Abstract: Based on the soil geochemical data obtained during the agricultural geo-environmental survey of Zhejiang Province and the basic conception of geochemical background values,the soil geochemical baseline was divided into 13 statistical units in light of types of soil parent materials.The three major agricultural regions of Zhejiang Province were fixed as statistical units for soil environmental background values.After repeatedly crossing out anomalous values,mean values,standard deviations and variation coefficients of 52 elements(or oxides) were obtained,and may be cited as major geochemical data for formulation of regional soil environmental quality standards,and evaluation and remediation of soil pollution.
