Abstract：[Objectives] The content levels of heavy metals Cd, Hg, As, Pb, Cr, Cu, Ni and Zn in 208 surface soils in the study area were detected. The environmental baseline value of heavy metal elements and the accumulation of changes relative to background values were obtained in regional surface soil. Based on this, the disturbance degree of heavy metal elements in regional surface soil by human activities can be judged. [Methods] Standardized method and relative cumulative percentage statistical method were used to calculate the environmental baseline value and deviation of heavy metals in regional surface soil. The average environmental baseline values obtained by these two methods were taken as the environmental baseline values of heavy metals in the surface soil of the study area. [Results] The content levels of heavy metals Cd, Hg, As, Pb, Cr, Cu, Ni and Zn in the surface soil of the monitoring points in the study area were not exceed the risk screening values for soil contamination of agricultural land. The environmental baseline values of heavy metals Cd, Hg, As, Pb, Cr, Cu, Ni and Zn obtained by these two methods were 0.22 mg/kg, 0.09 mg/kg, 13.34 mg/kg, 30.7 mg/kg, 82.0 mg/kg, 29.7 mg/kg, 38.0 mg/kg and 89.1 mg/kg respectively. The relative deviation ranged from 0.5% to 12.0%. [Conclusions] The environmental quality was generally good of regional surface soil. Compared with the background value, the environmental baseline value increased in different degrees of heavy metals Cd、Hg、As、Pb、Cr、Cu、Ni、Zn in regional surface soil, but the change rate was less than 50%, and the increase was not significant. Among them, the cumulative index evaluation grade of Cd reached slight accumulation, while other heavy metals elements had no obvious accumulation. This shows that heavy metal elements in the surface soil of the study area have been disturbed by human factors to a certain extent, and the influence degree was slight.
