摘要
Spatial interpolation played an important role in spatial distribution of heavy metals in soil and pollution assessment. Soil sample contaminated by Cu, Pb, Zn, Cd, As and Hg elements in Yicheng district, Hefei were collected and analyzed. The authors validated and appraised the representative spatial interpolation methods such as inverse distanced weighted (IDW), radial basis function (RBF) and ordinary kriging (Kriging). The results showed that Kriging exhibited best effect in Cu, Pb and As, IDW in Zn and RBF in Cd and Hg.
