Abstract

The fog probability in urban area is determined by the observatory data. Taking the regular grid to be the assessed unit, the Fragility Exponential (FE) is computed upon the gird cell, in which the density of the road-net is stood for, and the FE can be modified according to the important facility distributed on the grid cell. The population density is utilized as the index of vulnerability. Moreover, the probability, fragile, and vulnerability is composed by 5:2:1 to integrally measure the risk index of fog in urban area. The example use nearly 10 years observatory data of fog in Beijing district to assess the disaster’s risk by spatial grid. The result indicates that the high risk area is consistent to the extending of highway and ring-roads, as parts of urban center area and airport, and so on.
