ResumoInvestigation of arsenic content in black soil of Yushu city in Jilin province was carried out,and the affecting factors were analyzed.The results showed that arsenic content was higher than the background value of black soil,but it was lower than the environmental quality standard for soils.The variograms of arsenic persistently increased and could be fitted by exponential equation. Arsenic in soil layer of 20 cm had good spatial structures,and the accumulation areas of Arsenic were mainly farmland of suburb.There was no significant correlation between arsenic content and pH and the organic matter content in black soil due to the influence of anthropogenic activities.
