Abstract ：In order to improve the ecological environment of Pingyin County and provide geochemical
data and scientific basis for agricultural division, environmental protection and local disease
prevention and control, the authors carried out ecological geochemical survey in Pingyin County. 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, with the main elements being heavy metals. 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
like industrial soot, industrial sewage and domestic waste.
