摘　　要：通过分析大兴安岭南段森林沼泽景观地球化学特征，提出该类地区表生条件下元素迁移集散分布规律，Pb、As、Sb、Mn和部分Au、Mo富集于-4～＋40目、粒级的概率是46％～71％；Ag、Cu、Zn、Hg和部分Au富集于-4～＋60目的概率是46％～60％。据此，在矿调工作中制定出一套森林沼泽景观中地球化学工作方法与异常查证评价技术。By analyzing the geochemical characteristics of the forest swamp landscape in the southern section of Daxinganling, the paper proposes distribution law of element migration under supergene conditions in such areas： Pb, As, Sb, Mn and some Au, Mo enrichment at -4 to ＋40 mesh, and the probability of grain size was 46%- 71%; Ag, Cu, Zn, Hg and some Au enrichment at -4 to ＋60 mesh and 46% - 60% probability. This paper accordingly develops geochemical work methods and verification technology of anomaly evaluation during mineral survey in the forest and swamp landscape.
