Identification of extent, topographic characteristics and land abandonment process of vineyard terraces in the Tokaj-Hegyalja wine region between 1784 and 2010

摘要

The terracing of vineyards has been a centuries-old traditional land use type in the Tokaj-Hegyalja region (887?km~(2)). However, most of them have since been abandoned and are occupied by dense vegetation. In this study, we mapped the spatial extent of vineyard terraces, based on aerial photos. We classified the terraced fields, considering their topographic characteristics as assessed by topographic factors (slope, exposure and elevation) and the process of abandonment between 1784 and 2010 using historical and contemporary land use maps. Based on the overall map of vineyard abandonment (scale: 1:120,000), the process of the abandonment of terraces can be divided into six consecutive time intervals (1784–1858, 1858–1884, 1884–1940, 1940–1969, 1969–1989 and 1989–2010). Vineyard terraces were found on 590?ha, which were concentrated on hillsides steeper than 17%, on southwestern, southern and southeastern exposures, and lying between 150 and 500?m a.s.l. In the period between 1884 and 1989, 77.8% of the terraces were abandoned, with a particularly intense period of abandonment between 1940 and 1969, which saw a 31.1% decrease in the extent of cultivated terraces.
