两城镇的龙山文化城址和环壕

Longshan Cultural City Site and Trench in Liangchengzhen

1998~2001年在日照两城镇遗址的发掘中,经勘探和解剖性发掘,初步确定了内、中、外三圈龙山文化环壕,中圈环壕的内侧发现有夯土城墙。依据发掘所提供的层位关系,尤其是通过环壕内出土的大量典型龙山文化陶器的类型学分析,确认内圈环壕的时代为龙山文化早期,其龙山文化早中期之际废弃后又兴建了中圈城墙和壕沟,大体同时或略晚,修建了外圈最大的环壕,两者共同使用到龙山文化中期之末废弃。从而表明中圈城址和外圈环壕在多数时间内是共存的,形成中圈城址和外圈环壕的双重结构的格局。

During the excavation of Liangchengzhen Site in Rizhao from 1998 to 2001,the inner,middle and external trench of Longshan cultural were recognized by exploration and anatomical excavation,and the inner side of the middle trench was found rammed earth city walls.According to the excavated layer relationship,especially the typological analysis of a large number of typical Longshan cultural pottery found in the trench,I confirmed that the period of the inner trench was the early stage of Longshan culture,and that the middle city wall and trench were built after the abandonment of in the early and middle stages of Longshan culture,and that the largest external trench was constructed at the same time or later.The middle and the external trench were abandoned together at the end of middle stage of Longshan culture.Thus,it shows that the middle city wall and the external trench coexist in most of the period,forming a double structure pattern of the middle city wall and the external trench.
