| Abstract: | In order to meet the requirements of environmental assessment and metallogenic anomaly identification based on topsoil and deepsoil,the Resources and Environmental Assessment Information System based on soil geochemistry data has been developed independently.The system integrated the Inverse Distance Weighted interpolation model and geostatistics models which contain robust variograms.Based on this,the nonlinear multifractal interpolation method also has been introduced in this system.Meanwhile the system a... |
