济南市PM2.5时空分布特征及其与土地利用的相关性研究

Temporal and spatial distribution characteristics and the correlation with land use of PM2.5 in Jinan City

文中以2018年济南市8个国控点PM2.5浓度实时监测数据和Landsat OLI遥感影像为数据源,探究济南市PM2.5的时空分布特征及与土地利用现状的关系。结果表明:2018年济南市PM2.5季度浓度夏季最低,冬季最高,西部的PM2.5浓度明显高于东部,除建设用地之外的地类均与年均PM2.5呈现负相关。

In this paper,taking the real-time monitoring data of PM2.5 concentration at 8 national control points in Jinan City and Landsat OLI remote sensing images as data sources,the temporal and the spatial distribution characteristics of PM2.5 and the relationship between PM2.5 concentration and land use status in Jinan City were explored.The results showed that PM2.5 concentration in Jinan was the lowest in summer and the highest in winter in 2018.The PM2.5 concentration in the west was significantly higher than that in the east,and the land types except construction land were negatively correlated with the annual average PM2.5.
