On the other hand, a great deal of research has been done regarding growth of coniferous plantations. However, pure even-aged stands, especially stands older than 15 to 20 years after the first canopy closure, have been the main subject of the research on the growth of coniferous plantations. Moreover, light control as well as stand density control are necessary to establish two-storied stands, and an indicator of light conditions for understory trees on the basis of the condition of overstory trees is needed. However, the data available on two-storied plantations is far less than that on pure even-aged stands.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"54720","nameIdentifierScheme":"WEKO"}],"names":[{"name":"TATSUHARA, Satoshi"}]}]},"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":"東京大学農学部林学科"},{"subitem_text_value":"Department of Forest Science, Faculty of Agriculture, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"龍原, 哲"}],"nameIdentifiers":[{"nameIdentifier":"54719","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":"esrh094005.pdf","filesize":[{"value":"4.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh094005.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25438/files/esrh094005.pdf"},"version_id":"7d1bced2-8320-4ba1-b449-e793e99e8b11"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"材積成長モデル","subitem_subject_scheme":"Other"},{"subitem_subject":"二段林","subitem_subject_scheme":"Other"},{"subitem_subject":"生産力","subitem_subject_scheme":"Other"},{"subitem_subject":"閉鎖度","subitem_subject_scheme":"Other"},{"subitem_subject":"成長予測","subitem_subject_scheme":"Other"},{"subitem_subject":"Volume growth model","subitem_subject_scheme":"Other"},{"subitem_subject":"Two-storied stand","subitem_subject_scheme":"Other"},{"subitem_subject":"Productivity","subitem_subject_scheme":"Other"},{"subitem_subject":"Crown density","subitem_subject_scheme":"Other"},{"subitem_subject":"Growth prediction","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":"人工複層林の成長に関する理論的研究 : スギ二段林の成長モデル","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"人工複層林の成長に関する理論的研究 : スギ二段林の成長モデル"}]},"item_type_id":"4","owner":"1","path":["2554","2553"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-09-03"},"publish_date":"2014-09-03","publish_status":"0","recid":"25438","relation_version_is_last":true,"title":["人工複層林の成長に関する理論的研究 : スギ二段林の成長モデル"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:41.676818+00:00"}
