摘  要:
在2014年夏季,通过对宿迁市不同结构绿地和对照内空气PM2.5浓度以及温度、湿度、光照强度、风速进行监测分析。结果表明,不同结构绿地及对照内空气PM2.5浓度日变化均明显,基本呈现"M"型趋势,波峰出现的时间受人流和车流影响;PM2.5浓度均值从大到小的顺序是对照、草坪、篱草、大阔叶乔草、乔灌草、针叶乔草、小阔叶乔草;PM2.5浓度与不同结构绿地的光照强度达到显著正相关,与风速相关性不明显。

摘  要:
Relationships between PM2.5 concentrations in different green spaces and climate factors(such as temperature,humidity,illumination intensity,and wind speed)in the summer of 2014 in Suqian of Jiangsu Province were analyzed.The results suggested that the PM2.5 concentrations of 6green spaces and the control(without green covers)all changed obviously during the day,basically presented a "Mshape"trend,the appearance of peak concentration time were affected by the flows of people and vehicles.The average PM2.5 concentrations in different green spaces were in an order of from high to low the control,lawn,hedgerow,large broad-leaved herb,arbor-shrub-herb,conifer-herb,and small tree-herb.There was a significantly positive relationship between PM2.5 concentration and the illumination intensities of different green spaces,however,the correlation between PM2.5 and wind speed was not significant.
