For examination of their effects on forest ecosystem, we conducted preliminary survey using a dendroecological technique. Tree-ring samples were collected mainly in the southern part of the Ishikari Lowland where some layers of pyroclastic fall were found. The number of tree-rings was counted and tree-ring widths were measured. As a result, we could distinguish from the 1739 tree ring measurements the effect of eruption with its subsequent Ta-a volcanic deposition. This proves that the effect on tree growth changed in proportion to distance from the origin of the pyroclastic fall.","subitem_description_type":"Abstract"}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Department of Geography, Tokyo Metropolitan University"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00200173","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03868710","subitem_source_identifier_type":"ISSN"}]},"item_3_version_type_16":{"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":"Oka, Shuichi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takaoka, Sadao"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-08-04"}],"displaytype":"detail","filename":"20005-31-013.pdf","filesize":[{"value":"364.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"20005-31-013.pdf","url":"https://tokyo-metro-u.repo.nii.ac.jp/record/2939/files/20005-31-013.pdf"},"version_id":"b697f9e1-f89d-423b-8b26-11eb48b670a2"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"forest ecosystem","subitem_subject_scheme":"Other"},{"subitem_subject":"pyroclastic fall","subitem_subject_scheme":"Other"},{"subitem_subject":"dendroecology","subitem_subject_scheme":"Other"},{"subitem_subject":"southwestern Hokkaido","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"A preliminary study on the effects of pyroclastic fall deposit on the forest ecosystem in southwestern hokkaido, japan","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A preliminary study on the effects of pyroclastic fall deposit on the forest ecosystem in southwestern hokkaido, japan"}]},"item_type_id":"3","owner":"3","path":["554"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-11-30"},"publish_date":"2010-11-30","publish_status":"0","recid":"2939","relation_version_is_last":true,"title":["A preliminary study on the effects of pyroclastic fall deposit on the forest ecosystem in southwestern hokkaido, japan"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T18:24:43.911565+00:00"}
