河南洛阳王圪垱遗址浮选结果及分析

Analysis of Flotation Results from the Wanggedang Site in Luoyang

王圪垱遗址是一处位于河南伊洛盆地中西部的大型环壕聚落遗址,该遗址主体为龙山中晚期到二里头早期。本次对王圪垱遗址开展的浮选工作,获得了丰富的龙山晚期炭化植物遗存,包括粟、黍、大豆、稻米、小麦五种农作物,以及其他非农作物植物遗存,包括20余种杂草类植物遗存及少量果核类植物遗存。浮选结果显示,粟的绝对数量和出土概率最高,黍和稻米也是重要的农作物资源,该遗址龙山时代晚期存在着稻旱混合的农业经济模式,又以旱作农业为主。王圪垱遗址龙山晚期出土植物遗存研究也为二里头遗址的稻旱混作农业提供了可能的来源,为进一步了解这一都邑性聚落的农业生产特点提供帮助。

The Wanggedang site is a large-scale settlement with moat around,located at the central-western Yiluo Basin,and the dominant remains originated during the middle-late Longshan period to the early Erlitou period.The flotation work carried out gained abundant charred plant remains from the Longshan period,including five crops,i.e.foxtail millet(Setaria italica),broomcore millet(Panicum miliaceum),soybean(Glycine max),rice(Oryza sativa),wheat(Triticum aestivum),and other non-crop plant remains,including more than 20 weeds and a few hard cores.The results indicate that both the absolute number and the ubiquity of foxtail millet were the highest among the five crops,while broomcore millet and rice were the important crop resources.The subsistence pattern of the site during the Longshan period was featured by agricultural economic model of the mixture of wet-dry farming with dry farming being its priority.The plant remains found at the Wangedang site offers the possible source for exploring the wet-dry farming of the Erlitou site,and some crucial data for further understanding the farming characteristics of the state-level settlement.
