To characterize the dynamics of these major greenhouse gases in central Siberia during the growing season, we measured fluxes from forest soil and assessed the relationships between CH4 and N2O fluxes and forest floor vegetation types, soil temperature, and moisture conditions. At the soil surface, both CH4 uptake and emission (-6.6 to 3.1 μg CH4-C m-2 h-1) were observed, and CH4 fluxes did not differ among vegetation types. CH4 flux was positively correlated with soil moisture, but not with soil temperature. The small CH4 uptake compared with previous reports was due to CH4 production in response to high precipitation. N2O was also emitted and taken up by soil (-0.2 to 0.4 μg N2O-N m-2 h-1), and N2O fluxes did not differ among vegetation types. N2O flux was negatively correlated with soil moisture and not correlated with soil temperature. Our findings suggest that high soil moisture and low availability of mineral nitrogen resulted in N2O uptake due to denitrification. Furthermore, both CH4 and N2O were emitted from a river at the site; these were produced in the basin of the riverbank rather than deep in the soil.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"　一般に、森林土壌はメタン（CH4）を吸収して、一酸化二窒素（N2O）を放出している。今まで観測空白域だった中央シベリアカラマツ林において、CH4およびN2Oフラックスを測定した。CH4フラックスは土壌水分率が低いと吸収、高いと放出を示した。CH4吸収速度は、他の北方林に比べて小さく、降水量が多いときに、CH4が生成しやすくなるためと考えられた。N2Oフラックスについては、土壌水分率が低いと放出、高いと吸収がみられた。N2O吸収については、低い窒素無機化率と高水分率時の脱窒が原因と考えられた。さらに、CH4とN2Oは河川水からも放出されていて、おもに河畔域における生成が原因と考えられた。","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立極地研究所"}]},"item_10001_relation_12":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"110009794532","subitem_relation_type_select":"NAID"}}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1016/j.polar.2014.01.004"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1016/j.polar.2014.01.004","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12240481","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18739652","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata
