation index system for eliminating PM_ (2.5) green tree species, And so on.
