Abstract: Multi-objective regional geochemical survey in Cangzhou-Wuqiang area in Hebei Plain, China discovered As, Cu, Zn, Fe, Mn, Si, Ti and other elements as the representative of multi-element geochemical anomalies. In this paper, the abnormal causes, effects and other ecological problems were interpreted and evaluated by t geochemical methods. Results show that the special sedimentary geological environment, namely the adsorption of natural lowland plains region is the main reason for large-scale geochemical anomalies.

Key words: Hebei Plain；soil；geochemical abnormity; sedimentary environment
