We propose convenient indices of stand density for the management of overcrowded Japanese larch and Japanese red pine plantations. The analysis included the relative spacing index, the ratio of mean height to mean diameter, and stand basal area. Analysis of the degree of crowding and onset of tree mortality revealed that the relative spacing index and the ratio of mean height to mean diameter were the most convenient of the three variables.\nThe maintenance of Japanese larch and Japanese red pine stands with a relative spacing index≤20% effectively prevents self-thinning mortality.","subitem_description_type":"Other"}]},"item_41_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"KUNISAKI, Takashi"}]}]},"item_41_publisher_14":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"岩手大学農学部附属寒冷フィールドサイエンス教育研究センター"}]},"item_41_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0286-4339","subitem_source_identifier_type":"ISSN"}]},"item_41_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"岩手大学環境科学系"}]},"item_41_version_type_27":{"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":"國崎, 貴嗣"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-11-14"}],"displaytype":"detail","filename":"biuf-n45p25-36.pdf","filesize":[{"value":"643.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"biuf-n45p25-36.pdf","url":"https://iwate-u.repo.nii.ac.jp/record/9033/files/biuf-n45p25-36.pdf"},"version_id":"abfd3338-c856-442e-b692-26f031faae2e"}]},"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":"過密なカラマツ，アカマツ人工林における簡便な密度管理指標の探索","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"過密なカラマツ，アカマツ人工林における簡便な密度管理指標の探索"}]},"item_type_id":"41","owner":"3","path":["1506"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-07-31"},"publish_date":"2014-07-31","publish_status":"0","recid":"9033","relation_version_is_last":true,"title":["過密なカラマツ，アカマツ人工林における簡便な密度管理指標の探索"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T11:17:54.951407+00:00"}
