The highest total nitrogen removal efficiency was using 94.8% of All. The highest total phosphorus removal efficiency was 85.1% of Typha angustifolia. The effects of floating islands ont the changes in phytoplankton community structure were investigated in a small artificial pond. The floating islands planted with various emergent macrophytes coverd 35% of total water surface area of the pond. Total 17 genera and 25 species of phytoplankton were found in the pond, of which Dinophyceae was 1 genera and 1species, Cyanophyceae 1 genera and 1 species, Bacillariophycear 6 genera and 8 species, and Chlorophyceae 9 genera and 15 species. Dominant phytoplnaktons under floating islands were changes from Aphanizomenon sp. as a Cyanophycear for 56 days after the construction of floating islands on July 24, 2001. The changes of dominant phytoplanktons of the control without floating islands were similar to those under floating islands in July and August, but Aphanizomenon sp. was rapidly increased in the control sites in September. About 99% of the cell number of Aphanizomenon sp. was disappeared for a month after construction of floating islands. Our results showed that the floating islands could be a useful eco-technique for the control of water bloom by Cyanophyceae and Chlorophyceae in a pond ecosystem.","subitem_description_type":"Abstract"}]},"item_10_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_10_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"信州大学山地水環境教育研究センター研究報告 2: 121-126(2004)","subitem_description_type":"Other"}]},"item_10_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"信州大学山地水環境教育研究センター"}]},"item_10_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1348-7612","subitem_source_identifier_type":"ISSN"}]},"item_10_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11887942","subitem_source_identifier_type":"NCID"}]},"item_1627890569677":{"attribute_name":"出版タイプ","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":"Eun, Joo, LEE","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Oh, Byung, KWON","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-28"}],"displaytype":"detail","filename":"InlandWater02-23.pdf","filesize":[{"value":"504.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"InlandWater02-23.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/16365/files/InlandWater02-23.pdf"},"version_id":"e59435b7-6b0a-4b0d-b4cb-eb42d5c5b964"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Hydrophytes","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Cyanophyceae","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Plant floating island","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Phytoplankton","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"The effects of floating islands planted with various hydrophytes for water quality improvement","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"The effects of floating islands planted with various hydrophytes for water quality improvement","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["1606"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-02-27"},"publish_date":"2009-02-27","publish_status":"0","recid":"16365","relation_version_is_last":true,"title":["The effects of floating islands planted with various hydrophytes for water quality improvement"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-03-09T01:26:01.158072+00:00"}
