摘　　要：以海南省某市县2座非正规垃圾填埋场的生活垃圾筛分腐殖土为研究对象,通过对标检测样品的重金属含量、比较和分析了垃圾场周边土壤和腐殖土的重金属含量特征,研究了非正规垃圾填埋场的重金属来源。结果表明:2座非正规垃圾填埋场的腐殖土中重金属含量均低于标准限值,可用于园林绿化、苗圃栽培基质或就地与清洁土混合制备成种植土回填于场地;2座非正规垃圾填埋场的腐殖土重金属含量水平与垃圾场周边环境土壤重金属含量水平相关性较小,腐殖土中的铜、锌、镉、铅含量容易受到垃圾堆体组分的影响。In this paper,domestic waste screening humus in two informal landfill sites in a city and county of Hainan Province was taken as the research object.Heavy metal content in samples was detected by benchmarking,and heavy metal content characteristics of soil and humus around the landfill were compared and analyzed to study the sources of heavy metals in informal landfill sites.The heavy metal content in humus soil of the two informal landfill sites is lower than the standard limit,which can be used for gardening,nursery cultivation substrate or on site mixed with clean soil to prepare planting soil for backfilling.The content of heavy metals in humus in two informal landfill sites has little correlation with the content of heavy metals in the soil surrounding the landfill site,and the content of copper,zinc,cadmium and lead in humus is easily affected by the composition of the landfill body.
