| 中文摘要: |
| 在黄岛石油化工区周边采集土壤样品27个，测定土壤中As、Cd、Cr、Cu、Hg、Ni、Pb、Zn等元素，并运用统计分析、土壤质量综合指数法对测定结果做系统分析。结果表明，除As外，黄岛石油化工区周边土壤中Cd、Cu、Cr、Hg、Ni、Pb、Zn的测定均值均超过青岛市土壤背景值。Cd、Pb、Zn空间分布大体一致，测定值最高的地方均是离石油化工区最近的地方。Cr、Cu、Ni离石油化工区越远，测定值越低。而Hg则相反，离石油化工区越远测定值越高。黄岛石油化工区周边土壤不宜用作农用地，除1处不宜用作建设用地Ⅰ类外，其他均可作为建设用地Ⅰ类和Ⅱ类。 |

| 27 soil samples were collected around the petrochemical area in Huangdao to determine As，Cd，Cr，Cu，Hg，Ni，Pb，Zn, etc., the measured value was systematically analyzed by statistical analysis and comprehensive index of soil quality. The results showed that except As，the mean measured value of Cd，Cu，Cr，Hg，Ni，Pb，Zn in the soil surrounding Huangdao petrochemical area were above the soil background values of Qingdao. The spatial distribution of Cd，Pb and Zn was generally the same，and the places with the highest measured value were closest to the petrochemical area. The farther away from the petrochemical area，the lower the measured value of Cr，Cu and Ni. On the contrary，the farther away from the petrochemical area，the higher the measured value of Hg. The soil surrounding Huangdao petrochemical area was not suitable for agricultural use. Except for one place which was not suitable for use as class Ⅰ construction land，all the others could be used as class Ⅰ and Ⅱconstruction land. |
