In the conventional research using carbon isotope, the isotopic ratio in CO2 derived from soil organic matter decomposition (SOMD-CO2) is assumed to be equal to that of soil organic matter (SOM). However, this assumption is questionable. Therefore, to validate this assumption, we carried out a laboratory experiment to measure δ^\u003c13\u003eC value in SOMD-CO2. The measurement results showed that in the surface soil, δ^\u003c13\u003eC value in SOMD-CO2 is equal to that of SOM, but in the depth soil, δ^\u003c13\u003eC value in SOMD-CO2 is larger than that of SOM.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}, {"subitem_description": "土壌から大気中へのCO2フラックスを生成源毎に分けて評価することは、森林内の炭素循環を埋解する上で重要である。炭素同位体利用による従来の解析では、生成源の一つである土壌有機物(SOM)の分解に由来するCO2(SOMD-CO2)の炭射同位体比にはSOMと等しい同位体比が仮定されてきた。そのため本研究では、仮定の妥当性を検証するために、山地森林での土壌中CO2およびSOMの炭素同位体比の観測を行うとともに、室内実験にて土壌有機物分解における同位体比変化の有無を調べた。実験により表層土壌では、SOM とSOMD-CO2のδ^\u003c13\u003eC値の間に有意な差はなかったが、深部土壌ではSOM よりSOMD-CO2のδ^\u003c13\u003eC値が大きいことが確認された。", "subitem_description_language": "ja", "subitem_description_type": "Abstract"}]}, "item_9_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/sumrua.21.145", "subitem_identifier_reg_type": "JaLC"}]}, "item_9_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "名古屋大学年代測定資料研究センター", "subitem_publisher_language": "ja"}]}, "item_9_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "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": "守屋, 耕一", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "83118", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "森泉, 純", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "83119", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "山澤, 弘実", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "83120", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "飯田, 孝夫", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "83121", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Moriya, Koichi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "83122", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Moriizumi, Jun", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "83123", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yamazawa, Hiromi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "83124", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Iida, Takao", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "83125", "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": "2018-02-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "21-22.pdf", "filesize": [{"value": "3.5 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 3500000.0, "url": {"label": "21-22.pdf", "objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/12866/files/21-22.pdf"}, "version_id": "4abd6ce9-5300-4398-b28c-947ea70529a7"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "SOMD", "subitem_subject_scheme": "Other"}, {"subitem_subject": "SOM", "subitem_subject_scheme": "Other"}, {"subitem_subject": "δ^\u003c13\u003eC", "subitem_subject_scheme": "Other"}, {"subitem_subject": "土壌有機物", "subitem_subject_scheme": "Other"}, {"subitem_subject": "土壌有機物分解二酸化炭素", "subitem_subject_scheme": "Other"}, {"subitem_subject": "安定炭素同位体比", "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": "土壌有機物分解二酸化炭素の炭素同位体比", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "土壌有機物分解二酸化炭素の炭素同位体比", "subitem_title_language": "ja"}]}, "item_type_id": "9", "owner": "1", "path": ["1318"], "permalink_uri": "https://doi.org/10.18999/sumrua.21.145", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2011-05-11"}, "publish_date": "2011-05-11", "publish_status": "0", "recid": "12866", "relation": {}, "relation_version_is_last": true, "title": ["土壌有機物分解二酸化炭素の炭素同位体比"], "weko_shared_id": -1}
