DON) and some deciduous broad-leaved species was investigated by annual ring chronologies. About 60 years ago, all sample trees of hiba and sugi showed synchronous increases in radial growths, and many of the broad-leaved trees were established. In addition to this, many trees also showed increases in growth about 160,130,90 and 35 years ago. According to these results, it became clear that some disturbances had produced canopy openings in the stand at these times. The disturbance which occurred 60 years ago is presumed to have been an intensive cutting of broad-leaved trees for charcoal making. This stand is regarded to have been formed under the influence of the intensive disturbance affecting a vast area which produced the synchronous rapid growth of advanced saplings of hiba in the undergrowth.","subitem_description_type":"Other"}]},"item_16_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"72360","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SUGITA, Hisashi"}]}]},"item_16_publisher_14":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本森林学会"}]},"item_16_relation_16":{"attribute_name":"異版である","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110002830480","subitem_relation_type_select":"URI"}}]},"item_16_rights_18":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本森林学会"},{"subitem_rights":"本文データは学協会の許諾に基づきCiNiiから複製したものである"}]},"item_16_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0021-485X","subitem_source_identifier_type":"ISSN"}]},"item_16_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"岩手大学農学部附属演習林, （現）独立行政法人森林総合研究所"}]},"item_16_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":"杉田, 久志"}],"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":"jjfs-v75n2p100-107.pdf","filesize":[{"value":"623.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"jjfs-v75n2p100-107.pdf","url":"https://iwate-u.repo.nii.ac.jp/record/9229/files/jjfs-v75n2p100-107.pdf"},"version_id":"258339ee-347e-4d87-8dc2-8202a4d16d44"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ヒバ林の成立過程(I) : 撹乱の歴史","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ヒバ林の成立過程(I) : 撹乱の歴史"}]},"item_type_id":"16","owner":"3","path":["1510"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-11-05"},"publish_date":"2010-11-05","publish_status":"0","recid":"9229","relation_version_is_last":true,"title":["ヒバ林の成立過程(I) : 撹乱の歴史"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T11:10:02.898017+00:00"}
