摘要：Soil pollution caused by heavy metals was studied. The potential ecological risks posed by seven heavy metals (Cu, Pb, Cd, Cr, Ni, Zn, and As) in the agricultural soils of Yanggu, Shandong Province, China, were analyzed. The spatial variation of the seven heavy metals was used to develop a probability map of the heavy metals based on sequential simulation methods. The ecological risks to the region from the heavy metals were then assessed using the Hakanson potential danger index. The result showed that Cd was the main problem in the Yanggu area. The potential ecological risk from Cd was nearly 80 and the risk classification was medium. The total potential ecological risk from all seven heavy metals was 114.656. This indicated that heavy metal pollution in the entire study area posed only a slight ecological risk.
