城市林木滞尘效应研究进展

Research Progress on Dust Detention Effect of Urban Trees:A Review.

近年来,城市环境状况受到广泛关注。城市林木具有滞尘、缓解城市环境污染的潜力,尤其在发挥滞尘能力作用方面发挥着极其重要的作用。许多学者通过不同研究方法测定城市林木滞尘量,并筛选、排序、分级,优化配置结构,进而探究城市林木滞尘效应机制及机理,但缺乏城市林木滞尘能力的系统性研究,导致滞尘能力评价结果缺乏参考性。如何通过不同的研究方法,使城市林木滞尘效应在多尺度、多维度进行结合、延伸,并使其滞尘效应评价结果更全面可靠、更具有实际意义,是下一步研究的重点。基于前期研究,笔者对城市林木滞尘效应研究进展的相关文献进行归纳、分析和总结,并从城市林木滞尘效应测定方法、机制与机理、时空特征、环境影响要素、其他影响因素等方面总结相关进展,最终提出城市林木滞尘效应目前存在的问题,并对未来的研究进行展望。

In recent years,urban environmental pollution has become increasingly prominent and attracts widespread attention.Urban trees have the potential to trap dust and help to alleviate this type of environmental pollution.In particular,urban trees play an extremely important role in their capacity to trap dust.However,there is a lack of systematic research on the ability of urban trees to retain dust.Many researchers use different methods to screen,sort and grade tree species that have a strong ability to retain dust and optimize the allocation structure to explore these mechanisms.The differences in the methods currently used in these studies have resulted in a lack of reference for these studies.Therefore,the focus of the next step of this research is to combine and extend the effect of urban trees to retain dust using different multi-scale and multi-dimensional methods.Success with this goal should enable more comprehensive,reliable and practical methods for the evaluation of the further researches on this topic,including those on measurements,mechanisms,temporal and spatial characteristics,environmental impact factors and other influencing factors.The final goal of this paper is to address the existing problems of retention of dust by urban trees and the prospects for future research.
