绿色植物具有防止和减轻污染环境的能力,对美化和保护环境有着积极作用。在工业“三废”比较集中的城市,工矿区绿化工作更为重要。 二氧化硫是当前最主要的大气污染物。发生二氧化硫的污染源比较普遍,而且排放量大。氟化物、氯气散放虽比二氧化硫少,但对人和家畜危害严重。为了减轻城市和工矿区的污染,最好选择具有较强抗污和净化空气能力的植物因地制宜地栽培。现介绍20几种果树和花卉供栽植参考。
Green plants have the ability to prevent and reduce pollution of the environment, to beautify and protect the environment has a positive effect. In the cities where industrial “three wastes” are relatively concentrated, greening in industrial and mining areas is even more important. Sulfur dioxide is currently the most important air pollutant. Sulfur dioxide pollution sources are more common, but also large emissions. Fluoride, chlorine release less than sulfur dioxide, but serious harm to humans and livestock. In order to reduce pollution in cities and industrial and mining areas, it is best to choose plants with strong anti-fouling and air purification ability to be cultivated according to local conditions. Now introduce 20 kinds of fruit trees and flowers for planting reference.
