Archaeopedological analysis of colluvial deposits in favourable and unfavourable areas: reconstruction of land use dynamics in SW Germany

Colluvial deposits, as the correlate sediments of human induced soil erosion, depict an excellent archive of land use and landscape history as representatives of human-environment interactions. This study establishes a chronostratigraphy of colluvial deposits and reconstructs past land use dynamics in the Swabian Jura, the Baar and the Black Forest in SW Germany. In the agriculturally favourable Baar area multiple main phases of colluvial deposition, and thus intensified land use, can be identified from the Neolithic to the Modern Times. In the unfavourable Swabian Jura increased colluvial deposition began later compared to the more favourable areas in the Baar. The same holds true for the unfavourable areas of the Black Forest, but intensified land use can only be reconstructed for the Middle Ages and Early Modern times instead of for the Bronze and Iron Age as in the Swabian Jura. Land use intensity and settlement dynamics represented by thick, multi-layered colluvial deposits increas...坡积物作为人为诱发土壤侵蚀的伴生沉积物，是记录土地利用与景观历史的优质沉积档案，亦是人地相互作用的典型代表。本研究针对德国西南部施瓦本侏罗山、巴尔地区与黑森林的坡积物建立了年代地层序列，并重建了该区域既往的土地利用动态变化。在农业条件优越的巴尔地区，可识别出自新石器时代至近现代的多期主要坡积沉积事件，对应土地利用强度的显著增强。而农业条件较差的施瓦本侏罗山，其坡积沉积增强的起始时间晚于巴尔地区。黑森林的条件较差区域也呈现相同规律，但其土地利用强度增强仅可追溯至中世纪与近代早期，而非施瓦本侏罗山的青铜时代与铁器时代。以厚层多层坡积物为代表的土地利用强度与聚落动态正呈现增强态势……
