摘  要:
Soil samples were collected from Weinan area to study the content and space distribution of rubidium(Rb),strontium(Sr) and zirconium(Zr).Results showed that average content of Rb in soil in Weinan was 76.76 ng/kg,which was higher in central-north area than in east-west area,and showed an increasing trend from south to north.Average concentration of Sr in soil was 172.02 ng/kg,which was the highest in north area,low in east and west area,and decreased from central area to south and north area.The average Sr content in Pucheng county was up to 204.30 ng/kg.Average concentration of Zr in soil was 172.20 ng/kg;the difference among areas was not significant.
