Therefore, the relationship between the water behavior and the change of physical properties in forest surface soil was investigated. Soil samples were collected in about 30 years old stand of hinoki, Chamaecyparis obtusa S. and in about 80 years old stand of sugi, Cyptomeria japonica D.Don On the assumption that the forest was clearly cut, these soil samples were exposed to the change in quality through the irradiation of artificial sunrays by using the weather meter. Comparing the volume of each pore size of surface soil before and after the irradiation, the quantity of larger pore size, which is related to the movement of gravitatinal water, increased after the irradiation, and that of smaller pore size, which is related to the soil retention storage, decreased. The degree of aggregation of surface soil also decreased after the irradiation. These influences were more remarkable in stand of sugi than hinoki. If the physical properties of surface soil change through the clear cutting of forest, it is estimated that more infiltrated water would rapidly more downward and cause the decrease of soil shear resistance related to the occurrence of landslide.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_9_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"農林水産研究情報センターで作成したPDFファイルを使用している。","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_9_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/8673"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18999/bulnuf.10.65","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"名古屋大学農学部付属演習林","subitem_publisher_language":"ja"}]},"item_9_relation_43":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://rms1.agsearch.agropedia.affrc.go.jp/contents/JASI/pdf/academy/46-0852.pdf","subitem_relation_type_select":"URI"}}]},"item_9_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_9_source_id_7":{"attribute_name":"ISSN（print）","attribute_value_mlt":[{"subitem_source_identifier":"0469-4708","subitem_source_identifier_type":"PISSN"}]},"item_9_text_14":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_text_value":"application/pdf"}]},"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":[{"creatorNames":[{"creatorName":"竹田, 泰雄","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"18812","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"TAKEDA, Yasuo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"18813","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"アルンシリ, カムラン","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"18814","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"KUMLUNG, Arunsiri","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"18815","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":"2018-02-19"}],"displaytype":"detail","filename":"bulnuf_10_65.pdf","filesize":[{"value":"581.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"bulnuf_10_65.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/7002/files/bulnuf_10_65.pdf"},"version_id":"7b479b60-f3a3-4156-8270-f2a8c0e061bb"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"土壌間隙","subitem_subject_scheme":"Other"},{"subitem_subject":"団粒構造","subitem_subject_scheme":"Other"},{"subitem_subject":"ウェザーメーター","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":"森林の崩壊防止機能における林地表層土壌の評価 (I) : 人工太陽光照射による林地表層土壌の変質","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"森林の崩壊防止機能における林地表層土壌の評価 (I) : 人工太陽光照射による林地表層土壌の変質","subitem_title_language":"ja"}]},"item_type_id":"9","owner":"1","path":["866"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-08-17"},"publish_date":"2007-08-17","publish_status":"0","recid":"7002","relation_version_is_last":true,"title":["森林の崩壊防止機能における林地表層土壌の評価 (I) : 人工太陽光照射による林地表層土壌の変質"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-16T04:17:12.480657+00:00"}
