摘要 通过对宿迁学院内4种类型绿地和对照内空气PM2.5浓度及温度、湿度、风速、光照强度进行监测分析,结果表明:4种绿地类型及对照内空气PM2.5浓度日变化明显,基本都呈双波峰走势,分布在上午9:00和下午13:00;4种绿地类型及对照内空气PM2.5浓度均值按大小排序为:对照点>高羊茅草坪>火棘+海桐—高羊茅>黄山栾树+白玉兰—金钟花+迎春—高羊茅>日本早樱—狗牙根;空气PM2.5浓度与4种类型绿地的温度都达显著正相关,与光照强度达到极显著正相关。 Air PM2.5 concentration and temperature, humidity, wind speed and light intensity in tour types ot green space and the control in Suqian College were monitored and analysed. The results showed that PM2.5 concentration in four types of green space and the control changed significantly with dual wave movements, distributing in 9 : 00 and 13 : 00pro ; PM2.5 concentration sorted by size as follows : Control Points 〉 tall rescue turf 〉 Pyrucantha+Pittospo- rum-Tall fescue 〉 Huangshan Koelreuteria+Magnolia-Admiralty+Spring Flower-tall 〉 Japan early cherry-Bermu- dagrass ; PM2.5 concentrations and temperatures of four types of green space reached a significant positive correla- tion, highly significant positive correlation with the light intensity.
