摘　　要：本文选用污染损失率法初步估算了贵州兴仁煤矿废水灌溉区的土壤重金属污染损失率和重金属污染经济损失量。计算数据显示,环境污染所造成的经济损失约为339.58万元。研究区40%的土壤处于严重污染状态,呈现出R(As)>R(Cu)>R(Zn)>R(Pb)的关系,综合污染损失率与元素As的单元素污染损失率表现出极高的相关性,反映出As是造成研究区重金属污染的主要污染元素。This article chooses Pollution Loss Rate Method preliminary estimate the soil heavy metal pollution loss rate and heavy metal pollution economic loss of the identify mine drainage in Xinren,Guizhou.The results showed that economic losses of the environment pollution was about $3,395,800 and 40% soil in the study area was seriously polluted,and the single pollution lost rate of the soil heavy metals was in the order of AsCuZnPb.The comprehensive pollution loss rate showed high correlation with the single element pollution loss rate of As,and these also suggested that the As was the main pollution element which caused the heavy metal pollution in the study area.

关 键 词：煤矿废水灌溉区 重金属污染 污染损失率法 经济损失量
