摘　　要：通过在拉萨市垃圾填埋场周边布设4个监测井,于2017—2018年采样分析24项地下水水质指标,并运用单因子指数、综合评价法、污染指数Pki法、等标污染负荷比法等对地下水污染状况进行评价。结果表明:地下水水质在良好—优良范围内;单项污染指数>1的有pH值、铅,相比背景井地下水水质有所下降;填埋场周边地下水污染程度呈轻污染,主要受到影响的指标为pH值、高锰酸盐指数、阴离子表面活性剂、铅、氟化物。24 groundwater quality indexes were analyzed in the samples from 4 monitoring wells around the landfill in Lhasa from 2017 to 2018. The groundwater pollution was evaluated by single factor index method, comprehensive evaluation method, pollution index Pki method and equal standard pollution load ratio method. The results showed that the groundwater quality was within good to excellent level. Single pollution index of pH value and Pb were greater than 1. The groundwater quality declined compared to that in the background well. The groundwater around the landfill was slight polluted. The main pollution targets were pH value, permanganate index, anionic surfactant, lead and fluoride.
