| 摘 要： | 以山西省永济市耕地为研究区域,通过收集整理土壤环境质量样点数据,运用GIS技术建立了土壤环境质量数据库,依据国家土壤环境质量评价标准进行分析评价,获得了永济市耕地土壤环境质量评价结果.土壤面源污染水、土综合评价结果表明:18个样点中有3个为无污染,11个为轻度污染,4个为中度污染.点源污染土壤综合评价结果表明:该区主要污染物为F、Cl、Pb、Cd、As及DDT.蔬菜地样点综合评价表明:大部分蔬菜生产符合绿色食品种植要求(NY/T391-2000)和无公害食品蔬菜地种植要求(NY5010-2001);在不符合要求的样点中,超标物主要是Cd、Pb、Hg、As及DDT.该研究为进一步加强土壤环境质量管理与修复决策奠定了基础. |

| Abstract: | Based on the soil environmental quality data collected through sampling and the soil environmental quality database established with the aid of GIS, the farmlands of Yongji City, Shanxi Province, were appraised by referring to the national criteria for evaluation of soil environmental quality. Results showed that among 18 sampling sites, 3 sites were not polluted yet,11 slightly polluted, and 4 moderately polluted, and that main pollutants in the region were F, Cl, Pb, Cd, As and DDT. Most of the vegetable fields met the criteria of NY/T391-2000 for production of green food and NY5010-2001 for production of hazard-free food and Cd, Pb, Hg, As and DDT were main pollutants in the sampling sites that fell short of the standard. The findings of the research has laid down a foundation for further strengthening soil environmental quality management and decision-making for remediation. |
