In this paper, the authors carried out ecological geochemical survey in Pingyin County, Shandong Province. The results show that Pingyin County area and its west farmland have such anomalies as As, Ni, Cd, Cr, F, Cu, Mn, S and Hg. In Pingyin area, the soil anomalies are characterized by low anomalous contrast and low concentration coefficients, whereas in west farmland, the main anomaly components are As and Cd, and the element content is remarkably related to major elements of SiO₂, Al₂O₃, Fe₂O₃, being negatively related to SiO₂, and positively related to Al₂O₃ and Fe₂O₃. All these characteristics suggest that the major elements in soil and the soil texture are main factors causing anomalies. In contrast, the anomalies in Pingyin County are mainly anomalies of S, Hg, As, Zn and Mn, which are evidently caused by human composite pollutions.
