Sedimentological analysis of the boring-core data and diatom analysis were done for the southern area of the lowland which was inundated by the Holocene transgression. The stratigraphy of uppermost deposits suggests that the environment of this region has changed from broad marsh with several ponds to unstable land which damaged by frequent floods. The results of diatom analysis support this sedimentary condition. The fluvial effect in the Yahagi River Lowland had become significant since ca. 2,000 yr. B.P., and natural levees had developed after ca. 1,200-1,400 yr. B.P. It has been reported by the previous study that the similar environmental change was seen in the northern half of this lowland. The causes of such environmental and geomorphological changes are considered to be due to the climatic change and deforestation by human activity in the upper reaches.","subitem_description_type":"Abstract"}]},"item_10002_heading_23":{"attribute_name":"見出し","attribute_value_mlt":[{"subitem_heading_banner_headline":"[歴博国際シンポジウム] 過去1万年間の陸域環境の変遷と自然災害史―","subitem_heading_language":"ja"},{"subitem_heading_banner_headline":"[REKIHAKU International Symposium] Terrestrial Environmental Changes and Natural Disasters during the Last 10,000 Years","subitem_heading_language":"en"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15024/00000905","subitem_identifier_reg_type":"JaLC"}]},"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81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/ronbun4/index.html#no81","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":"川瀬, 久美子","creatorNameLang":"ja"},{"creatorName":"カワセ, クミコ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"2543","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kawase, Kumiko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"2544","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-04-01"}],"displaytype":"detail","filename":"kenkyuhokoku_081_24.pdf","filesize":[{"value":"479.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kenkyuhokoku_081_24.pdf","url":"https://rekihaku.repo.nii.ac.jp/record/922/files/kenkyuhokoku_081_24.pdf"},"version_id":"38580deb-7924-4170-ade2-91fc6fba4d1d"}]},"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":"矢作川下流低地における完新世後半の古環境変化（日本列島と周辺域における環境変遷）","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"矢作川下流低地における完新世後半の古環境変化（日本列島と周辺域における環境変遷）","subitem_title_language":"ja"},{"subitem_title":"Late Holocene Palaeoenvironmental Changes in the Yahagi River Lowland, Central Japan（Environment and Human Activities in the Island Arc）","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"3","path":["110"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2016-04-01"},"publish_date":"2016-04-01","publish_status":"0","recid":"922","relation_version_is_last":true,"title":["矢作川下流低地における完新世後半の古環境変化（日本列島と周辺域における環境変遷）"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-08-28T05:17:11.222757+00:00"}
