Klysina N. Lithophilous succession of vegetative communities (groupments) on rocky dumps of the Kryvbas: ecology, typology, dynamics.

The objects are the of lithophilous vegetative communities and its successions of vegetative communities on rocky dumps. The aim is to revealing of features of lithophilous vegetative communities and its successions, formed on rocky dumps of the Kryvbas. Methods - elementary-structural approach, formalizations, standard geobotanical methods, method of the aerial analysis. It was determined that lithophilous vegetative communities are rather scant in variety and possess different taxonomic and petrophytic volume as well as petrophytic indexes. The comparative petrophytic analysis of Ukrainian flower flora and rocky dumps revealed that these particular vegetative communities have mach higher petrophytic indexes then those of other Ukrainian flora. The ecotopic typological schemes of rocky dumps and the developments of vegetative communities were worked out. The mulifactor and sbstate - time cherectesistics with their detailed criteria were taken into consideration. The investigation of lithophilous vefetative communication makes it possible to to take measures for its fastening and . Spheres of use are the foresee the natural growth of rocky dumps, phytorecultivation, training courses.
