园林植物表面对大气颗粒物削减过程研究进展

大气颗粒物被植物表面滞留以及被雨水冲刷的过程，是植物表面将悬浮大气颗粒物转移至地面变为稳定状态的主要过程。探讨植物表面对大气颗粒物削减过程及影响机制，有利于科学评估和筛选空气净化型园林植物，提升绿地生态服务功能。文中综合现有研究，阐述植物表面滞留大气颗粒物和被雨水冲刷过程的原理，讨论植物表面对大气颗粒物的削减能力特征，探讨植物形态结构以及环境因素对植物颗粒物削减过程和能力的影响机制，最后针对现有研究中存在的不足提出了展望，以期为空气净化型园林绿地营建提供参考依据。

Research Progress in the Reduction Process of Atmospheric Particulate Matters by Landscape Plant Surface

The process that atmospheric particles are trapped on the plant surface and washed by rain is the main process that the plant surface transfers suspended atmospheric particles to the ground and keeps a stable state. To explore the process and influence mechanism of plant surface on atmospheric particulate matter reduction is conducive to the scientific evaluation and screening of air purification garden plants, and improve the ecological service function of green spaces. Based on the existing research, this paper expounds the principle of the process of atmospheric particles being retained by plant surface and washed by rain, discusses the characteristics of plant surface's ability to reduce atmospheric particles, and elaborates the influence mechanism of plant morphology and environmental factors on plant process and ability to reduce particles, and then puts forward the future research direction based on the problems in existing research. This study is aimed to provide references for the development of air purification green spaces.
