Structuring a Database of Remote Sensing Methods and GIS in Reclamation of Disturbed Land

Martin Banov, Svetla Rousseva, Evlogi Markov and Nevena Miteva

The main large consumer of the products of the coal appear thermal power plants (TPP). The activity of similar energy complexes is connected with the recovery of significant quantities of coal, characterized by the different qualities depending on the region from which they are derived. The process of production of electrical energy is accompanied with the accumulation of a large quantity of waste products (mainly ash and breeze), which are disposed in a over burdens.

Besides the release of polluting aerosols in the process of energy production, constructed over burdens additionally polluted components of the environment especially when it is not identifying measures for their restoration.

The purpose of the paper is:

• To develop a technological scheme for closure and reclamation of landfill of TPP "Rousse - West" by locating in GIS disturbed terrain (tailing pond).

• To build the ASR /Geographical database/ that integrates data from different sources, including field measurements, data from the physical and chemical analysis and others.

• To justify the relevance of this approach in landfills, mines and damaged areas of different types, subject to reclamation.

• A propose for humus reclamation with formation of favorable plant growth conditions and improving of reclaimed area properties acceleration has made.

• Two types of biological reclamation, included artificially grassing with selective usage of grass species medley or afforestation with suitable wood species in combination with grass formations have been under consideration.

For grassing are proposed the perennial wheat forage species: Festuca pratensis, Huds., Festuca rubra, L., Poa pratensis, L., Trifolium pratense, L. and Trifolium repens, L. For afforestation are proposed wood species: Robinia pseudoacacia, L. in combination with grass formation, included Lolium perenne, L. and Alopecurus pratensis, L.
