Abstract

Based on geochemical investigation of land quality in northern Muchuan County of Sichuan Province, the authors identified the geochemical characteristics of Se element in the soil of the working area and carried out a study of its causes . The results show that the Se content of the soil in the working area ranges from 0.06×10^-6 to 1.49×10^-6, with an average value of 0.41×10^-6. It is mainly dominated by selenium-enriched soil, which satisfies the conditions of selenium-enriched soil and possesses 60% of the whole working area. The content of Se in different parent rocks is quite different and tends to be enriched in the surface layer. The content of Se in soils with Xiangxi Group as the parent rock is higher but the content of heavy metals is lower; the content of Se is the highest in forest land in different land use types; the difference in content of Se in different soil types is relatively small. Correlation analysis shows that the Se content of the soil is significantly positively correlated with SOM, Pb, As, Cd, etc. Different parent rocks have a greater influence on the correlation between Se content and pH, indicating that the main factors of Se content in soil are parent rocks, SOM and heavy metal elements in the working area.

Key words： Se content in soil geochemical characteristics genesis analysis Xiangxi group Muchuan County
