摘　　要：总结城市绿化植物滞尘效益的研究现状,系统阐述不同主体下植物滞尘量的高低以及时空角度下城市绿化植物的滞尘规律。不同植物种在滞尘量方面存在很大差异,从群落角度来看,多层次的植物群落结构能够发挥最大滞尘效益。从时空变化上来看植物的滞尘过程是一个复杂的动态平衡过程。植物滞尘量的大小主要受到植物叶片特性、树冠枝叶结构密度、叶面倾角以及气象等因素的影响。同时,植物粉尘抗性、地被植物和垂直绿化植物滞尘效益、植物滞尘机理研究以及城市绿地滞尘总量估算可能成为今后研究的主要内容。The purification effect of urban green land for urban air is one of the important ecological functions. This paper sum- marizes the dust detaining capability of different trees and regular patterns in different temporal and spatial variation. The dust catching capacity of different tree species was prominently different. From the perspective of community, multi-level plant communities can im- prove urban air significantly. From the perspective of temporal and spatial variation, the process of dust retention is a complicated dy- namic process. Leaf characteristics, canopy structure, vane incline angle and meteorological conditions are the main factors of affect- ing dust detaining capability. Meanwhile, the dust resistance of plants, ground vegetation, vertical green plants dust detaining effect, plant dust detaining mechanism as well as dust detaining quantity of urban green land will become the future research contents.
