Abstract The exploration geochemical methods play an important role in northern Daxinganling region, which presents a typical swamp forest landscape. Although sharing the same natural environment in general, the local geology, geomorphology, development of vegetation and degree of weathering are various. This may influence the choice of working methods and their application effects. Based on the research of stream sediment and soil geochemical survey in 1:50000 scale and later verification, it is concluded that the Fukeshan area belongs to medium-low mountainous swamp forest landscape. Samples of stream sediment survey can adopt fine sand, powder sand and rock debris. The pretreating method for field samples is water sieve, with size fraction of-10 to+60 mesh for preliminary processing. Sampling is carried out in Horizon B for the secondary verification to 1:10000 pedogeochemistry survey. The samples are composed of mainly brown and earthy yellow soil, with preliminary processing size of-40 mesh, sorting after drying.
