- 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、50 m处的PM2.5浓度进行全天连续监测，分析远离林带不同距离对PM2.5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PM2.5日变化趋势相同，从早到晚均呈先降低后增加的趋势，PM2.5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PM2.5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30 m处PM2.5浓度达到最低值，说明森林对颗粒物的削减作用最强。
- Abstract:
- Selecting vegetation in Nanhaizi Park of Daxing District，continuously surveying PM2.5 concentration which distanced vegetation 1 m，5 m，15 m，30 m，50 m，analyzing the influence of the distance away from vegetation acted PM2.5 concentration and its diurnal variation.The results showed that the variation of PM2.5 concentration presented a trend of increase after the first reduce from morning till the night，and the minimum value of PM2.5 concentration occurred at 15:30，the maximum value occurred at 05:00—07:00；with the distance away from vegetation increasing，PM2.5 concentration firstly reduced firstly and then slowly increased，and the minimum value occurred at the place which distanced vegetation 30 m，simultaneously the forests had the strongest adsorption ability for particulate matters.
