GULLY MODELING FOR FOREST RECLAMATION PURPOSES
- Land Reclamation, Recultivation, and Land Protection
The purpose of the given work is to improve the organization of sustainable land use including agricultural land on the basis of adaptive landscape zoning for the development of soil protection measures complex in the land management plan on the example of a particular catchment area and to determine the ecological and economic efficiency of these activities. The relevance of research is due to the fact that sustainable land use is impossible without a deep consideration of interrelations between ecological and economic factors affecting the quantitative and qualitative land conditions. That is why the adaptive-landscape approach plays a decisive role in planning of agricultural enterprises territory, the essence of which is that the whole territory is thought of as a set of independent territorial complexes with separately functioning regimes – landscape ecosystems. The design was carried out in the Mostovaya ravine catchment area in Ust-Donetsk district of Rostov region. The initial data was information on site location, agroclimatic conditions, soil cover and the degree of its exposure to erosion processes, land structure and acreage, crop yields in the crop rotation located on the territory under consideration. A pre-project assessment of the territory was carried out, during which two groups of indicators were identified: the natural and anthropogenic components of the ecological hazard of land use, the available planning and cartographic materials were studied. The zoning of the ravine catchment area for agricultural use was carried out on the data obtained. Taking into account the obtained information soil protective crop rotation was designed on erosion hazard areas, areas of heavily washed arable land were withdrawn from intensive use and covered with perennial grasses, additional field shelter belts and runoff controlling forest belts were designed, the fields were re-designed by reference to the relief. The estimated economic effect is more than 10.2 million rubles.
Key words: cultivated land, water erosion, land management, planning, ecological and economic efficiency.
