However, they were dismantled all at once in the former half of the late Yayoi period, and the group began to live in a decentralized manner on the plateau. This was probably due to the deterioration of the lowland environment by the heavy rainfall which occurred at the end of the middle Yayoi period. It is thought that the growth of the chiefs was delayed because of the dispersion of the group and the disruption of large-scale paddy field management.\nAfter that, at the end of the latter half of the late Yayoi period, the settlements re-entered the lowlands and began to manage vast paddy fields. There was presumably an improvement of the environment due to the convergence of heavy rainfall. During this period, groups from Tokai regions which had been fluidized owing to the previous environmental changes newly immigrated to the lowlands, and by introducing the agricultural “software” cultivated in the lowlands of the Nobi Plain, paddy fields were widely extended in the Tone River lowlands.\nIn the early Kofun period, several double-square burial mounds (zenpo-koho-fun) were built as the tombs of the chiefs. The double square burial mounds in this area originated from the Tokai region, but they are larger in the northwestern Kanto than their prototypes in Tokai. This indicates that the size of the migration was large and that the groups were organized by powerful chiefs. At the end of the Yayoi period, groups from the Hokuriku and Boso areas also moved northward. It is thought that such wide-area social reorganization was caused by drastic changes in land use due to environmental changes and the fluidization of groups, which promoted the formation of a new system in the Kofun period.","subitem_description_type":"Abstract"}]},"item_10002_heading_23":{"attribute_name":"見出し","attribute_value_mlt":[{"subitem_heading_banner_headline":"[共同研究] 戦いと国家形成の環境的基盤 : 炭素14年代と酸素同位体による古気候復原と社会統合過程との比較照合","subitem_heading_language":"ja"},{"subitem_heading_banner_headline":"[Collaborative Research] Environmental Foundation of Wars and State Formation : Reconstruction of Paleoclimate Based on Radiocarbon Dating and Oxygen Isotope Analysis in Combination with Social Integration Process","subitem_heading_language":"en"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立歴史民俗博物館","subitem_publisher_language":"ja"}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"第231集 収録論文 タイトルリスト"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.rekihaku.ac.jp/outline/publication/ronbun/ronbun10/index.html#no231","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00377607","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0286-7400","subitem_source_identifier_type":"PISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"若狭, 徹","creatorNameLang":"ja"},{"creatorName":"ワカサ, トオル","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"WAKASA, Toru","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2023-03-31"}],"displaytype":"detail","filename":"kenkyuhokoku_231_03.pdf","filesize":[{"value":"5.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kenkyuhokoku_231_03.pdf","url":"https://rekihaku.repo.nii.ac.jp/record/2826/files/kenkyuhokoku_231_03.pdf"},"version_id":"80da47ca-5d5c-455a-8918-675f736687c3"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"多雨化","subitem_subject_scheme":"Other"},{"subitem_subject":"集落再編","subitem_subject_scheme":"Other"},{"subitem_subject":"集団移動","subitem_subject_scheme":"Other"},{"subitem_subject":"低湿地開発","subitem_subject_scheme":"Other"},{"subitem_subject":"前方後方墳","subitem_subject_scheme":"Other"},{"subitem_subject":"Increased rainfall","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Reorganization of settlements","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Mass migration","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Lowland development","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Double-square mound","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"[論文] 北西関東における弥生後期の遺跡動態と環境変動","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"[論文] 北西関東における弥生後期の遺跡動態と環境変動","subitem_title_language":"ja"},{"subitem_title":"[Articles] Archaeological Site Dynamics and Environmental Changes in the Late Yayoi Period in the Northwestern Kanto Region","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"3","path":["260"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-31"},"publish_date":"2023-03-31","publish_status":"0","recid":"2826","relation_version_is_last":true,"title":["[論文] 北西関東における弥生後期の遺跡動態と環境変動"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-19T08:15:04.807211+00:00"}
