Анализ устойчивости агроландшафтов в лесостепной зоне Красноярского края и мероприятия по их охране

Abstract

The purpose of the study. On the basis of an assessment of the conditions and factors affecting the agro landscapes of an agricultural organization, design a set of protective measures aimed at increasing their sustainability. Research methods. The methodological basis was the systematic approach and its variety in the study of landscapes – landscape analysis. The methodological base should include the works of domestic and foreign scientists aimed at solving the problem of conservation of land resources and their protection. Statistical processing of analytical materials was carried out using dispersion and cluster analyses. The cartographic method and methods of GIS technologies were also used in the analysis of areas and modeling of processes. Research results. An agro-ecological assessment of the territory of agricultural land use, with an area of more than 16 thousand hectares, located in the forest-steppe of the Krasnoyarsk Territory, was made. It has been established that the territory is typical and the results obtained can be used in the analysis of sustainability and the development of measures for the protection of agricultural land uses operating in similar natural and climatic conditions in the Russian Federation and the Republic of Kazakhstan. Landscape areas are defined on the map-scheme, conditions and factors influencing the stability of agrolandscapes are described. It has been established that the main limiting factor influencing the stability of the territory is deflation, which manifests itself differently within landscape areas. A scientifically based complex of protective agro-, phyto-, forest reclamation measures has been developed, corresponding to the allocated land categories in the landscape-agro-ecological zoning scheme, aimed at increasing the efficiency and sustainability of agricultural land use. Conclusion. 1. An assessment of the sustainability of landscape areas (agrolandscapes) of an agricultural organization has been made. 2. Unique schematic map of landscape areas, steepness of slopes, erosion hazard of the territory, landscape-erosion zoning, and studied agricultural land use were compiled, the ecological state of the territory was determined. 3. A complex of agro-, phyto-, forest reclamation measures is presented, differentiated according to landscape areas for deflation-hazardous land categories in the landscape-agro-ecological zoning scheme, aimed at their protection and increasing the sustainability of the agricultural land use area. 4. The results of scientific research can be applied by agricultural producers, research institutions, regional and municipal authorities in the organization, planning, monitoring, evaluation and management of land resources in the Russian Federation and the Republic of Kazakhstan.
