Ireland), L.Balaton (Hungary) and L.Suwa (Japan). The water quality in each lake has undergone marked deteriorations during this century and all of them were considered hypertrophic by the late 1970\u0027s. Improved sewage treatment was installed and although they all showed some initial recovery (max. chl a down by 25 - 33% by 1984), since then further improvement has been much slower. Two of the main reasons for this are internal recycling and the in-wash of nutrients from non-point sources. In considering the restoration plans for the three lakes, it is important to include inshore areas. Each of these lakes has been lowered and their annual water level fluctuations controlled. To highlight the major ecological problems associated with such changes, L.Neagh, which has a largely \u0027undeveloped\u0027 shoreline but where rare post-glacial habitats are endangered, is compared to L.Balaton, now one of Central Europe\u0027s most popular resorts.", "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_31": {"attribute_name": "フォーマット：mimeタイプ", "attribute_value_mlt": [{"subitem_description": "application/pdf", "subitem_description_type": "Other"}]}, "item_10_description_5": {"attribute_name": "引用", "attribute_value_mlt": [{"subitem_description": "信州大学理学部付属諏訪臨湖実験所報告 7: 9-19(1991)", "subitem_description_type": "Other"}]}, "item_10_publisher_4": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "信州大学理学部"}]}, "item_10_select_64": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_10_source_id_40": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00089817", "subitem_source_identifier_type": "NCID"}]}, "item_10_text_66": {"attribute_name": "sortkey", "attribute_value_mlt": [{"subitem_text_value": "02"}]}, "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": "Jewson,  D.H.", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "47003", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Zlinszky,  J.", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "47004", "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": "2015-09-28"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "Suwa07-02.pdf", "filesize": [{"value": "700.3 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 700300.0, "url": {"label": "Suwa07-02.pdf", "url": "https://soar-ir.repo.nii.ac.jp/record/16435/files/Suwa07-02.pdf"}, "version_id": "0199343a-00af-4952-ac6a-4a56ec84773e"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "eutrophication", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "lake restoration", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "internal recycling", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "bioturbation", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "lake margins", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "water levels", "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 PROBLEMS OF RESTORING LARGE, SHALLOW LAKES.", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "THE PROBLEMS OF RESTORING LARGE, SHALLOW LAKES.", "subitem_title_language": "en"}]}, "item_type_id": "10", "owner": "1", "path": ["1614"], "permalink_uri": "http://hdl.handle.net/10091/1942", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2009-02-27"}, "publish_date": "2009-02-27", "publish_status": "0", "recid": "16435", "relation": {}, "relation_version_is_last": true, "title": ["THE PROBLEMS OF RESTORING LARGE, SHALLOW LAKES."], "weko_shared_id": -1}
