The crown-form is expressed by parabolic shape. y=α・x^<0.5> wherey : radius of crown (m) x : distance from crown-top (m) α : expanding coefficient of crown-radius The increment of crown-volume is expressed by the following equation (Fig.1). ΔCV=π/2・Cl_2・ Cr_2^2+π/3・(k_2-k_1)・(Cr_2^2+Cr_2・Cr_1+Cr_1^2)-π/2・Cl_1・Cr_1^2 where ΔCV : increment of crown-volume (m^3) Cl : crown-length (m) Cr : radius of crown (m) k : height to living branch (m) ^* subscripts 1 and 2 denote the measurement points, respectively. The growth of stem-volume is calculated by using the stem-volume equation with dbh and tree height data, in two measurement points. The linear relation between growth of stem-volume and increment of crown-volume in Cryptomeria japonica-stand is recognized on each crown-length class. Investigation of the relationship between growth of stem-volume and increment of crown-volume has brought us such an equation as in the following : ΔV=-0.0241+0.0020・ΔCV+0.0087・Cl coefficient of determination R^2=0.80 standard error Se=0.009 (m^3) where ΔV : grouth of stem-volume (m^3) ΔCV : increment of crown-volume (m^3) Cl : crown-length (m) It is expected that growth of stem-volume is in right proportion to increment of crown-volume and to crown-length, respectively. Based on the above mentioned items, it is hoped that we shall be able to describe the growth of individual tree in evenaged Sugi-stand.","subitem_description_type":"Other"}]},"item_7_full_name_2":{"attribute_name":"著者よみ","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"ヨシダ, シゲジロウ"}]}]},"item_7_full_name_3":{"attribute_name":"別言語の著者","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"YOSHIDA, Shigejiro"}]}]},"item_7_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学"}]},"item_7_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"04530845","subitem_source_identifier_type":"ISSN"}]},"item_7_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00040603","subitem_source_identifier_type":"NCID"}]},"item_7_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"610","subitem_subject_scheme":"NDC"}]},"item_7_subject_20":{"attribute_name":"NIIsubject","attribute_value_mlt":[{"subitem_subject":"農学","subitem_subject_scheme":"Other"}]},"item_7_text_24":{"attribute_name":"公開者よみ","attribute_value_mlt":[{"subitem_text_value":"カゴシマ ダイガク"}]},"item_7_text_25":{"attribute_name":"公開者別名","attribute_value_mlt":[{"subitem_text_value":"Kagoshima University"}]},"item_7_version_type_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"吉田, 茂二郎"}],"nameIdentifiers":[{"nameIdentifier":"92274","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":"2016-10-28"}],"displaytype":"detail","filename":"KJ00000068343.pdf","filesize":[{"value":"294.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00000068343.pdf","url":"https://ir.kagoshima-u.ac.jp/record/6464/files/KJ00000068343.pdf"},"version_id":"cb659462-5617-483e-86ab-8828b4e3fbba"}]},"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":"スギの樹冠の変化量と幹材積成長量の関係","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"スギの樹冠の変化量と幹材積成長量の関係"}]},"item_type_id":"7","owner":"3","path":["44","4954"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-06-04"},"publish_date":"2015-06-04","publish_status":"0","recid":"6464","relation_version_is_last":true,"title":["スギの樹冠の変化量と幹材積成長量の関係"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2024-01-30T05:17:36.616600+00:00"}
