The number of machines has risen to over 300 according to the Japanese Ministry of Forestry Agency. In this paper we introduce an outline and results of a trial thinning system using a harvester and a forwarder in non-mountainous forest in Hokkaido. Thinning was performed by the line thinning method cutting one line in four in a 27 years old Sagahalien fir forest. This had been planted using the four line group system, so-called \"Shijyou Planting\". The slope of the forest land is under 10 degrees. The trial gave very good results. The productivities were 20-30 m3/system day for the harvester and 30-50 m3/system for the forwarder. We can say that this thinning system using a harvester and a forwarder has already become established for thinning in the above mentioned forest.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"54886","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KOBAYASHI, Hiroshi"}]},{"nameIdentifiers":[{"nameIdentifier":"54887","nameIdentifierScheme":"WEKO"}],"names":[{"name":"IWAOKA, Masahiro"}]},{"nameIdentifiers":[{"nameIdentifier":"54888","nameIdentifierScheme":"WEKO"}],"names":[{"name":"NITAMI, Toshio"}]}]},"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":"東京大学農学部林学科"},{"subitem_text_value":"東京大学農学部附属演習林研究部"},{"subitem_text_value":"Department of Forestry, Faculty of Agriculture, The University of Tokyo"},{"subitem_text_value":"Research Division of The University Forests, Faculty of Agriculture, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小林, 洋司"}],"nameIdentifiers":[{"nameIdentifier":"54883","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"岩岡, 正博"}],"nameIdentifiers":[{"nameIdentifier":"54884","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"仁多見, 俊夫"}],"nameIdentifiers":[{"nameIdentifier":"54885","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":"esrh089002.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh089002.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25470/files/esrh089002.pdf"},"version_id":"ea3b54a2-8dab-4262-9718-cdfb1452919f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"列状間伐","subitem_subject_scheme":"Other"},{"subitem_subject":"高性能林業機械","subitem_subject_scheme":"Other"},{"subitem_subject":"ハーベスタ","subitem_subject_scheme":"Other"},{"subitem_subject":"フォーワーダ","subitem_subject_scheme":"Other"},{"subitem_subject":"Line thinning","subitem_subject_scheme":"Other"},{"subitem_subject":"High quality forest machine","subitem_subject_scheme":"Other"},{"subitem_subject":"Harvester","subitem_subject_scheme":"Other"},{"subitem_subject":"Forwarder","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ハーベスタとフォワーダによる間伐材搬出作業システム","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ハーベスタとフォワーダによる間伐材搬出作業システム"}]},"item_type_id":"4","owner":"1","path":["2564","2563"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-09-03"},"publish_date":"2014-09-03","publish_status":"0","recid":"25470","relation_version_is_last":true,"title":["ハーベスタとフォワーダによる間伐材搬出作業システム"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:37.377157+00:00"}
