| 摘 要： | 采用漠河县洛古河采金场作为样地对土壤重金属进行分析测定,并选取李金镛祠堂后山的土壤作为该地区的土壤背景值,对其含量做分析测定.采用单因子指数法、内梅罗综合污染指数法对该采金场土壤进行评价,结果表明该地区土壤中受到了As的轻度污染.由于该地区属于寒温带针叶林区,土壤中的重金属会对植被生长产生影响[9],更可能给开采过后的生态恢复带来巨大的困难,所以对该地进行重金属污染调查和评价具有重要的意义.

| Abstract: | Regard the soil of LuoGu River gold placer-mining in MoHe country as the sample,and soil of LiJinYong imperical court back-hill as the background,both contents of heavy metals are analyzed.The single factor index and Nemerow integrated index are used to assess the heavy metals of the gold placer-mining location.The results show that the area is polluted with the heavy metal As lightly.In addition,while the area is belong to the cool-temperate zone conifer forests,the heavy metal may influence the growth of plants,furthermore may bring a great difficulty to restoration.So it is important to assess and investigate the heavy metals of the area. |
