Review on Spatial Interpolation and Its Verification Method of Heavy Metal Pollution in Soil

This paper reviewed the research status of spatial interpolation methods for heavy metal pollution in soil, analyzed the advantages, disadvantages and application scope of three typical interpolation methods (deterministic interpolation method, geostatistical interpolation method and combined interpolation method) and two commonly used accuracy verification methods (cross validation method and independent data set validation method), put forward some future research directions, such as strengthening the optimization and accuracy improvement of combined interpolation model, using computer intelligent technology to optimize interpolation algorithm model, and developing a new model for mining spatial interpolation soft data in the field of soil heavy metals.
