Spatial Distribution Characteristics of Urban Dust Pb Element Based on Conditional Gaussian Simulation
Urban dust, which is of surface solid particles scattering in different districts of urban( location and functional districts) . More and more people concerned about the urban environment pollution caused by the Urban dust, Especially the harm of urban living environment caused by the urban dust of heavy metals. This pape main using the Gstsat package of R software to 500 conditional Gaussian simulation the Jinhua City of the PB element,and stochastically extracts three simulations to carry on the a-nalysis to its simulation results, from the simulation results can be seen the Pb element in the study area showed the same trend of spatial variation, but in detail the spatial variation is discriminating, the simulated value was uncertain for the unobserved point, to overcome the smoothing effect of ordinary kriging method,can be better reflect the randomness and structural of the study area.
