The δ\u003c^13\u003eC values of soil respired CO_2,which were obtained by the isotopic mass balance using the chamber method, showed seasonal fluctuations ranging from -31.0 to -24.5‰ with low values from summer to autumn and high ones from winter to spring. Seasonal variation in soil air CO_2 showed high concentraiton and low δ\u003c^13\u003eC value in summer, and low concentration and high δ\u003c^13\u003eC value in winter. They ranged from 0.1 to 3.4% (0.8-3.0% in vertically) in concentration and from -23.7 to -18.1‰ (0.3-4.6‰ in vertically) in δ\u003c^13\u003eC. CO_2 concentration in soil air increased gradually with depth, whereas the δ\u003c^13\u003eC value decreased suddenly at the depth from 10 to 20cm and remained relatively constant below 20cm. The seasonal δ\u003c^13\u003eC fluctuation of soil respired CO_2 was influenced by CO_2 production at a shallow depth in soil (\u003c10cm). On the other hand, the vertical δ\u003c^13\u003eC profiles in soil organic matter increased ca. 2‰ from 10 to 60cm in depth. This δ\u003c^13\u003eCenrichment is much larger than the expected value from the isotopic fractionation during decomposition.", "subitem_description_type": "Abstract"}]}, "item_9_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "タンデトロン加速器質量分析計業績報告 Summaries of Researches Using AMS 2000 (平成12)年度", "subitem_description_type": "Other"}]}, "item_9_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/sumrua.12.147", "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 天然放射性元素測定小委員会"}]}, "item_9_relation_43": {"attribute_name": "異版である", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://ci.nii.ac.jp/naid/110000475686/", "subitem_relation_type_select": "URI"}}]}, "item_9_rights_12": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "名古屋大学年代測定資料研究センター 天然放射性元素測定小委員会"}, {"subitem_rights": "本文データは学協会の許諾に基づきCiNiiから複製したものである"}]}, "item_9_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_9_text_14": {"attribute_name": "フォーマット", "attribute_value_mlt": [{"subitem_text_value": "application/pdf"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Takahashi, Hiroshi Aoki"}], "nameIdentifiers": [{"nameIdentifier": "81173", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Konohira, Eiichi"}], "nameIdentifiers": [{"nameIdentifier": "81174", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Hiyama, Tetsuya"}], "nameIdentifiers": [{"nameIdentifier": "81175", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nakamura, Toshio"}], "nameIdentifiers": [{"nameIdentifier": "81176", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yoshida, Naohiro"}], "nameIdentifiers": [{"nameIdentifier": "81177", "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": "KJ00000187403.pdf", "filesize": [{"value": "838.4 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 838400.0, "url": {"label": "KJ00000187403.pdf", "url": "https://nagoya.repo.nii.ac.jp/record/11653/files/KJ00000187403.pdf"}, "version_id": "8a20f9d3-2429-487e-b294-45a5d2cae296"}]}, "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": "Seasonal variations of concentration and δ\u003c13\u003e^C in soil air CO_2 and soil respired CO_2", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Seasonal variations of concentration and δ\u003c13\u003e^C in soil air CO_2 and soil respired CO_2"}]}, "item_type_id": "9", "owner": "1", "path": ["1237"], "permalink_uri": "https://doi.org/10.18999/sumrua.12.147", "pubdate": {"attribute_name": "公開日", "attribute_value": "2010-05-31"}, "publish_date": "2010-05-31", "publish_status": "0", "recid": "11653", "relation": {}, "relation_version_is_last": true, "title": ["Seasonal variations of concentration and δ\u003c13\u003e^C in soil air CO_2 and soil respired CO_2"], "weko_shared_id": null}
