In this research, I aimed to thin abandoned Japanese cedar and cypress forests and secondary broadleaf forests in the Soma region, one of the areas severely contaminated by radioactive fallout, observe the subsequent vegetation recovery, and make recommendations regarding future operations in the area. The research method was to thin 50% of the trees in each study stand from 2019 to 2022, compare the relative light intensity before and after thinning, and conduct a vegetation survey from June to October 2024 in four study areas of 10 meter x 10 meter (1are). Although seedlings of 30 to 50 tree species were found in each stand, their top growth was low, and the coverage of the forest floor was also low in Japanese cedar and cypress stands. The main reason for this was thought to be low light intensity due to canopy closure, and additional thinning was considered necessary. \nKeywords: relative illuminance, forest floor vegetation, coverage, seedlings, 50% thinning","subitem_description_language":"en","subitem_description_type":"Other"},{"subitem_description":"要旨:2011年3月の東日本大震災の発生以来,福島県内の各地にはいまなお放置された状態の山林が数多く存在している。本論文では,放射性降下物の汚染が甚大であった地域の一つである相馬地方のスギ,ヒノキの放置林および広葉樹二次林を対象地とし,それぞれ間伐をおこない,その後の植生回復を観察し,今後の当地における施業について提言することを目的とした。研究の方法は,各調査林分において50%の本数間伐を2019年~2022年に実施し,間伐前後の相対照度を比較し,それぞれ10 m×10 m(1a)の調査区を4か所ずつ設けて,2024年6~10月に植生調査をおこなった。各林分では30~50樹種前後の実生が見出されたものの,その上長成長は低く,スギ,ヒノキ林分においては林床の被覆度も低かった。その主な理由には林冠閉鎖による低照度が推察され,追加の間伐が必要と考えられた。 \nキーワード:相対照度,林床植生,被覆度,実生,50%間伐","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"関東森林学会","subitem_publisher_language":"ja"}]},"item_10001_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Tokyo University of Agriculture","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Iwao, UEHARA","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2025-05-09"}],"filename":"10287208_著者最終稿_20250306190625.pdf","filesize":[{"value":"490 KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"url":"https://nodai.repo.nii.ac.jp/record/2000433/files/10287208_著者最終稿_20250306190625.pdf"},"version_id":"299136bb-e22a-4d97-a9aa-b6293f7c922d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"相対照度","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"relative illuminance","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"林床植生","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"forest floor vegetation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"被覆度","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"coverage","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"実生","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"seedlings","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"50%間伐","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"50% thinning","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Thinning and subsequent vegetation changes in abandoned forests  in the Soma region of Fukushima Prefecture","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Thinning and subsequent vegetation changes in abandoned forests  in the Soma region of Fukushima Prefecture","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"51","path":["1725514122190"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2025-05-14"},"publish_date":"2025-05-14","publish_status":"0","recid":"2000433","relation_version_is_last":true,"title":["Thinning and subsequent vegetation changes in abandoned forests  in the Soma region of Fukushima Prefecture"],"weko_creator_id":"51","weko_shared_id":-1},"updated":"2025-05-26T04:57:03.705797+00:00"}
