Abstract: The Greater Khingan Mountains forest belt is an important area in the ecological security pattern of Two Barriers and Three Belts in China. Songling area in the northern part of the Greater Khingan Mountains is currently a blank area for ecogeological survey. Exploring the content and spatial distribution pattern of soil elements can provide basic support for ecological protection and restoration in the study area. In this paper, based on the multi-purpose regional geochemical survey and analysis method, the authors discussed the geochemical characteristics and distribution patterns of each element index in surface and deep soils of Songling area. From the perspective of the elements distribution patterns, the content of total C, N, P and S in the surface soil was significantly higher, while the content of K₂O, CaO, Na₂O and SiO₂ in the surface soil was significantly lower. The distribution positions of F, Cl, Br and I in the high value areas of the surface soil were mainly affected by the deep soil, and the enrichment of Br and I in surface soil was closely related to organic matter. As, Cd, Hg, Ni, Pb, Zn and other heavy metal elements in the soil slightly exceeded the standard according to the Nemerow comprehensive index.
