The survey was conducted in 63 clear-cut areas and the results showed that the average density of skidding roads was 361 m/ha, which was high, regardless of the ground slope of the clear-cut area. The study results in terms of average yarding distance, road layout, and the yarding method suggested that an excessive number of roads were established. This is because they did not contribute to the network development even though they were established at high density. Furthermore, 168 points of filling collapse were observed in the skidding roads, and the risk of filling collapse was very high on steep slopes with a slope of 30° or more. Several yarding roads were established in the steep slopes, and many roads were not easy to use continuously due to the filing collapse. Additionally, the percentage of forest land devastation related to skidding roads was large.","subitem_description_type":"Other"}]},"item_16_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"96048","nameIdentifierScheme":"WEKO"}],"names":[{"name":"IKOMA, Nao"}]},{"nameIdentifiers":[{"nameIdentifier":"96049","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SAITO, Masashi"}]},{"nameIdentifiers":[{"nameIdentifier":"96050","nameIdentifierScheme":"WEKO"}],"names":[{"name":"TATSUKAWA, Shiro"}]}]},"item_16_link_13":{"attribute_name":"抄録（URL）","attribute_value_mlt":[{"subitem_link_text":"車両系皆伐作業における集材路の実態把握","subitem_link_url":"https://www.jstage.jst.go.jp/article/jjfes/37/1/37_37.39/_article/-char/ja/"}]},"item_16_publisher_14":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"森林利用学会"}]},"item_16_relation_26":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.18945/jjfes.37.39","subitem_relation_type_select":"DOI"}}]},"item_16_rights_18":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2022 森林利用学会"}]},"item_16_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"21896658","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"13423134","subitem_source_identifier_type":"ISSN"}]},"item_16_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"岩手大学大学院総合科学研究科"},{"subitem_text_value":"岩手大学農学部"},{"subitem_text_value":"岩手大学農学部"}]},"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":"生駒, 直"}],"nameIdentifiers":[{"nameIdentifier":"95595","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"齋藤, 仁志"}],"nameIdentifiers":[{"nameIdentifier":"95596","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"立川, 史郎"}],"nameIdentifiers":[{"nameIdentifier":"95597","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":"2023-01-12"}],"displaytype":"detail","filename":"jjfes-v37n1p39-46.pdf","filesize":[{"value":"1.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"jjfes-v37n1p39-46","url":"https://iwate-u.repo.nii.ac.jp/record/15884/files/jjfes-v37n1p39-46.pdf"},"version_id":"ac450244-fdec-4004-81b8-fc3d3475818e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"皆伐","subitem_subject_scheme":"Other"},{"subitem_subject":"集材路","subitem_subject_scheme":"Other"},{"subitem_subject":"路網密度","subitem_subject_scheme":"Other"},{"subitem_subject":"盛土崩壊","subitem_subject_scheme":"Other"},{"subitem_subject":"林地荒廃","subitem_subject_scheme":"Other"},{"subitem_subject":"clear cutting, skidding road, forest road density, slope failure of embankment, degraded forest land","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"車両系皆伐作業における集材路の実態把握","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"車両系皆伐作業における集材路の実態把握"},{"subitem_title":"Grasping the actual state of skidding road in clear cutting with a vehicle logging system.","subitem_title_language":"en"}]},"item_type_id":"16","owner":"19","path":["1510"],"pubdate":{"attribute_name":"公開日","attribute_value":"2023-01-12"},"publish_date":"2023-01-12","publish_status":"0","recid":"15884","relation_version_is_last":true,"title":["車両系皆伐作業における集材路の実態把握"],"weko_creator_id":"19","weko_shared_id":-1},"updated":"2023-05-15T12:39:28.798633+00:00"}
