中文摘要	【目的】城市森林可通过多种方式降低大气颗粒物的浓度,对城市环境空气质量提升具有重要意义。【方法】本文基于乌鲁木齐市南郊燕尔窝生态林地内外不同监测点位大气颗粒物的实时监测数据,对城市森林削减颗粒物能力进行了分析。【结果】 ① 3种大气微颗粒物(PM_(10)、PM_(2.5)、PM_(1.0))季节变化趋势较为一致,均表现为冬季>秋季>春季>夏季,且夏秋两季城市森林外部大气微颗粒物浓度高于生态林内部,冬、春两季会在林地中央形成一块颗粒物浓度较高的"穹顶区域";②夏、秋两季城市森林对大气颗粒物的削减作用为正,而冬、春两季对大气颗粒物的削减作用为负,说明夏、秋两季对颗粒物的削减作用大于冬春两季;③降雨天气会影响大气中微颗粒物的积累,降雨当天颗粒物浓度在较低水平且能持续一定时间,雨后3 d虽逐步升高,但仍低于雨前一天浓度。【结论】不同季节生态林对不同粒径颗粒物浓度的削减效率不同,降雨能中断生态林内对大气颗粒物的富集过程,可以有效降低空气中大气颗粒物的浓度。
英文摘要	【Objective】Urban forest can reduce the concentration of particulate matter in various ways,which is of great significance to urban environmental air quality.【Method】The cutting ability of ecological forest for different diameter particles were analyzed based on the realtime monitoring data of atmospheric particulates in Yanerwo ecological forest in Urumqi.【Result】(i)The seasonal change of three kinds of particulate matter(PM_(10) and PM_(2.5) and PM_(1.0))was relatively consistent,both the performance for the winter >autumn >spring >summer, and particle concentration ecological forest internal higher than external.(ii)The reduction rate of ecological forest to particulate matter in spring,summer and autumn was negative,while in winter was positive,indicating that the interception effect of spring,summer and autumn on particulate matter was greater than that in winter.(iii)The concentration of the particulate matter on the day of the rain was kept at a low level,and the rain was gradually raised in three days after the rain,but it was still lower than the day before the rain,indicating that the rainfall could effectively reduce the concentration of the atmospheric particulate matter in the air.【Conclusion】In different seasons,ecological forests have different reduction efficiencies for the concentration of particle sizes.Rainfall can interrupt the enrichment process of atmospheric particles in ecological forests and can effectively reduce the concentration of atmospheric particles in the air.
