7种常绿阔叶植物滞尘效应与小环境空气质量关系的研究

Study on the relationship between dust retention effect and small ambient air quality of seven evergreen broad-leaved plants

为研究常绿阔叶植物的滞尘能力与其所在小环境空气质量的关系,以石家庄市区内种植的常绿阔叶植物和其所处的小环境为对象,对石家庄市内不同季节植物叶片的滞尘量和小环境空气质量进行统计分析。结果表明:大部分情况下常绿阔叶植物的滞尘能力和空气质量指数呈极显著正相关,中华石楠综合滞尘能力较强,冬青卫矛综合滞尘能力良好,广玉兰综合滞尘能力一般,刚竹、红叶石楠、大叶女贞、早园竹综合滞尘能力较弱。植物的滞尘量与季节变化规律有对应关系,呈现秋季>冬季>春季>夏季的规律。此研究结果可以为石家庄市区内常绿阔叶植物的选择提供依据。

In order to study the relationship between the dust trapping capacity of evergreen broad-leaved plants and the air quality of their small environment,the dust trapping capacity of evergreen broad-leaved plants and their small environment in Shijiazhuang city in different seasons were statistically analyzed.The results showed that in most cases,the dust trapping capacity of evergreen broad-leaved plants was positively correlated with the air quality index,The comprehensive dust retention ability of Photinia beauverdiana is strong,while the comprehensive dust retention ability of Euonymus japonicus is good,while the comprehensive dust retention ability of Magnolia grandiflora is average.The comprehensive dust retention ability of Phyllostachys sulphurea,Photinia×fraseri,Ligustrum lucidum,and Phyllostachys propinqua is weak.There is a corresponding relationship between the amount of dust retention in plants and the seasonal variation pattern,showing a pattern of autumn>winter >spring >summer.This study can provide basis for the selection of evergreen broad-leaved plants in Shijiazhuang urban area.
