Total annual emission of nitrogen from fertilizers, livestock wastes, and domestic wastes at Miyako Island, Okinawa was examined from 1977 to 1998, and compared with the concentration of nitrogen in groundwater. The trend of nitrogen emission was reflected on the groundwater concentration with the delay of seven years. This suggests that the velocity of nitrogen permeating down to the groundwater is 3 m per year. The amount of nitrogen leaching into the groundwater was 39% of the total nitrogen emission on the ground. These results emphasize the importance of data collection on nitrogen emission in order to predict the future nitrogen concentration of groundwater in coral islands.","subitem_description_type":"Other"}]},"item_9_description_9":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_9_publisher_10":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"日本水環境学会"}]},"item_9_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本水環境学会"}]},"item_9_source_id_6":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0387-2025","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"0916-8958","subitem_source_identifier_type":"ISSN"}]},"item_9_text_11":{"attribute_name":"公開者別名","attribute_value_mlt":[{"subitem_text_value":"Japan Society on Water Environment"}]},"item_9_text_15":{"attribute_name":"タイプ","attribute_value_mlt":[{"subitem_text_value":"論文"}]},"item_9_text_16":{"attribute_name":"NIIタイプ","attribute_value_mlt":[{"subitem_text_value":"Journal Article"}]},"item_9_text_17":{"attribute_name":"DCMI","attribute_value_mlt":[{"subitem_text_value":"text"}]},"item_9_text_18":{"attribute_name":"収録種別","attribute_value_mlt":[{"subitem_text_value":"雑誌掲載論文"}]},"item_9_text_19":{"attribute_name":"収録種別","attribute_value_mlt":[{"subitem_text_value":"01"}]},"item_9_text_20":{"attribute_name":"収録雑誌名","attribute_value_mlt":[{"subitem_text_value":"水環境学会誌 = Journal of Japan Society on Water Environment"}]},"item_9_text_21":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_text_value":"AN10372439"}]},"item_9_text_25":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"沖縄県公衆衛生協会"},{"subitem_text_value":"Okinawa Prefecture Public Health Association"}]},"item_9_text_4":{"attribute_name":"別言語の著者","attribute_value_mlt":[{"subitem_text_value":"TASHIRO, Yutaka"},{"subitem_text_value":"TAKAHIRA, Kaneshi"}]},"item_9_text_5":{"attribute_name":"作成日","attribute_value_mlt":[{"subitem_text_value":"2001-11-10"}]},"item_9_version_type_24":{"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":"田代, 豊"}],"nameIdentifiers":[{"nameIdentifier":"2463","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高平, 兼司"}],"nameIdentifiers":[{"nameIdentifier":"2464","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":"2020-12-03"}],"displaytype":"detail","filename":"Vol24No11p733.pdf","filesize":[{"value":"657.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Vol24No11p733.pdf","url":"https://meio-u.repo.nii.ac.jp/record/1156/files/Vol24No11p733.pdf"},"version_id":"0636af4f-835c-4156-bee2-3986544145e0"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"nitrogen pollution","subitem_subject_scheme":"Other"},{"subitem_subject":"groundwater","subitem_subject_scheme":"Other"},{"subitem_subject":"coral island","subitem_subject_scheme":"Other"},{"subitem_subject":"water permeation","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":"宮古島における窒素負荷発生量と地下水窒素濃度の長期的推移","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"宮古島における窒素負荷発生量と地下水窒素濃度の長期的推移"}]},"item_type_id":"9","owner":"1","path":["63"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-08-21"},"publish_date":"2012-08-21","publish_status":"0","recid":"1156","relation_version_is_last":true,"title":["宮古島における窒素負荷発生量と地下水窒素濃度の長期的推移"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T10:26:53.310168+00:00"}
