GULLY MODELING FOR FOREST RECLAMATION PURPOSES
- Land Reclamation, Recultivation, and Land Protection
The aim of this study is the theoretical provement of biological recultivation of disturbed soils in urbanized areas. Methodological basis of research was landscape (geosystem) approach. The need to further development of theoretical foundations is justified not only by large amounts of accumulated actual information, but also by growing areas of disturbed lands that need reclamation. The practical significance lies in the elimination of negative consequences of anthropogenic impact on landscapes, the improvement of the human environment and the involvement of disturbed lands into beneficial use. The component analysis of geosystem “waste storage of industrial wastes” was performed to assess the degree of transformation of the territory as the result of anthropogenic impact. As the result, it was found that according to degree and nature of changes of landscape forming components, the given geosystem can be considered as highly modified (disturbed). In this regard, recultivation should culminate in a biological stage, aimed at the development of geosystem as a whole. As a result, a cultural landscape that will provide the maximum biological efficiency with minimum energy costs and will have the necessary stability, self regeneration potential and great biodiversity must be created in the restored area. This achievement is possible at complex use of different types of land reclamation. The classification of land reclamation used at the biological stage of recultivation is offered. It was found that the use of various types of land reclamation implemented by carrying out reclamation activities, which in turn, are fulfilled by the appropriate methods and techniques, provides the formation of the cultural landscape on the recultivated territory. The stages of artificial phytocenosis creation on disturbed lands in urbanized areas are developed and theoretically proved.
