Summary

Subject and purpose of work: This article identifies changes in the economic use of the river valley area of the Krzna, which occurred as a consequence of the regulation of its bed from the Klukówka estuary to the estuary of the Krzna to the Bug.

Materials and methods: The analysis was carried out on the basis of cartographic maps and aerial photographs, as well as statistical analyses for the period 1931-2015.

Results: The study confirmed the changes in the economic use of the valley of the Krzna River for the agricultural exploitation of the area and increasing crop yields. The biggest changes encompassed wetlands and swamps, mainly in favour of grasslands, whose area increased by 566%, to 2475.7 ha.

Conclusions: The regulatory work carried out resulted in an increase in arable land, forests and areas for development, as well as in the reduction of water surface area from 251.94 ha in 1931 to 57.28 ha in 2015.

Abstract

The wooden structures unearthed in 2012 during archaeological excavation in the courtyard of the Museum of Archaeology and History in Elbląg have been dated using the dendrochronological method to the period between 1245 and 1302, which allows them to be considered to be parts of a Teutonic fortress. The remains of the wooden building located directly on the prehistoric lacustrine sediments created a unique opportunity to reconstruct the near-shore sedimentation of the Drużno Lake. Geological, malacological and palynological methods were applied during the investigation. The results, compared with the ranges of both the Drużno Lake and the Vistula Lagoon, known from previous studies of the region, allowed the correlation of a phase of a deep lake with the “Roman Period”. Rapid shallowing of the lake occurred in the “Migration Period”. The final disappearance of the lake in the area of modern Elbląg occurred in the early Middle Ages.

Abstract

Subject and purpose of work: The purpose of the study is to present the perspectives of geotourism development in the porphyry quarry Gorce I, which is situated in the Wałbrzyskie mountains. Currently the exploitation of this quarry is suspended. Materials and methods: This work was written after studying the literature on this subject and conducting field research, during which terrestrial laser scanning (TLS) was used, among others. The material gathered during field research was used, among other things, to create a 3D model of the Gorce I quarry. Results: The research and analyses conducted in the porphyry quarry Gorce I allowed for designating a geotourist trail where information boards were placed. Conclusions: The research conducted in the Gorce I quarry confirms the possibility of utilizing this excavation pit for geotourism purposes.

Abstract

The purpose of the work is to characterize the potential for the smart development of urban-rural communes of the Lublin Province as potential catalysts for the implementation of the smart villages’ concept. In order to determine the potential for the smart development, the zero-unitarization method was used. In specific areas of smart village concept a synthetic index was determined. The study negatively verified the relationship between the level of potential for the smart development of the studied communes and the accessibility of transport and communication of the region’s capital. The study also revealed a positive correlation between the size of the urban centre in the urban-rural commune and the level of the potential of smart development of urban-rural communes.
