摘要：【目的】本文以杭州国家半山森林公园和采荷社区为研究地点,揭示城市森林对TSP、PM_(10)、PM_(2.5)和PM_14种不同类型大气颗粒物浓度变化的影响。【方法】对TSP、PM_(10)、PM_(2.5)和PM_14种不同类型大气颗粒物的浓度进行了周期为1年的定点监测,通过对比分析城市森林区和城区的不同类型大气颗粒物浓度的变化差异。【结果】半山监测点的TSP、PM_(10)、PM_(2.5)以及PM_14种大气颗粒物浓度的日变化曲线为早上9:00到达最大值,然后随时间变化而持续减少,在下午14:00到达最小值,分别为:182.2、124.2、68.2、20.6μg·m^(-3);在采荷社区,4种大气颗粒物浓度由早上9:00开始降低但到下午17:00时又基本上升到早上9:00的水平;在半山监测点相比采荷,PM_(2.5)和PM_1浓度年变化的峰值均延迟了1个月的时间,城市森林区和城区的不同类型大气颗粒物浓度的日变化和月变化规律存在明显的不同。【结论】4种不同类型大气颗粒物的平均浓度均为半山森林公园高于采荷社区;在半山和采荷2个监测点的PM_(2.5)和PM_1浓度的差异分别显示为有高度统计意义和有统计意义。
【Objective】The concentration of different types of atmospheric particulate matter(TSP,PM10,PM2.5 and PM1)were monitored in the Hangzhou Banshan national forest park and Caihe community for one year.【Method】Through the contrast analysis of different types of atmospheric particulate matter concentration in typical urban forest area and urban area,the effect of urban forest on atmospheric particulate matter concentration was revealed.【Result】The results showed that the concentration of TSP,PM10,PM2.5 and PM1 in Bashan monitoring site both reached the maximum at 9:00 am and then decreased continuously with time and reached the minimum at 14:00 pm,182.2,124.2,68.2,20.6μg·m^-3,respectively,but the four atmospheric particulate matter decreased from 9:00 to 17:00 when they basically rose to the level of 9:00 am at Caihe community.【Conclusion】The peak values of annual changes in concentrations of PM2.5 and PM1 were delayed by one month at Banshan site compared to those at Caihe sites.The diurnal and annual variation patterns of atmospheric particulate matter concentrations in typical urban forest areas and urban areas were significantly different in Hangzhou.The mean concentrations of four different types of airborne particles were both higher than those of the community.The concentrations of PM2.5 and PM1 at the Banshan and Caihe have highly statistically significant and statistically significant,respectively.
