Stream water quality was stable and had little variation, and pH was always near 7.00. Rainfall contained large proportions of both NO^-_3 and SO^2-_4, and the pH was always below 5.40. Stemflow showed a lower pH than that of rainfall. It was suggested that the chemical compositions in both throughfall and stemflow were mainly caused by the wash-off of dry deposition. Soil water has large proportions of both NO^-_3 and Ca^2+, which were caused by nitrification and base cation exchange. Stream water has large proportions of both Na^+ and HCO^-_3 caused by chemical weathering. The time lag from rainfall to discharge peak in a small catchment was much quicker than that of a large one, and it was suggested to control system of discharge in large catchment. A time series of both discharge and δ^18O had the same changes as in the storm runoff. It showed that the increase in discharge was caused by the increase in the direct runoff component in both catchments.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_9_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"農林水産研究情報センターで作成したPDFファイルを使用している。","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_9_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/8713"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18999/bulnuf.15.1","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"名古屋大学農学部付属演習林","subitem_publisher_language":"ja"}]},"item_9_relation_43":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://rms1.agsearch.agropedia.affrc.go.jp/contents/JASI/pdf/academy/56-1683.pdf","subitem_relation_type_select":"URI"}}]},"item_9_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_9_source_id_7":{"attribute_name":"ISSN（print）","attribute_value_mlt":[{"subitem_source_identifier":"0469-4708","subitem_source_identifier_type":"PISSN"}]},"item_9_text_14":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_text_value":"application/pdf"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"一柳, 錦平","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"18970","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"ICHIYANAGI, Kimpei","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"18971","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"加藤, 喜久雄","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"18972","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"KATO, Kikuo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"18973","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":"2018-02-19"}],"displaytype":"detail","filename":"bulnuf_15_1.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"bulnuf_15_1.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/7040/files/bulnuf_15_1.pdf"},"version_id":"ba7116d8-473e-4ab6-8433-af514c355c5f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"森林流域","subitem_subject_scheme":"Other"},{"subitem_subject":"pH","subitem_subject_scheme":"Other"},{"subitem_subject":"水質","subitem_subject_scheme":"Other"},{"subitem_subject":"δ^18O","subitem_subject_scheme":"Other"},{"subitem_subject":"forested catchment","subitem_subject_scheme":"Other"},{"subitem_subject":"pH","subitem_subject_scheme":"Other"},{"subitem_subject":"water quality","subitem_subject_scheme":"Other"},{"subitem_subject":"δ^18O","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":"森林流域における酸素安定同位体組成と主要成分濃度の変化について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"森林流域における酸素安定同位体組成と主要成分濃度の変化について","subitem_title_language":"ja"}]},"item_type_id":"9","owner":"1","path":["872"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-09-03"},"publish_date":"2007-09-03","publish_status":"0","recid":"7040","relation_version_is_last":true,"title":["森林流域における酸素安定同位体組成と主要成分濃度の変化について"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-16T03:52:30.279188+00:00"}
