The article evaluates the land use structure in municipalities of the Warmian-Masurian voivodeship (Poland) in 2002–2012. The dynamics of changes in land use and the correlations between the components of the agricultural environment and land use structure were determined.The trends in land use and agricultural land management were identified, and agricultural and forest ecosystems were evaluated. Clusters of municipalities characterized by similar habitat conditions and land use were identified. The land use structure in the analyzed region was highly stable, and it was strongly correlated with the natural environment. A minor decrease in the percentage share of arableland, grassland and orchards was noted, and it was accompanied by an increase in forest cover in all municipalities. The forest cover in Warmia and Mazury exceeds the level planned for 2020. The applied classification methods produce highly similar results, and they point to clear regional variations in the natural and agricultural environment. The northern part of the region comprisesmostly agricultural land, and it ranks lower with regard to its ecological importance. Agricultural acreage is also the predominant type of land use in the south-western part of the region despite poor quality soils. The southern and south-eastern parts of the region are also characterized by low quality soils, they feature a higher share of forests and grasslands which increase their ecological significanceand raise their recreational appeal
Retaining walls with the use of reinforced soil technology are frequently used in building light retaining constructions, whose facing is made from gabion baskets. Geosynthetics or steel double woven mesh play the role of reinforcement rod in this type of structures. A good alternative for steel woven mesh is welded mesh, which is not prone to the change of mesh geometry during stretching in the main direction. The objective of this dissertation is to find an answer to the question of the steel welded mesh applicability as ground reinforcement in light gabion retaining structures, as well as the comparison of deformations of both meshes types in different ground conditions. The work contains the numerical analysis of meshes stretching, including their assembling in soil using different vulnerability coefficient value. The article has been summarized with conclusions, plans for further experimental research as well as a comparison with previous numerical analyzes.
