Studies on the Land-Use History of Kétsoprony Village in the 19th-20th Century with Focus on the Changes of the Biotope Network
332-340Views:94The biotope network has an important role in the case of intensive agricultural landscapes. Our aim was to examine the history of land-use of an intensively managed area – as Kétsoprony village – in the Alföld (Great Hungarian Plain) region and to study the changes in the biotope network, especially the tree rows in time. The biotope network and mainly the tree rows may be importance from the aspect of nature conservation because land use has been dominated by arable lands in the research area for centuries. We have identified the main stages of structural changes by studying historical maps and considering quantitative and qualitative features. We have found that the rate of arable lands was continuously growing while the length of tree rows was decreasing in the 19-20th centuries.

The Examination of the Cultivation-Resulted Effects on the Soils of Turkey Oak Forests and Sessile-Oak Forests
241-246Views:67While examining soil patterns from low ridges and shallow furrows of untouched forest areas we discovered some traces of antropogenic effects. We found that samples from the ridges are argillaceous, succinct, highly-bound and significantly eroded Luvisol samples with a thin layer of humus and strong acidity. By contrast, the samples of the furrows have thin layers of mould and weak acidity. HTM (a pebble, which came from other areas) and other artificial products can be found in both geological sections and they refer to the antropogenic effects and the accumulations and eroding processes resulting from ci-devant, 15-20 cm deep ploughing. Our findings give an evident proof of former cultivations and their soil status-changes in the currently forest-covered areas.
