We investigated the growth of young C. japonica, the spatial differences and temporal changes of soil moisture and inorganic nitrogen concentrations in soils along the slope and then considered the relationship between the growth of young C. japonica and the differences in moisture and nitrogen of soils in the Fukuroyamasawa experimental watershed. The growth of C. japonica was faster on the valley bottom than on the ridge. Volumetric water content of the surface soil was higher and saturated groundwater occurred more frequently near the valley bottom. The average concentrations of nitrogen in current-year leaves and the inorganic nitrogen in soil water and groundwater were higher at the valley bottom; while there were no significant differences in total nitrogen concentration and soil C ／ N ratio for different positions on the slope. Inorganic nitrogen is generated from organic matter by microorganisms and the soil moisture regime affects microbial activity. The spatial difference in the soil moisture regime along a slope should affect the growth of young C. japonica directly and indirectly by affecting soil the nitrogen mineralization activity of microorganisms.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"53605","nameIdentifierScheme":"WEKO"}],"names":[{"name":"YAMAMOTO, Tetsuhiro"}]},{"nameIdentifiers":[{"nameIdentifier":"53606","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ASANO, Yuko"}]},{"nameIdentifiers":[{"nameIdentifier":"53607","nameIdentifierScheme":"WEKO"}],"names":[{"name":"HOTTA, Norifumi"}]},{"nameIdentifiers":[{"nameIdentifier":"53608","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SUZUKI, Masakazu"}]}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学大学院農学生命科学研究科附属演習林"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162451","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03716007","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"610","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"The Tokyo University Forests"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学大学院農学生命科学研究科森林科学専攻森林理水及び砂防工学研究室"},{"subitem_text_value":"東京大学大学院農学生命科学研究科附属科学の森教育研究センター"},{"subitem_text_value":"Laboratory of Forest Hydrology and Erosion Control Engineering, Department of Forest Science, Graduate School of Agricultural and Life Sciences, The University of Tokyo"},{"subitem_text_value":"The University Forests, Graduate School of Agricultural and Life Sciences, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山本, 哲裕"}],"nameIdentifiers":[{"nameIdentifier":"53601","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"浅野, 友子"}],"nameIdentifiers":[{"nameIdentifier":"53602","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"堀田, 紀文"}],"nameIdentifiers":[{"nameIdentifier":"53603","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鈴木, 雅一"}],"nameIdentifiers":[{"nameIdentifier":"53604","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":"2017-06-09"}],"displaytype":"detail","filename":"ersh122001.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ersh122001.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25257/files/ersh122001.pdf"},"version_id":"00bcd644-5b26-4bb8-a2c7-b04694b2e008"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"幼齢スギ","subitem_subject_scheme":"Other"},{"subitem_subject":"成長","subitem_subject_scheme":"Other"},{"subitem_subject":"地中の水分量の違い","subitem_subject_scheme":"Other"},{"subitem_subject":"土壌中の窒素養分の違い","subitem_subject_scheme":"Other"},{"subitem_subject":"斜面","subitem_subject_scheme":"Other"},{"subitem_subject":"young Cryptomeria japonica","subitem_subject_scheme":"Other"},{"subitem_subject":"difference of moisture in soil","subitem_subject_scheme":"Other"},{"subitem_subject":"difference of nitrogen nutrient in soil","subitem_subject_scheme":"Other"},{"subitem_subject":"slope","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":"斜面に植栽したスギ幼齢木の成長と水分，養分の違いの関係","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"斜面に植栽したスギ幼齢木の成長と水分，養分の違いの関係"}]},"item_type_id":"4","owner":"1","path":["2498","2497"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-07-17"},"publish_date":"2012-07-17","publish_status":"0","recid":"25257","relation_version_is_last":true,"title":["斜面に植栽したスギ幼齢木の成長と水分，養分の違いの関係"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:35.258417+00:00"}
