The regional study on water transports at internal water revel and on the site in early Japan

本研究的目的是利用鄂西古平原的内部水位遗址和历史影像环境对鄂西古平原进行区域历史佐证。特别是，我们应该在对手稿、古地图和考古遗迹分析的基础上，以新的认识推进对NUTARI-palisade的发现，而不是枯燥的调查和挖掘。(1)根据新潟市Nuttari部分的Jokyo地图，推测了nutari栅栏的位置，并进行了钻孔调查。我们证实了大约5000年前在铁轨下方约18米深处的火山灰流和沼泽的积累，并确认有必要从根本上改写迄今为止根据陆地表面观察得出的结论，即新沙丘III的形成被认为是在古墓时代形成的，实际上是在绳纹时代中期之前。在大约5米深的地方，我们发现了一个古老的地层……更多的表土上面堆积着植被的遗迹，碳14的数据约为1180±30年。我们使用了地震探测中常用的地质切片机来进行检查，而不是挖掘。我们能够确定这个地区是古老的湿稻田。我们认为在这片土地上还保留着努塔里栅栏和坎巴拉港的遗址。(3)地质特征方面，进一步认识了越后平原的砂障体系和三角洲的形成以及构造作用。我们对NUTARI和IWAFUNE栅栏之间的内部水位产生的密切联系有了新的认识。对于中世纪时期，我们已经确定了gejyo -船在Age河和Shinano河上的自主管理活动，我们已经了解了该地区区域特征的自然发展，我们已经实施了补充调查。(4)与韩国、美国、英国的教授在国际/地区跨学科学术研讨会上进行交流，并一致呼吁与世界各地的学者分享我们的研究成果，以促进区域和比较研究。我们还举行了一个面向普通观众的公开研讨会。少

The purpose of this study has been to make the regional history evidence with the sites of internal water level and with the environment of historical images on ECHIGO-Plain. Specially, we should advance to discovering of NUTARI-palisade with a new understanding based on analysis of manuscripts, old maps and archeological remains, and with a boring survey & excavation.(1)The conjectured location of the NUTARI-palisade has been OSE that is based on Jokyo map of the Nuttari section of Niigata City, and we conducted a boring survey. We verified an accumulation of a flow of volcanic ash and a swamp from about 5000 years ago at a depth of about 18 meters beneath the railroad tracks and confirmed the need to fundamentally re-write the conclusion heretofore, derived from land surface observations, that formation of the new sand dune III presumed to have been formed in the Tomb Age, actually dates from before the middle Jomon era.(2)At a depth of about five meters we discovered an old stratum … More of topsoil above which were accumulated remains of vegetation with a carbon 14 data of about 1180 plus-or-minus 30 years. We employed a geoslicer commonly used in probing earthquakes to examine in stead of excavation. We were able to determine that this area was old wet rice paddy. And we have thought that there is remained in this soil of the sites of NUTARI-palisade and KANBARA-harbor.(3)As for geological features, we advanced general understanding of the action of sand barrier systems and delta creation that formed the Echigo Plain and also geotechtonic structures.We have advanced a new understanding the intimate link created by the internal water level between the NUTARI and IWAFUNE palings. For the medieval era, we have identified the autonomous management of the activity of the GEJYO-boats that plied both the Age and Shinano rivers, we have understood natural development of the regional characteristics of the area, and we have implemented supplementary investigations.(4)These research results were presented at an international/regional interdisciplinary symposium in an exchange with Professor of Korea, USA, UK, these scholars uniformly called for sharing of our studies with scholars throughout the world for the purpose of promoting regional and comparative study. And we held a public symposium directed at general audience. Less
