摘要
The authors analyzed the inhomogeneous distribution of soil element content based on new data of soil element content by 1∶250 000 regional eco-geochemical investigations in Jiangsu Province. The results showed that the soil in the province could be divided into three geochemical areas respectively named by alkaline-earth-elements enriched soil region in northern Jiangsu Province (normally pH>8.0), Cd-TOC-Mg-Zn enriched soil region along Yangtze River (normally pH >7.5), Si-B enriched soil region in Southern Jiangsu Province(normally pH <6.5), three geochemical areas and twenty four geochemical sub-areas were planned, and further studies indicated some special usage for some geochemical sub-areas.
