| 摘 要： | 土壤环境质量评价是了解土壤环境质量状况、采取保护措施的重要前提,本文用土壤环境质量标准(GB15618-1995),对河北平原表层土壤重金属环境质量进行了评价,结果表明:河北平原表层土壤环境质量优良,一、二级土壤分别占全区93.02%和6.62%。同时又根据重金属元素的环境地球化学行为,采用富集因子,有效地区分了重金属污染的自然影响和人为影响,结果显示,河北平原表层土壤人为污染的面积较大,但以轻微污染为主。

| Abstract: | Soil environmental quality assessment is an important prerequisite for understanding its current status and carrying out environmental protection.The authors made an evaluation of environmental quality of heavy metals in topsoil of Hebei plain based on Environmental Quality Standard for Soils(GB15618-1995),and the results show that the quality is excellent,with the area that comes up to the first grade standard being 93.02% and up to the second being 6.62%.Making use of environmental geochemical behaviors o... |
