Here wooden artifacts of Cryptomeria japonica dominate since the Early Jomon Period, when 27% of wooden artifacts were made of its wood in spite of the secondary presence in the surrounding forests. C. japonica established lowland forests at 4,500-2,800 yr.B.P. and 2,000-1,500 yr.B.P. At these periods C. japonica accounted for over 85% of wooden artifacts ranging from boards, spadesor hoes, to dug-outs. Intensive use of C. japonica decreased in the Kofun and Nara-Heian Periods corresponding with the decline of its lowland forests in this area and with the growing preference for Chamaecyparis obtusa in the Kinki District.","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":"10.15024/00000907","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":"植田, 弥生","creatorNameLang":"ja"},{"creatorName":"ウエダ, ヤヨイ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"2551","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ueda, Yayoi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"2552","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_26.pdf","filesize":[{"value":"728.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kenkyuhokoku_081_26.pdf","url":"https://rekihaku.repo.nii.ac.jp/record/924/files/kenkyuhokoku_081_26.pdf"},"version_id":"76718897-4ee1-476e-93a8-2679e912340f"}]},"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":"若狭湾沿岸低地の完新世木材化石群（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":"若狭湾沿岸低地の完新世木材化石群（日本列島と周辺域における環境変遷）","subitem_title_language":"ja"},{"subitem_title":"Holocene Fossil Wood Assemblages and Wooden Artifacts in the Lowland along the Wakasa Bay（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":"924","relation_version_is_last":true,"title":["若狭湾沿岸低地の完新世木材化石群（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":"2023-08-28T05:21:16.795201+00:00"}
