摘要： PM2.5污染已逐渐成为当前我国城市和区域首要的大气污染物,而包头市作为中国重要的工业基础基地,其PM2.5污染也较严重。以实地测量和遥感手段相结合的方法,通过PM2.5浓度数据和包头市Landsat 8 OLI影像数据,对包头市典型城市绿地及周边道路和小区PM2.5浓度进行了对比分析,完成了NDVI与PM2.5之间的相关分析。结果表明:劳动公园、赛汗塔拉和师院小树林PM2.5浓度比周边道路和小区相对较高,儿童乐园、青山公园和八一公园院内比周边稍低或相当,而NDVI和PM2.5浓度之间形成微弱的负相关关系。总体而言,城市绿地对PM2.5起到一定消减作用,而园内湿度大、树林郁闭度高、风速小和烟尘是引起公园绿地PM2.5浓度高的主要因素。

Abstract: PM2.5 pollution has gradually become as the primary air pollutants over urban and regional areas in China.Baotou City is an important industrial base in China,and its PM2.5 pollution is serious.Based on the combination of field measurement and remote sensing means,the values of PM2.5 concentration over the typical urban green spaces in Baotou City and the surrounding roads and districts were compared and analyzed using the measured PM2.5 concentration data and Landsat 8 OLI image data,and the correlation analysis between NDVI and PM2.5 concentration was carried out.The results showed that the values of PM2.5 concentration over the Labor Park,Sai han Tara Ecological Park and Teachers’ College Grove were higher than that over the surrounding roads and the districts,those over the Children’s Park,Qingshan Park and Bayi Park were slightly lower or similar to those over the peripheral regions,and there was a weak negative correlation between NDVI and PM2.5 concentration.On the whole,the urban green spaces play a certain role in reducing the PM2.5 concentration.The high values of PM2.5 concentration over the urban green spaces was mainly caused by the high humidity,high canopy closure,low wind speed and dust emission.
