A negative correlation was found between the stem density of hardwood colonized and the site index as an indicator of forest site productivity. The effect of the site index on the colonization of hardwood is greater than that of the measures of current light intensity.\nThe stem density of tall hardwood species with seed dispersal type by birds was positively correlated with the number of surrounding hardwood forests. In addition, the mean heights of all life-forms were positively correlated with the number of surrounding hardwood forests. In conclusion, as forest site productivity decreases and the number of surrounding hardwood forests increases, many hardwoods appear to colonize Cryptomeria japonica plantations.","subitem_description_type":"Other"}]},"item_41_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"YOSHIKAWA, Shuhei"}]},{"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":"岩手大学農学部, 岩手大学大学院農学研究科"},{"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":"吉川, 秀平"}],"nameIdentifiers":[{}]},{"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-n45p57-71.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"biuf-n45p57-71.pdf","url":"https://iwate-u.repo.nii.ac.jp/record/9035/files/biuf-n45p57-71.pdf"},"version_id":"07cc96e4-51e6-4dd6-ba31-6bade9908edb"}]},"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":"スギ人工林における周辺林分や林地生産力の違いが下層木本の組成やサイズに及ぼす影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"スギ人工林における周辺林分や林地生産力の違いが下層木本の組成やサイズに及ぼす影響"}]},"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":"9035","relation_version_is_last":true,"title":["スギ人工林における周辺林分や林地生産力の違いが下層木本の組成やサイズに及ぼす影響"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T11:17:53.628262+00:00"}
