АНТРОПОГЕННЫЕ ИЗМЕНЕНИЯ РЕЛЬЕФА ГРУЗИИ И ПРОГНОЗ НА БЛИЖАЙШЕЕ БУДУЩЕЕ

Аннотация

Since the second half of XX century, the territory of Georgia underwent strong human impact and now is on the verge of environmental crisis. The population increase and widening of economic activity have lead to the catastrophic landscape changes in some regions. The paper deals with concrete data on man-induced changes of land-forms and hazardous geomorphic processes in Georgia. The criteria of geodynamic stability have been worked out on the basis of morphologic and morphometric analysis and monitoring of the Great Caucasus slopes. The lithologic characteristic of relief is based on formational principle: it requires drawing out the main features of spatial distribution of rocks being the genetically homogeneous and having engineering geologically similar characteristics (hardness, stability, hydraulic permeability, soaking etc.). Authors suggest paying equal attention to engineering geologic properties of rocks and to energy of relief as integral indicator of its stability in the analysis of geomorphologically hazardous places of earth surface.
