摘　　要：垃圾填埋场对周边地质环境的污染越来越受到研究人员的重视,其影响因素复杂,不仅与MSW的性质有关,还与垃圾填埋场的类型及其所处地质环境有密切关系。为分析垃圾填埋场中的渗滤液、重金属以及其他有害物质对周边地质环境(地下水环境、土壤环境)的影响规律,对大量相关文献和实验资料进行研究分析。研究结果表明:渗滤液是垃圾填埋场影响周围地质环境最为重要的因素,对渗滤液污染地表水及地下水情况和防治方法进行了探讨;同样渗滤液也是重金属污染土壤的载体,重金属在土壤剖面中的滞留量一般随深度的增加而逐渐减少;重金属对土壤的污染具有积累性和滞后性特点,随着填埋时间的延长污染加重。最后,根据其污染途径和污染规律,提出了相应具体防治对策。The geological environment pollution around the landfill has been paid more and more attention.The influence factors are very complex,not only with the nature of MSW,but also the type of landfill,which is closely related to the geological environment.Lots of literatures and experimental data were studied and analyzed after field investigations.The results show that the landfill leachate is the most important factor that has impact on the surrounding geological environment and the mechanism and control methods are discussed for leachate pollution of surface water and groundwater pathways.On the other hand,the leachate is also the carrier of heavy metals for the contaminated soil.The remaining amount of heavy metals in the soil profile gradually decreased with the increase of depth;heavy metal pollution of soil has the characteristics of accumulation and lag;and increased pollution with the time going in the surrounding of the landfill.Finally,the specific control measures are proposed by their means of pollution and pollution laws.
