Krechkivska G. Ecosystems of dumps of Borislav ozocerite deposit: description, biota, recultivation.

The objects are ecosystems of of dumps of Borislav ozocerite deposit. The aim is to describe the of dumps of Borislav ozocerite deposit on chemical indexes, by composition of microbiota, flora and fauna and to set their influence on soil's recultivation. The methods are chemical, microbiological. Dissertation is devoted to the study of ecosystem of the dumps of Borislav ozocerite deposit. In the dissertation the specific variety of vegetable cover which grows on the soil of dumps is studied in detail at first. It is investigated the chemical and microbiological state of soil of ozocerite deposit. It is set that soil of dumps are poor on the mineral and organic substances (biogenic origin). The plant overgrowing of the technogenic soil-substrat of dumps is prevented by the high concentration of salts and organic substances of technogenic origin in him (phenols, oil products, bitumoids). The role of biota is appraised in recultivation of the dumps. It is well-proven that on the dumps of ozocerite deposit two ecosystems are formed, which differ not only after biota and substrat, but also functional role of microorganisms. On old (steam) ones ecosystem is formed enough with more plentiful specific variety of plants and animals, and on new (extractions) ones - with poorer. Application sphere is monitoring of the state of dumps, training courses.
