Abstract

The criterion system for a complex estimation of the economic and geoecological state of the coasts, their resistance to possible natural and man-made impacts is presented and tested in the paper on examples of Sakhalin and Iturup islands. This criterion system takes into account both the current state of the seacoasts and their past and forecasted variability. For complex estimation of the coasts’ state by proposed criterion system coastal sections with different geographical characteristics, intensity and types of economic use were selected. The estimation showed that the natural variability of geosystems and their high susceptibility to natural threats create the greatest difficulty for the economic use of selected coast sections. The probability of largescale actions’ carrying out to increase the coastline resilience to natural threats is low. Natural features of coastal landscapes, combined with a relatively low population density and small number of economic sites in the analyzed area, as a rule, do not lead to insoluble inter-industry contradiction. Recommendations about the feasibility of the type of economic use for coast sector are given based on the complex estimation fulfilled.
