英文摘要	Two mathematical models of the Laptev and East Siberian s eas coastal dynamics - multifactor model and multiplicative phenomenological model - have been developed and used for evaluation of the ice-rich coast degradation rate during the Holocene. Thermo-erosion aff ecting ice-rich coasts occurred most intensely in the Holocene during the Subboreal period (from 10 to 20 m/year) and in the Early Middle Ages (8-15 m/year). Over 500 years BP the average retreat rate of the cryogenic coasts most of the time had not exceeded 2 to 6 m/year. However, it has drastically increased to 8-19 m/year in the last 40 years. Contemporary climatic conditions and retreat rates of ice-rich coasts have been found to be close to those existing during the Atlantic and Subboreal optimums of the second half of Holocene, when the mean air temperature anomalies had reached 2 °C and more during the thawing season (July through September), in the absence of multiyear ice in the Siberian seas.
