摘要

The research about the content of soil element in Ngari is still in its infancy,and there lacks systemic research and discussion. The 90 topsoil samples were selected from the 7 counties in Ngari area,and 13 elements were investigated systematically. The correlation analysis method and factor analysis method were used to study the interrelationship and accumulating,migrating and transforming rules of the selected 13 elements.The results showed that there was significant correlation among most of the transition elements in the topsoil. The main factors,which influenced the element content,were nature factors. Human activities also had certain effect on the element content of surface soil,but the strength was weak.
