园林绿化树种枝叶滞尘效果分类研究

Study on Classification of Dust-blocking Effect of Branches of Landscaping Tree Species

园林绿化树种的滞尘能力是评价其园林绿化效果的重要指标。通过对黑龙江省主要园林绿化树种在不同环境条件下的枝叶滞尘效果测定,先将49种(类)园林绿化树种的滞尘能力划分成5个等级,然后用判别分析法进行订正,得出科学合理的分级结果。

Dust-blocking ability of landscaping tree species is the main index to evaluate the effect of landscaping.In this paper, the effects of dust-blocking under different environment were determined in Heilongjiang Province .The dust-blocking ability of 49 landscaping tree species was divided into 5 grades.
