摘　　要：利用土壤重金属元素环境质量矿物学评价方法,对浙江省全境土壤中不同土壤类型(或亚类)表层、不同母质表层和剖面中的Pb进行环境质量评价的结果表明,土壤中Pb的实测量和土壤对Pb的固持量决定了土壤中Pb的环境质量,浙江省土壤中Pb的污染度有正负值,说明土壤中的Pb对有些地区产生了污染,而对有些地区则没有产生污染。研究结果揭示,土壤矿物对Pb具有一定的固定与容纳能力,超过其固定与容纳能力,土壤中的Pb会对环境造成污染。这一旨在揭示土壤中重金属元素与各种矿物之间环境平衡关系的方法,可为评价土壤环境质量提供科学依据和技术支撑。Using mineralogical method for evaluating environmental quality of heavy metals in soils, this paper evaluates Pb element environmental quality of surface layer of different soil types/subtypes and of surface layer and section of different parent material types in all Zhejiang Province. The evaluation indicates that Pb environmental quality of soils is decided by survey value and adsorption content of Pb. The environmental capacity of Pb was very high in soil of Zhejiang Province. However, the positive and negative value of the Pb contamination reflects that content of Pb does not produces contamination in some areas while causing pollution in certain areas. The analysis results reflect that soil minerals are rather capable of fixing and carrying Pb element, but the exceeding of this capacity will pollute the surface and underground water.
