城市绿化植物滞尘效益研究综述

Study on dust retention benefit of urban greening plants

城市绿化植物在空气净化中具有阻滞粉尘的效应,但不同植被类型、时空条件下,其滞尘效益存在明显差异,为探寻其规律性,实现城市绿化植被的合理规划,将融合城市空气中PM类颗粒粉尘的优化降解为目标导向,结合以往研究成果,综述城市绿化植物滞尘效益产生机理、滞尘量、时空演变规律性,并探讨了植物滞尘效益的主要影响因子,以为城市生态环境建设提供有效参考.

Urban greening plants had the effect of blocking dust in air purifcation, but there were obvious differences in dust removal effciency in different vegetation types and space-time conditions, in order to explore its regularity, realize the rational planning of urban greening vegetation. It integrated the optimization degradation of PM particle dust in urban air as the goal oriented, combined with previous research results ,to review the mechanism, dust retention and spatiotemporal evolution of dust retention in urban greening plants, and the main factors affecting the effciency of plant dust retention were discussed, so as to provide an effective reference for the construction of urban ecological environment.
