Paleo-environmental changes in the historical ages and relationship to the population migration of northern people

今年的考察总结包括对鄂霍次克、萨图蒙、阿伊努人文化时期察什族保护村落和状况的特点以及历史时期古环境变化的研究成果。鄂霍次克期察什族保护村落特征和建设情况调查，通过对鄂霍次克和萨图蒙文化遗址的实地考察，对萨图蒙和阿伊努人文化时期进行了考察，了解了它们与鄂霍次克和萨图蒙文化遗址的建造情况的关系，获得了一些关于建造情况的数据，并对作为前两年研究的补充的沿海地区和湖泊的历史时期的古环境变化进行了调查，特别是获得了古环境数据。通过这次调查，…Yayoi、科芬晚期和鄂霍次克文化的暖海侵时期以及15-16世纪的小范围暖期和17-18世纪的小冰期的踪迹明显存在。此外，东北亚研究专家的俄罗斯研究人员提供了有关库页岛和下阿穆尔地区周边情况的资料和文献，了解到近2000年来伴随着冷暖气候波动的古环境变化对北方人民影响很大，因此在弥生文化、库芬晚期和鄂霍次克文化的温暖海侵时期，人们积极迁徙，对这些文化的影响很大，在15-16世纪的小范围暖期和17-18世纪的小冰期，人们迁徙的区域被固定和缩小。在北海道，与本州的联系在当时是最强烈的。这份报告总结了上述调查，并包含了1997-1999年(平成9-11)三年的调查结果。较少

This summary of investigations of this year includes the results of studies, carried out in the coastal regions along the Japan Sea and the inland, on the characteristics of the protective villages and situations of the Chashi during the Okhotsk, Satumon and the Ainu Cultural periods and the paleo-environmental changes in the historical ages.The investigations on characteristics of the protective villages and construction situations of the Chashi during the Okhotsk, Satumon and the Ainu Cultural periods were carried out through field survey of the Remains to understand how they were related to the construction situations of Remains of the Okhotsk and the Satumon Cultures and several data on the construction situations were obtained.The investigations on the paleo-environmental changes in the historical ages were done at the coastal areas and lakes which were suppliments of the previous two years studies, and data on paleo-environments were obtained especially. By this investigation the … More existence of traces of warm transgression periods of the Yayoi, Late Kofun and Okhotsk Cultures as well as small scale warm period of 15-16 th century and Little Ice Age in 17-18 th century were clearly recognized. In addition informations and literatures relating to the situations around the Sakhalin and Lower Amur Areas were obtained by the courtesy of Russian researchers who are specialists of NE Asia studies.Consequently it was understood that the paleo-environmental changes with fluctuations of warm and cold climates during the last 2,000 years influenced greatly to the northern people and as a result people migrated actively during the warm transgression periods of the Yayoi, Late Kofun and Okhotsk Cultures and affected strongly to the these cultures, and the areas of the people migration was fixed and narrowed during the periods of the small scale warm period of 15-16 th century and the Little Ice Age of 17-18 th century. In Hokkaido the connection to Honshu became the strongest at that time.This report summaries the above-cited investigations and contains the results of investigations of three years from 1997-1999 (Heisei 9-11).
