摘要: 为了研究黄河口国家公园湿地土壤污染状况和生态风险,沿黄河故道东营段、 黄河入海口以及沿海处共设20个采样点进行土壤采集,对铅、 镉、 铬、 铜、 锌、 镍、 汞、 砷8种重金属含量进行检测,并利用综合污染指数法、 地累积指数法和潜在生态风险指数法进行土壤污染评价。结果表明: 研究区铅、 镉、 铬、 铜、 锌、 镍、 汞、 砷元素的质量比分别为16.4、 0.11、 57.3、 14.0、 46.9、 20.0、 0.014、 7.71 mg/kg,均符合农用地土壤污染风险管控标准要求;研究区土壤综合污染指数为0.57,地累积指数为-0.23,潜在生态风险指数为65.54,表明研究区属于无污染土壤,存在轻微潜在生态风险。

Abstract: To study the soil pollution status and ecological risk of the wetland in the Yellow River Estuary National Park, a total of 20 sampling points were set up along the Dongying section of the old Yellow River course, the mouth of the Yellow River and the coastal areas for soil collection, and the content of Pb, Cd, Cr, Cu, Zn, Ni, Hg and As were detected. Soil pollution was evaluated by comprehensive pollution index,groundaccumulationindexandpotential ecological risk index.The results show that the mass ratios of Pb, Cd, Cr, Cu, Zn, Ni, Hg and As in the study area are 16.4, 0.11, 57.3, 14.0, 46.9, 20.0, 0.014, 7.71 mg/kg respectively, which all meet the risk control standards for agricultural land soil pollution. The integrated soil contamination index of the study area is 0.57, the land accumulation index is -0.23, and the potential ecological risk index is 65.54, indicating that the study area is a non-polluted soil with a slight potential ecological risk.
Keywords: soil pollution; heavy mental; comprehensive pollution index; geological accumulation index; potential ecological risk assessment; the Yellow River Estuary National Park

黄河三角洲湿地位于山东省境内,因地理位置优越而形成了特殊的湿地生态系统,在推进我国实施人与土地生态系统的协调发展政策方面发挥重要作用[1]。黄河入海口承接了整个黄河流域输送来的物质流、 能量流和生态流,在河、 海、 陆交互作用下形成了世界上独一无二的河口三角洲,孕育了我国暖温带最典型的河口湿地生态系统。……
