The stem analysis was used to estimate sequential height growth. The biomass above the ground was estimated by dimension analysis. The tree height differed corresponding to changes in geographical features. Trees grown on concave slope were about 10m higher than ones on convex slope. The rate of annual height growth on convex slope was about 20cm・yr-1. The height growth on concave slope or steep slope reached a peak at 10- to 20-year-old and decreased gradually until 40- to 50-year-old. The rate of annual height growth after 40- to 50-year-old was about 20cm・yr-1 on concave slope and about 10cm・yr-1 on steep slope. The total biomass above the ground estimated was 214t・ha-1, i.e., 171 in stem, 29 in branch, and 14t・ha-1 in leaf. In comparison with younger stands, the branch biomass was larger, but the leaf one was not different apparently.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"55163","nameIdentifierScheme":"WEKO"}],"names":[{"name":"TANGE, Takeshi"}]},{"nameIdentifiers":[{"nameIdentifier":"55164","nameIdentifierScheme":"WEKO"}],"names":[{"name":"MURAKAWA, Isao"}]}]},"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":"東京大学農学部附属演習林千葉演習林"},{"subitem_text_value":"University Forest in Chiba, Faculty of Agriculture, University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"丹下, 健"}],"nameIdentifiers":[{"nameIdentifier":"55161","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"村川, 功雄"}],"nameIdentifiers":[{"nameIdentifier":"55162","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":"esrh082003.pdf","filesize":[{"value":"565.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh082003.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25517/files/esrh082003.pdf"},"version_id":"c9181a48-808e-4fdc-ae98-e8cd4bb9ff9a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ヒノキ","subitem_subject_scheme":"Other"},{"subitem_subject":"樹高生長","subitem_subject_scheme":"Other"},{"subitem_subject":"地上部現存量","subitem_subject_scheme":"Other"},{"subitem_subject":"Chamaecyparis obtusa","subitem_subject_scheme":"Other"},{"subitem_subject":"Height growth","subitem_subject_scheme":"Other"},{"subitem_subject":"Biomass above the ground","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":"87年生ヒノキ人工林の生長と現存量","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"87年生ヒノキ人工林の生長と現存量"}]},"item_type_id":"4","owner":"1","path":["2578","2577"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-09-03"},"publish_date":"2014-09-03","publish_status":"0","recid":"25517","relation_version_is_last":true,"title":["87年生ヒノキ人工林の生長と現存量"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:43.767958+00:00"}
