Tracing of heavy metal pollution sources is a current hot issue of agricultural soil quality management. Land utilization is one of the important factors which affect the heavy metal contents of regional soil. In order to model the relationship between soil heavy metal contamination and land utilization, this paper adopts a novel positive and negative association rule method in order to effectively...
The spatial distributions of soil heavy metals are not continuous with landscape heterogeneity. In the context, the existing spatial interpolation methods cannot obtain accurate estimation of contents of soil heavy metals in unknown locations. In this paper, we present a novel adaptive algorithm for spatial interpolation of soil heavy metals under spatial heterogeneity background. The core idea of...
