This is based mainly on the result of “The Fourth National Survey on the Natural Environment conducted by EPA Japan. We took a part in the research on natural lakes in Nagano pref.For this investigation，39 lakes having as urface area larger than 0.01 km' were selected. These many lakeslocate in the northern part of Nagano area. According to the trophic state，39 lakes were classified into five groups (eutrophic: 8，m esotrophic: 13，o ligotrophic: 13，a cidtrophic: 2a nd dystrophic :3) . The natural state of lake environment was judged based on the ratio of the length of natural shore line to the whole length of its shore line. The lake located over 1，500 m have been preserved mostly in the natural state. Most of them were located in special protection areas such as a national park. The lake environment at the lower altitude tends to deteriorate. For example，t he shore line more than 95% of Suwa-ko and Fukami北e(759 and 484 m in altitude，re spectively) has been embanked artificialy The present state of lake environment in N agano prefecture is shown by the parameters related to water quality，s uch as transparency，C hlorophyll-a，C OD，n itrogen and phosphorus.","subitem_description_type":"Other"}]},"item_20009_description_20":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_20009_description_21":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_20009_description_22":{"attribute_name":"その他の資源識別子","attribute_value_mlt":[{"subitem_description":"環境科学年報17:51-62(1995)","subitem_description_type":"Other"}]},"item_20009_full_name_16":{"attribute_name":"公開者(その他言語)","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"信州大学環境科学研究会"}]}]},"item_20009_identifier_23":{"attribute_name":"資源識別子URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/10091/12407"}]},"item_20009_source_id_25":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0915-7492","subitem_source_identifier_type":"ISSN"}]},"item_20009_source_id_26":{"attribute_name":"処理レコードID(総合目録DB)","attribute_value_mlt":[{"subitem_source_identifier":"AN1054947X","subitem_source_identifier_type":"NCID"}]},"item_20009_version_type_51":{"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_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"url":{"url":"https://soar-ir.repo.nii.ac.jp/?action=repository_action_common_download&item_id=16848&item_no=1&attribute_id=65&file_no=1"}}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Nagano Prefecture","subitem_subject_scheme":"Other"},{"subitem_subject":"lake environment","subitem_subject_scheme":"Other"},{"subitem_subject":"eutrophication","subitem_subject_scheme":"Other"},{"subitem_subject":"water quality","subitem_subject_scheme":"Other"},{"subitem_subject":"長野県","subitem_subject_scheme":"Other"},{"subitem_subject":"湖沼環境","subitem_subject_scheme":"Other"},{"subitem_subject":"富栄養化","subitem_subject_scheme":"Other"},{"subitem_subject":"水質","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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"長野県におげる湖沼環境の現状 : 1991年の調査から","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"長野県におげる湖沼環境の現状 : 1991年の調査から"}]},"item_type_id":"20009","owner":"3","path":["2668"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-09-04"},"publish_date":"2020-09-04","publish_status":"0","recid":"39201","relation_version_is_last":true,"title":["長野県におげる湖沼環境の現状 : 1991年の調査から"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-05-15T19:09:53.555455+00:00"}
