Both the height and the eccentricity of the center of gravity of a tree's foliage were used as indexes of the stability of a crown. The results of simulation were summarized as in the following : 1. The thinning intensity largely effected the stability of crowns. The risings of center of gravity accompanying with the tree-height-growth were reduced in accordance with an increasing in the thinning ratio. This result suggests the possibility of keeping the vertical stability of crowns by the execution of intensive thinning. The relative frequency of occurrence of the trees supplied with changing eccentricity during 5 years after the thinning, increased linearly with the thinning ratio. 2. The upper and the all storied thinning reduced eccentricity more significantly than other thinning systems did. The cutting of the trees which were large enough to suppress the others was deemed to be effective to keep the horizontal stability of crowns. 3. The line thinning showed less effects on the individual foliage weight than other thinning systems did. Consequently, the planning of the thinning ratio by using the stand density control diagram was deemed to be inadaptable to the line thinning system. 4. The line thinning enlarged the eccentricity more than other thinning systems did, showing the tendency to lose the horizontal stability of crowns.","subitem_description_type":"Other"}]},"item_7_full_name_2":{"attribute_name":"著者よみ","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"ミズナガ, ヒロミ"}]}]},"item_7_full_name_3":{"attribute_name":"別言語の著者","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"MIZUNAGA, Hiromi"}]}]},"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":"水永, 博己"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-27"}],"displaytype":"detail","filename":"KJ00000068497.pdf","filesize":[{"value":"694.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00000068497.pdf","url":"https://ir.kagoshima-u.ac.jp/record/3434/files/KJ00000068497.pdf"},"version_id":"b38d3d53-cccd-4b3d-822c-d49a04b1d03f"}]},"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":"間伐が樹冠の安定性に及ぼす影響の予測","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"間伐が樹冠の安定性に及ぼす影響の予測"}]},"item_type_id":"7","owner":"3","path":["44","4962"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-31"},"publish_date":"2015-03-31","publish_status":"0","recid":"3434","relation_version_is_last":true,"title":["間伐が樹冠の安定性に及ぼす影響の予測"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2024-01-30T05:15:58.328284+00:00"}
