杨家圈遗址水田遗迹探查

Exploration of Paddy Field Remains at the Yangjiaquan Site

位于胶东半岛中部的杨家圈遗址,主要遗存属于大汶口文化晚期和龙山文化时期。在1979年的发掘发现稻遗存的基础上,2004年山东大学和九州大学联合对遗址周边地区进行了勘察,在遗址之外的北侧小河北岸发现疑似'稻田'的遗迹。2015~2016年冬,双方继续对遗址北侧的低平地段进行调查,在距今地表2米以下的一定范围内,发现密度较大的水稻植硅体,同时还有芦苇等喜水植物伴出。据此推定杨家圈遗址北侧规模不大的扇形低地,可能是早期水田和河道的交错分布地带。而水田的具体结构和准确时代,有待于今后的田野考古发掘加以解决。

Yangjiaquan site,which mainly consisted of the culture remains of late-Dawenkou and Longshan period,is located in the middle of Jiaodong peninsula.Rice remains was first found in this site in the 1979 excavation.In 2004,the joint investigation team of Shandong university and Kyushu university surveyed the surrounding area of the site,and suspected remains of paddy fields was found on the northern river bank of the site.In 2015-2016,this team investigated the low-lying area in the north of the site.The high-density rice phytolith was found at a depth of 2 meters underground,as well as water-loving plants such as reeds.Therefore,the fan-shaped lowland on the north side of the Yangjiaquan site is presumed to be the intersecting distribution area of early paddy fields and river channels.However,the concrete structure and accurate times of the paddy fields need to be confirmed in the future archaeological excavation.
