Реферат:	eng: The bottom sediments were studied as a source material for the mathematical treatment. 10 geochemical parameters: Ca, Ti, Mn, Fe, Br, Br / Rb, Br / Sr, Br / Y, Co / Inc, Sr / Rb were considered. The elements content were measured by X-ray fluorescence analysis on synchrotron radiation (SR XRF, BINP) along the entire length of the sediment core (1974 mm) with 1mm step. Matrix of the geochemical time series was built taking into account continuous sedimentation at an average accumulation rate of 1.06 mm/year in the time interval AD 530-2010 years. Reconstruction of target parameters (temperature, precipitation and 'climate type', lake level) made by three methods - regression, discrimination and nearest neighbor realizing different approaches to the problem to be solved. ©, 2014, SGEM2014.
