ELECTROPHYSICAL METHOD IN THE SOILS DIAGNOSIS OF THE LAKE BAIKAL ENVIRONMENTAL MONITORING ZONE
Electrometric methods are widely used in modern soil science and ecology. The electrical resistivity can be used as a physicalcharacteristic of the soil itself and its genetic horizons. This paper describes the transect-catena soils in the Lake Baikalcoast area at the Bol’shye Koty Bay - a model territory for environmental monitoring of biota and interstitial waters qualitativecharacteristics for Limnological Institute SB RAS. The terrigenous material supplied to the Lake Baikal splash zone is determinedof soils as a central component of the terrestrial and aquatic systems. The detailed electrical resistivity analysis of 3 soiltypes (brown soil, litozem, stratozem) is presented. Features of the electrical resistivity distribution in studied soil profiles areambiguous by gradually decreasing and increasing, to the complicated multimodal. Attracting by the mesomorfology and genesisdata of individual horizons studied soil allowed to their grouping with different values of the electrical resistivity, whichdepend on the impact pyrogenesis, degree of weathering of the parent rocks and their age. The results of soil investigations ina context of the electrical and mesomorfology features, in our opinion, may be the basis for rapid diagnosis of the terrigenousmaterial arriving in the Lake Baikal splash zone.
