摘　　要：在北京大兴南海子公园内选取森林植被区,并分别对远离林带1、5、15、30、50m处的PM_(2.5)浓度进行全天连续监测,分析远离林带不同距离对PM_(2.5)浓度的影响及其日变化特征。结果表明:林内及距林带不同距离处PM_(2.5)日变化趋势相同,从早到晚均呈先降低后增加的趋势,PM_(2.5)浓度最小值出现在15:30左右,最大值出现在05:00—07:00;远离林带的距离对PM_(2.5)浓度有显著影响,随远离林带距离的增加,其浓度先降低而后增加,在距林带30m处PM_(2.5)浓度达到最低值,说明森林对颗粒物的削减作用最强。Selecting vegetation in Nanhaizi Park of Daxing District,continuously surveying PM_（2.5） concentration which distanced vegetation 1m,5m,15 m,30m,50 m,analyzing the influence of the distance away from vegetation acted PM_（2.5）concentration and its diurnal variation.The results showed that the variation of PM2.5concentration presented a trend of increase after the first reduce from morning till the night,and the minimum value of PM_（2.5）concentration occurred at 15：30,the maximum value occurred at 05：00—07：00;with the distance away from vegetation increasing,PM_（2.5）concentration firstly reduced firstly and then slowly increased,and the minimum value occurred at the place which distanced vegetation30 m,simultaneously the forests had the strongest adsorption ability for particulate matters.
