Cím:Changes of the cultural landscape on Hajdúhát (Hungary)-from agricultural landscape to the monoculture / Márta László, Balogh Szabolcs, Novák Tibor József
Megjegyzések:The structural diversity, and complexity of land use and landscape components was studied in detail based on historic maps and recent remote sensed data in a study area on loess plateau of Hajdúhát, covered by chernozemic soils with 2500 ha extent dominated even traditionally by agricultural land use, first of all by crop production. At the end of the 19th century, at starting prosperity of individual farming in Hungary 79 individual farms could be found on the study area, in 1941 95, in 1962 154. In following period of the socialist restructuration of agriculture, the ongoing industrialization and expansion of intensive farming the earlier network of farms practically declined. In number of farms a strong decrease can be detected: in 1989 44, according the most recent remote satellite images only 38 farms still exists, and only 23 are in use. At the same time, the share of plough lands increased from 1751 ha (70%) at the beginning of the 19th century, to 2250 ha (90%) in recent times. Extent areas of former wetlands and meadows were occupied by plough lands. Until the 50s of the 19th century wetlands covered totally more than 500 ha (20%), actually they cover less than 10 ha (0.4%), extent of the mown meadows decreased to their third. The orchards, represented originally by an area of 0.8 ha, disappeared completely. The decline of the farm network is also detectably in changes of the road density. Int he first period the total length of roads was 93 km within the study area (3.72 2 km?km-), but it decreased to contemporary times to less than 50 km (2 km?km-2). Based on our results the spatial diversity, and complexity of the landscape characterized even earlier by plough lands showed ongoing reduction, and in recent condition could be characterized rather as agricultural monoculture instead of traditional cultural landscape.
