| Abstract: | A model of DVI is built in this paper. The computation was conducted by near-infrared and red bands of SPOT 5 image and observed concentration of PM10 (inhalable particulate matter) to retrieve concentration of PM10 in SPOT 5 image of Beijing urban area acquired in 2007. It is shown that the spatial distribution trends of PM10 are basically identical between the retrieved result and the observed data. In 2007，PM10 pollution in northern part of Beijing urban area was more serious than that in southern part. The concentration of PM10 was relatively low near the greenbelt and water body，and was comparatively high around roads. |
