[Objective] The characteristics of heavy metal content in paddy soil at Qianjiangyuan National Park were explored, and its pollution level was assessed. The sources of heavy metals were analyzed, and the associated human health risks were evaluated, in order to provide a reference basis for the prevention and control of soil heavy metal pollution and soil protection. [Methods] The pH value and contents of heavy metals, including Cd, Pb, Hg, Cr, As, Ni, Cu, and Zn, of 61 soil samples were determined. Index, factor and cluster analyses were employed to assess the characteristics of and ecological risks posed by the heavy metal pollution, analyze their sources, and evaluate human health risks. [Results] ① The surface soil of the paddy fields was acidic. The average Cd, Pb, Hg, Cr, As, Ni, Cu, and Zn contents were 0.19, 32.74, 0.13, 67.06, 4.43, 24.90, 21.51, and 94.60 mg/kg, respectively. The average contents of Hg, Cr, Ni, Cu, and Zn exceeded the Zhejiang provincial soil background values by 1.32, 1.71, 2, 1.19, and 1.13 times, respectively. ② The average contents of the eight heavy metals were lower than the corresponding risk screening values for agricultural land soil, as represented by the average heavy metal content in the paddy fields. The exceedance rates of sampling points for Cd, Ni, and Cr were 6.56%, 3.28%, and 1.64%, respectively. ③ The results of factor analysis and the other methods showed that the soil heavy metal sources were predominantly anthropogenic and were the result of a combination of human and natural influences. The overall carcinogenic health risk for children was deemed tolerable. [Conclusion] The level of heavy metal pollution in the paddy soil at Qianjiangyuan National Park was low, as was the overall ecological risk. However, pollution risks were associated with Cr and Ni. The heavy metal As is the primary carcinogenic factor affecting human health.
