为揭示斑块型城市森林公园空气颗粒物浓度的时空变化规律，于2018年旱季和2019年雨季，通过长期连续固定监测方法，对石门国家森林公园花海、湖心岛、竹林、国际森林浴场4种生境颗粒物进行了监测和评价。结果表明，空气颗粒物各项指标均为旱季＞雨季，TSP、PM10 平均浓度在各监测点排序为花海＞竹林＞湖心岛＞森林浴场，PM2.5平均浓度排序为花海＞湖心岛＞竹林＞森林浴场。各监测点TSP、PM10、PM2.5等级均在“Ⅱ”以上，未达到污染水平，因此，空气颗粒物指标对森林康养、森林旅游等活动的时间和地点均无限制。

In order to reveal the temporal and spatial variation of particulate concentration in patch urban forest park,in dry season of 2018 and rainy season of 2019,the particulate matter in four habitats of Shimen National Forest Park,namely flower sea,lake island,bamboo forest and international forest bathing place,was monitored and evaluated by means of long-term and continuous monitoring.The results showed that all the indexes of air particulate matter in dry season were higher than that in rainy season.The average concentrations of TSP,PM10 and PM2.5 were ranked as the highest in the flower sea and the lowest in the forest bathing area.TSP,PM10 and PM2.5 levels of the monitoring in“Ⅱ”above,has yet to reach pollution level.Therefore, the air particulate index on forest health,forest tourism and other activities of time and place are unlimited.
