摘　　要：本文以北方干旱地区的某非正规垃圾填埋场为研究对象,通过调查垃圾填埋区域及周边土壤性质,分析非正规垃圾填埋对土壤影响的特性。研究结果表明:该地区非正规垃圾填埋场椎体对其土壤环境影响较小,垃圾填埋场内土壤中大部分重金属含量随土层深度增加而降低,表明垃圾堆放过程未对底层土壤造成明显影响;填埋场内及周边土壤内梅罗污染指数评价等级为安全。This paper takes an informal waste landfill in the northern arid area as the research object,and analyzes the characteristics of the impact of informal waste landfill on the soil by investigating the soil properties of the landfill area and its surrounding areas.The results show that the cone of the informal landfill in this area has little impact on the soil environment,and the content of most heavy metals in the soil of the landfill decreases with the increase of the depth of the soil layer,indicating that the waste stacking process has no significant impact on the underlying soil;The assessment level of Merlot pollution index in and around the landfill site is safe.
