There are two components that generate CO2 in soil, soil organic matter decomposition and root respiration. Although the former is relatively well understood, the root-derived CO2 efflux has not been evaluated sufficiently. The objective of our research is to estimate depth profile of the root respiration rate. Thus we developed a box model which calculates the depth profile. In this paper, we discussed about the adequacy of calculated result by comparing it to the observed soil respired CO2 flux with trenching method. The result showed that the depth profile of root respiration rate decreased with soil depth. This is attributed to the distribution of fine roots which dominate root respiration. And the estimation result of root respiration was almost equal to observed one.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}, {"subitem_description": "土壌呼吸CO2の放出は全球的な炭素循環と環境中の^\u003c14\u003eC移行において、加えて、大気中CO2の増加 による全球的な気候変動を予測するためにも、非常に重要な要素である。土壌中にはC02を生成する2 つの要素、土壌有機物分解と根呼吸が存在する｡前者は比較的良く理解されつつある一方、根に由来す るCO2放出は十分な評価がなされていない。本研究の目的は、根呼吸速度の深さ分布を評価することで ある。ボックスモデルを開発し、計算結果の正確性をトレンチ法による土壌呼吸CO2フラックス観測値 と比較した｡計算結果は、深いほど小さい根呼吸速度分布を示した。これは根呼吸を支配する細根の分布による。根呼吸によるCO2フラックスの計算結果は観測結果とほぼ一致した｡", "subitem_description_language": "ja", "subitem_description_type": "Abstract"}]}, "item_9_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "第22回名古屋大学年代測定総合研究センターシンポジウム平成21(2009)年度報告", "subitem_description_language": "ja", "subitem_description_type": "Other"}]}, "item_9_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/sumrua.21.61", "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": "蜂谷, 真史", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "83020", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "森泉, 純", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "83021", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "山澤, 弘実", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "83022", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "HACHIYA, Masashi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "83023", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "MORIIZUMI, Jun", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "83024", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "YAMAZAWA, Hiromi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "83025", "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": "21-9.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": "21-9.pdf", "objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/12853/files/21-9.pdf"}, "version_id": "994aa9ec-bc19-4871-a05e-2a2bc201d750"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "root respiration", "subitem_subject_scheme": "Other"}, {"subitem_subject": "soil respiration", "subitem_subject_scheme": "Other"}, {"subitem_subject": "carbon cycle", "subitem_subject_scheme": "Other"}, {"subitem_subject": "carbon isotope", "subitem_subject_scheme": "Other"}, {"subitem_subject": "global climate change", "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": "炭素同位体比を用いた森林土壌呼吸中の根呼吸の評価", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "炭素同位体比を用いた森林土壌呼吸中の根呼吸の評価", "subitem_title_language": "ja"}]}, "item_type_id": "9", "owner": "1", "path": ["1318"], "permalink_uri": "https://doi.org/10.18999/sumrua.21.61", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2011-05-10"}, "publish_date": "2011-05-10", "publish_status": "0", "recid": "12853", "relation": {}, "relation_version_is_last": true, "title": ["炭素同位体比を用いた森林土壌呼吸中の根呼吸の評価"], "weko_shared_id": -1}
