摘要: 选择佳木斯市具有代表性的绿地作为对象,对不同结构绿地的空气负离子水平进行了测定。结果表明:不同结构绿地的空气负离子水平差异极显著,以乔灌草复层结构绿地空气负离子水平最高,空气质量最佳;城市不同结构绿地空气负离子浓度大小、空气质量优劣的排序均为乔灌草结构>乔草结构>灌草结构>草坪。

Abstract: Choosing representative greenbelts in Jiamusi City, Heilongjiang Province as the objectives, this paper studied the effects of different greenbelt structures on the air negative ions concentration. The results indicated that air negative ions concentration differed significantly with greenbelt structure. Multilayer structure tree-shrub-grass had the highest air negative ions concentration and the best air quality, followed by tree-grass, shrub-grass, and grass.
