Features of the formation of a landscape‐ecological framework: A case study of key districts in the Orenburg region, Russia

Abstract
Aim. To identify regional peculiarities of the formation and functioning of the landscape‐ecological framework (LEF) of a territory using the example of districts in Orenburg Oblast.
The study is based on an integrated framework‐landscape approach that combines traditional methods of geographical analysis with modern geoinformation technologies. The informational foundation of the work consisted of official statistical data, remote sensing data and materials from field studies.
The key components of the LEF districts in the Orenburg region have been identified. Significant differences in the structure and functioning of the LEF in the studied districts were identified. Svetlinsky District is characterized by a higher degree of connectivity of LEF elements, while Pervomaysky District has the lowest. The role of hunting grounds as buffer elements and ecological corridors was determined; prospects for the formation of recreational and environmental landscape complexes within the LEF structure to reduce anthropogenic pressure on core areas were identified.
Significant differences in the structure and functioning of the LEF in the studied districts were identified. Svetlinsky district is characterised by a higher degree of connectivity of LEF elements, while Pervomaysky district has the lowest. Analysis of remote sensing data in all districts revealed significant discrepancies between official land category data and actual land use. The role of hunting grounds as buffer elements and ecological corridors was determined and prospects for the formation of recreational and environmental landscape complexes within the LEF structure to reduce anthropogenic pressure on core areas were identified.
