Abstract This study presents the sedimentological and pollen analysis, and radiocarbon dating of the palaeochannel fill deposits situated on the wide alluvial ridge on which 131 archaeological sites were discovered. The analyzed territory covers the right bank of the San river valley (in the area of the Leszno profile) with an area of 72.5 km2. Increase of fine-grain sand sediments, and the presence of redeposited fragments of clayey silts (soil aggregates) correlates well with the increase man’s activity in the 2nd and the 1st half of the 1 st millennia BC (the decline of the Mierzanowice culture, the Trzciniec culture, the Tarnobrzeg Lusatian culture) as well as in the 1st millennium AD (the Przeworsk culture and the early Medieval settlement) and with transformation of plant communities recorded in the palynological sequence. The layer of sediments at the depth of 85–69 cm with the highest proportion of the finest clay fraction may indicate the reduction of cultivation or abandonment of arable land (the pre-Roman (La Tène) period).

在圣河（Sandomierz 盆地，波兰东南部）的牛轭湖沉积物中记录的史前人类住区的时间变化

摘要 本研究介绍了位于宽阔冲积脊上的古河道填充沉积物的沉积学和花粉分析以及放射性碳测年，在该处发现了 131 个考古遗址。分析的领土包括圣河谷的右岸（在 Leszno 剖面区域），面积为 72.5 平方公里。细粒砂沉积物的增加以及粘土质淤泥（土壤聚集体）的再沉积碎片的存在与公元前 1 千年的第 2 和第 1 半年人类活动的增加（米尔扎诺维采文化的衰退、 Trzciniec 文化、Tarnobrzeg Lusatian 文化）以及公元 1 世纪（Przeworsk 文化和中世纪早期定居点）以及孢粉序列中记录的植物群落转化。
