Abstract Fine particulate matter (PM ) has been paid more and more attention because of its negative effect on
2.5
human health. Previous studies have shown that green space has an effect on PM concentration, but it is not clear
2.5
whether this effect correlates with the spatial distribution of PM concentration. In addition, most of these studies
2.5
focus on the change of PM concentration in the interior of green space, and there is little research on the spillover
2.5
effect of green space. Based on the 2018 remote sensing images and PM raster data of urban districts in Hefei, the
2.5
study area was divided into three regions, namely HH (High-High) effect area, LL (Low-Low) effect area and
insignificant effect area through autocorrelation analysis of the spatial distribution of PM concentration. According
2.5
to the interpretation and selection of the green space, the research green spaces were obtained, PM raster data were
2.5
statistically analyzed by ArcGIS, and the correlation analysis and regression analysis were carried out by SPSS. The
results showed that the spillover effect of green spaces in different regions had different effects on PM
2.5
concentration. In HH effect area, the average concentration of PM decreased with the increase of the distance from
2.5
the green spaces, but it increased in LL effect area. The effect of green space index on the variation of PM
2.5
concentration was different in different regions, NDVI had the greatest effect on PM concentration in LL effect
g 2.5
area, while S had the greatest effect on PM concentration in HH effect area and insignificant effect area.
