报告简介：In this presentation, two techniques for hotspot analysis including local index of spatial association (LISA) and Getis Ord Gi* are explored based on geochemical databases from Europe, London in the UK and Galway in Ireland. The LISA method can identify spatial clusters of high values and low values, as well as spatial outliers. On the other hand, the Getis Ord Gi* is effective to identify spatial clusters. In the big data era, such techniques play important roles in revealing patterns and special features hidden in environmental databases. Identification of soil pollution hotspots provides essential decision support for assessments of hazard, exposure and risks from soil pollution.
