///Geochemical baseline values of elements mean their normal concentrations within the natural environmental soils and belong to a kind of inherent chemical compositions and structural characteristics related to primitive matter. Some conclusions have been reached: 1) most element contents are not in normal distribution, and the mean content from these elements does not change obviously after eliminating abnormal data; 2) anthropogenic input has apparently increased a part of contents of Cd, Hg, Se and N, etc. in topsoil above the depth of 20 cm; and 3) parent matter, genetic classification of soils and topographic units are main factors affecting element content distribution within soil of Jiangsu, and the difference of normal concentrations of some elements are very obvious in soil of different areas. The information obtained by the authors will provide new clues and bases for assessing eco-environmental quality and establishing local standard of soil environment.
