Abstract. Electrometric methods are widely used in modern soil science and ecology. The electrical resistivity can be used as a physical characteristic of the soil itself and its genetic horizons. This paper describes the transect-catena soils in the Lake Baikal coast area at the Bol’shye Koty Bay - a model territory for environmental monitoring of biota and interstitial waters qualitative characteristics for Limnological Institute SB RAS. The terrigenous material supplied to the Lake Baikal splash zone is determined of soils as a central component of the terrestrial and aquatic systems. The detailed electrical resistivity analysis of 3 soil types (brown soil, litozem, stratozem) is presented. Features of the electrical resistivity distribution in studied soil profiles are ambiguous by gradually decreasing and increasing, to the complicated multimodal. Attracting by the mesomorfology and genesis data of individual horizons studied soil allowed to their grouping with different values of the electrical resistivity, which depend on the impact pyrogenesis, degree of weathering of the parent rocks and their age. The results of soil investigations in a context of the electrical and mesomorfology features, in our opinion, may be the basis for rapid diagnosis of the terrigenous material arriving in the Lake Baikal splash zone.
Keywords: electrical resistivity of soils, soil mesomorphology, pyrogenesis, environmental monitoring, splash zone, Lake Baikal.
