ABSTRACT- Coastal zone is a zone of contemporary interaction between sea and land, where the specific system of terrestrial and aquatic landscapes is forming. Theory of Paragenetic Landscape Complexes (PGLC) opens new possibilities for studying interconnections between sea and land. According to this theory a paragenetic landscape complex is an integral system of spatial-adjacent terrestrial and aquatic landscapes that are possessed by community of origin and between which an active interchange of matter and energy is realized. Among all PGLC features just the material interchange allows monitoring and evaluating diversity of links between sea and land. Material flows of various kinds, such as solid, liquid, bioorganic and anthropogenic flows that are differed by direction, intensity and other features found basis of matter exchange. Complex study of material flows gives an opportunity to extract coastal zone regions that are characterized by certain type of material interrelation between sea and land. PGLC theory is applied to the studying of the Crimean Black Sea coastal zone. The bases of PGLC distinguishing are coastal dynamic, geology of the coasts, and intensity and direction of costal processes. We have distinguished 7 types of PGLC: (i) Accumulative stable coasts in loose sediments of not ledge coasts; (ii) Accumulative strongly retreated coasts in loose sediments of not ledge coasts; (iii) Erosion very weakly retreated coast in firm sediments of ledge coasts; (iv) Erosion weakly retreated coasts in weak sediments of ledge coasts; (v) Erosion strongly retreated coasts in not ledge coasts; (vi) Erosion-accumulative strongly retreated coasts in not ledge coasts.
