Each section of the lysimeter was filled with the same soil materials and has a width of 3m, a length of 6 m, and is 2.5 m deep. Its slope angle is 20 degrees. In this study, the surface runoff characteristics of two sections were compared, one of which had stone mulching and the other of which was bare surface. Initially, one bare section was covered with stone mulching and the other was left bare. Halfway through the investigation period, all of the stones on the section with stone mulching were removed and put on the other section which had previously been bare. The results show that surface runoff from a bare section is immediately reduced by stone mulching on the ground surface. When the stones used for stone mulching are removed from the section, its surface runoff characteristics gradually return to those of a bare section. It is thought that rain-drop impact compacts the soil surface and gradually reduces infiltration, whereas stone mulching breaks the rain-drop size down and makes infiltration increase immediately.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"54286","nameIdentifierScheme":"WEKO"}],"names":[{"name":"NAGAI, Takemo"}]},{"nameIdentifiers":[{"nameIdentifier":"54287","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SHIRAKI, Katsushige"}]},{"nameIdentifiers":[{"nameIdentifier":"54288","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KUMAGAI, Tomo'omi"}]},{"nameIdentifiers":[{"nameIdentifier":"54289","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SUZUKI, Masakazu"}]},{"nameIdentifiers":[{"nameIdentifier":"54290","nameIdentifierScheme":"WEKO"}],"names":[{"name":"OHTA, Takehiko"}]}]},"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":"東京農工大学農学部"},{"subitem_text_value":"九州大学農学部附属演習林"},{"subitem_text_value":"東京大学大学院農学生命科学研究科農学国際専攻"},{"subitem_text_value":"Department of Forest Science, Graduate School of Agricultural and Life Sciences, The University of Tokyo"},{"subitem_text_value":"Faculty of Agriculture, Tokyo University of Agriculture and Technology"},{"subitem_text_value":"University Forest, Faculty of Agriculture, Kyushu University"},{"subitem_text_value":"Department of Global Agricultural Sciences, 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":"永井, 壯茂"}],"nameIdentifiers":[{"nameIdentifier":"54281","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"白木, 克繁"}],"nameIdentifiers":[{"nameIdentifier":"54282","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"熊谷, 朝臣"}],"nameIdentifiers":[{"nameIdentifier":"54283","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鈴木, 雅一"}],"nameIdentifiers":[{"nameIdentifier":"54284","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"太田, 猛彦"}],"nameIdentifiers":[{"nameIdentifier":"54285","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":"esrh103003.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh103003.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25364/files/esrh103003.pdf"},"version_id":"a05e37c9-c39f-4a64-b9c2-8ee727bddac8"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"表面流出","subitem_subject_scheme":"Other"},{"subitem_subject":"ライシメータ","subitem_subject_scheme":"Other"},{"subitem_subject":"裸地斜面","subitem_subject_scheme":"Other"},{"subitem_subject":"ストーンマルチ","subitem_subject_scheme":"Other"},{"subitem_subject":"surface runoff","subitem_subject_scheme":"Other"},{"subitem_subject":"lysimeter","subitem_subject_scheme":"Other"},{"subitem_subject":"bare ground slope","subitem_subject_scheme":"Other"},{"subitem_subject":"stone mulching","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":"裸地斜面へのストーンマルチが表面流出形成に与える影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"裸地斜面へのストーンマルチが表面流出形成に与える影響"}]},"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":"25364","relation_version_is_last":true,"title":["裸地斜面へのストーンマルチが表面流出形成に与える影響"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:39.419603+00:00"}
