This paper evaluated the social service value of wetlands in 2007, in Beijing, China. Remote sensing and GIS technologies were applied to perform data preparation and processing in combination with extensive field work. The social services of wetland include water supply, recreational opportunity, and raw material supply. The results showed that significant values come from water supply, which was...
To identify the inhalable particle matter (IPM) sources and to estimate the variability in their contributions to inhalable particle concentrations across the Beijing city, the spatial distribution of PM0.3, PM1.0 and PM3.0 concentration are simulated by monitoring data obtained from 93 air sampling stations in Beijing urban city and Kriging techniques. Inhalable particles in this study had aerodynamic...
