摘　　要：查明长江沿岸带黄石段土壤的重金属元素分布特征及环境质量情况,是制订该区土壤污染防治对策的基础。以研究区表层土壤(0~20 cm)为研究对象,测定Zn、Ni、Cd、Cu、Cr、Pb、As、Hg等8种重金属元素的含量,基于一类建设用地土壤污染风险筛选值,利用单因子指数法和内梅罗综合指数法评价土壤环境质量。测试结果显示,长江沿岸带黄石段土壤中上述8种重金属元素含量分别为69.52~1996.95、16.16~113.05、0.009~36.81、21.49~534.72、44.24~278.43、26.50~795.18、7.18~119.12μg/g和57.30~606.50 ng/g。评价结果显示长江沿岸带黄石段大部分地区(占比82.28%)的土壤环境质量为优良,黄石码头—西塞山码头一带(占比17.72%)的土壤环境质量为一般。建议在黄石码头—西塞山码头一带开展以预防措施为主的土壤污染防治工作。Identifying the distribution characteristics and environmental quality of heavy metal elements in Huangshi section of the Yangtze River coasal zone is the basis for formulating soil pollution prevention and control measures in this area.Taking the surface soil(0~20 cm)of the study area as the research object,the contents of 8 heavy metal elements such as Zn,Ni,Cd,Cu,Cr,Pb,As and Hg are determined.The single-factor index method and Nemerow integrated index method are used to evaluate the soil environmental quality.The test results show that the contents of the above eight heavy metal elements in the soil are 69.52~1996.95,16.16~113.05,0.009~36.81,21.49~534.72,44.24~278.43,26.50~795.18,7.18~119.12μg/g,57.30~606.50 ng/g,respectively.The evaluation results show that the soil environmental quality in most areas of the Huangshi section of the Yangtze River coastal zone(accounting for 82.28%)is good,and the soil environmental quality in Huangshi Wharf-Xisashan Wharf area(accounting for 17.72%)is general.Soil control based on preventive measures is recommended for the latter.
