However, denuded areas in some years seemed to be large due to differences between the photographs, even though all of the photographs were transformed using the same scale. Even if the method applied in this study is qualitative analysis and incomplete in orthophotograph, change of bare land area during 60 year is clearly presented as distribution information. The method used in this study is manual and simple but effective for obtaining orthophotograph images that can be used to describe long-term change in forest cover and bare land area.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"54326","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ariyakanon, N."}]},{"nameIdentifiers":[{"nameIdentifier":"54327","nameIdentifierScheme":"WEKO"}],"names":[{"name":"沼本, 晋也"}]},{"nameIdentifiers":[{"nameIdentifier":"54328","nameIdentifierScheme":"WEKO"}],"names":[{"name":"鈴木, 雅一"}]}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学大学院農学生命科学研究科附属演習林"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162451","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03716007","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"610","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"The Tokyo University Forests"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学大学院農学生命科学研究科　森林科学専攻"},{"subitem_text_value":"Department of Forest Science, Graduate School of Agricultural and Life Sciences, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"ARIYAKANON, Naiyanan"}],"nameIdentifiers":[{"nameIdentifier":"54323","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"NUMAMOTO, Shinya"}],"nameIdentifiers":[{"nameIdentifier":"54324","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"SUZUKI, Masakazu"}],"nameIdentifiers":[{"nameIdentifier":"54325","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-09"}],"displaytype":"detail","filename":"esrh103008.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh103008.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25369/files/esrh103008.pdf"},"version_id":"88d9a2a3-e85c-4974-9b85-862c81f56531"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"裸地面積率","subitem_subject_scheme":"Other"},{"subitem_subject":"植生回復","subitem_subject_scheme":"Other"},{"subitem_subject":"航空写真解析","subitem_subject_scheme":"Other"},{"subitem_subject":"bare land ratio","subitem_subject_scheme":"Other"},{"subitem_subject":"vegetation recovery","subitem_subject_scheme":"Other"},{"subitem_subject":"aerial photography","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Sixty-year Decreasing Trend of Bare Land in Shirasaka Watershed, University Forest in Aichi, Revealed by Aerial Photography","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Sixty-year Decreasing Trend of Bare Land in Shirasaka Watershed, University Forest in Aichi, Revealed by Aerial Photography"}]},"item_type_id":"4","owner":"1","path":["2536","2535"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-07-17"},"publish_date":"2012-07-17","publish_status":"0","recid":"25369","relation_version_is_last":true,"title":["Sixty-year Decreasing Trend of Bare Land in Shirasaka Watershed, University Forest in Aichi, Revealed by Aerial Photography"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:59:35.039757+00:00"}
