【摘要】 本文综合运用土壤微形态、粒度分析、植硅体研究等方法,重建了焦家遗址大汶口文化中晚期城墙与壕沟”兴建-使用-废弃”的完整过程。结果表明,焦家壕沟开挖于河漫滩相粉砂质沉积物上,先民使用开挖壕沟所得的沉积物修筑了第一期城墙。在壕沟使用期间,降水为沟内带来短期流水,土壤侵蚀堆积构成了壕沟内沉积物的主要来源。人类在壕沟附近的活动较为频繁,并利用清淤所得的沉积物修筑第二期城墙。最终,随着壕沟内侧聚落功能变化,先民逐步放松了对壕沟的管理,城墙壕沟先后废弃。在其主要使用阶段,城墙、壕沟客观上发挥着阻挡来水、聚落防御的功能,其社会意义亦不应忽视。更多还原

【Abstract】 Soil micromorphology,particle analysis and phytolith analysis were applied in this article to reconstruct the entire life cycle of the Dawenkou period moat and rammed-earth wall discovered in jiaojia site,Shandong Province.It is revealed that the moat was excavated on silty alluvium and the sediment obtained from moat construction was used to build the rammed earth wall.During the main using stage,seasonal stream occurred in the moat and soil erosion deposit constitute the main source of the infilling.Human activities near the research area were more frequent and the sediment obtained from dredging was used to build the second wall.With the change of the function of settlements inside the enclosure,management of the moat was gradually stopped,the moat.and the rammed-earth wall were both abandoned in the end.In its main use stage,the wall and the moat performed the function of water preventing and settlement defense,and its social significance should not be ignored.更多还原
