摘要
铅锌矿区土地根据其利用情况分为自然地、菜园地和稻田,项目研究区各类型用地土壤中铅、锌、铜元素,均高于湖南省表土背景值,具明显累积特征,铅、锌、镉元素富集系数值由高到低依次为自然地土壤、菜园地土壤、稻田土壤。各类型用地土壤中铅、锌、铜、镉元素累积含量与铅锌矿区尾砂、废水及用地灌溉方式密切相关。
The land in lead-zinc mine area is divided into natural land,vegetable garden land and paddy field according to its utilization.The contents of lead,zinc and copper in the soil of various types of land in the project study area are higher than that of background value of Hunan’s topsoil,showing obvious accumulation characteristics.The enrichment coefficient values of lead,zinc and cadmium from low to high are natural soil,vegetable garden soil and paddy soil.The contents of Pb,Zn,Cu and Cd in soils of different types of land use are closely related with tailings,wastewater and irrigation methods of land use in lead-zinc mine area.
