Abstract Based on the 1258 shallow groundwater samples of Dongting Lake region, the spatial distribution of Eh was analyzed by geostatistical method, and the redox zoning of groundwater system in the lake region was carried out by using the concentration spatial data of redox sensitive indexes. The results show that, controlled by geological structure, stratigraphic lithology, swamp wetland and paddy field, spatial distribution of Eh in Dongting Lake region shows a decreasing trend from hilly areas to the hinterland of the lake, which reflects a fact that, groundwater environment gradually changes from relative oxidation to relative reduction. Groundwater system in Dongting Lake area can be divided into three redox zones, which arestable and reductive zone, manganese (IV) reductive zone and iron (III) reductive zone. In general, the three zones reflect the spatial distribution of Eh well, although the zones and Eh are not in synchronizationin some regions for Mn enrichment in aquifer media.
