Abstract

THE PROCESS OF NATURAL RESTAURATION ON THE FLORA OF THE STERILE DUMPS SURFACE AND THE ECOLOGICAL RECONSTRUCTION OF THE FRESH DEPOSITED STERIL DUMPS IN THE QUARRY ”LAFARGE CIMENT” (MOLDOVA) S.A. REZINA DISTRICT 

In the present paper dependence of the flora of the natural restoration on the sterile dumps surface has been deter-mined according to the consecutiveness, the age of the heaps (25, 20, 10, 5 years) reported the number of species (63, 52, 28, 25 units). The number of species and their degree of development, their abundance is determined by the period of vegetation carpet formation (years) and the place on the dumps surface (margin of the dump, flat land or the down part of the dump). Such a distribution depends on the soil layer formation process. The soil layer is well formed on the flat land surfaces of the dumps. Based on the results the method for the ecological reconstruction of recently deposited sterile dumps deposited by the forest recultivation method is proposed. The inventory of samplings in the autumn of 2017 showed that the percentage of adapted plants is 85%.
