The information system is made up of two subsystems, a system yield table and an atlas of forest information. This paper consists of four parts. The first part systematically explains system yield table which is based on ideas developed at this university in this research. It gives the definitions and functions of the system yield table which can be applied to various stand structures and forest treatments, not only to predict yield but also to provide a decision support system for forest planning. Next, concepts based on a system yield table for Shinshu karamatsu (Larix kaempferi) even-aged stands is generalized and the procedure for constructing the system is developed. The procedure is: 1) determination of the object and policy, 2) collection and analysis of the data, 3) construction of a growth simulation system, and 4) development of the program. In the second patr, an atlas of forest information is constructed based on database. The atlas provides an easier understanding of the forest conditions in Hase village, Nagano prefecture. First, map information (e. g. forest map, soil map) and their attributes (e. g. forest register) were collected. Next, map information including lines and polygons were digitized and the attributes were data based. Finally, using GIS (Geo-graphic Information System) to link map information and their attributes, an atlas useful for forest management and planning was produced. In the third part, an information system for watershed forest management is developed, which integrates the system yield table with the atlas. The last part shows that a decision support system can be implemented using the information system. There are two application examples, which provide more practical information for watershed forest management and planning in the Tenryu River water-shed in Hase Village, Nagano Prefecture. The first example is an application of the best forest systems to Karamatsu stands for timber production. The atlas was used to divide the planning area into 4 working blocks, one each for large log production, middle log production, small log production and ecological conservation, based on contour lines, angles of declinations and inclinations, soil types and geographical criterion judging from whether or not the areas were within a certain distance from a forest road. The growth and the volume of yield and utilization were predicted for various thinning patterns and felling ages by a simulation model using the system yield table. The results were as follows: 1) Low thinning is the most suitable method. 2) Thinning is necessary every 10 to 15 years. 3) The rotation in maximum final mean annual increment of yield volume is about 50 years. 4) The rotation in maximum final mean annual increment of utilizing volume is about 50 years for class I and II sites, and about 60 years for class III site. The best felling ages were judged to be about 70 years for large and middle log production, and 60 years for small log production. The second example is a prediction of the future timber production for the next 5 periods (25 years) using the gentan probability. The prediction is based on the analysis of present harvesting patterns. Using the system yield table, log yield tables were constructed based on the best forest systems and thinned-log predicted taking accessibility. Timber production was forecast by log length and topdiameter class for both thinning and felling based on the log yield tables and the present age-class distributions. The results were as follows: 1) Future timber production is on the rapid increase. 2) Large log production is a possibility based on site quality. 3) Greater part of the prediction is yield of thinning. In this paper there are three original points. The first point is the establishment of a method to construct a system yield table. The second point is the development of an atlas of forest information to provide an easier understanding of forest conditions. The third point is the development of an information system for watershed forest manage-ment and planning. In summary, this paper develops methods which provides more practical information and decision support, and demonstrates the possibilities of a new useful system for watershed forest management and planning.", "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": "信州大学農学部演習林報告 32: 1-62(1995)", "subitem_description_type": "Other"}]}, "item_10_publisher_4": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "信州大学農学部附属演習林"}]}, "item_10_select_64": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_10_source_id_35": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0559-8613", "subitem_source_identifier_type": "ISSN"}]}, "item_10_source_id_39": {"attribute_name": "NII ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0559-8613", "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": "AN00121330", "subitem_source_identifier_type": "NCID"}]}, "item_10_text_66": {"attribute_name": "sortkey", "attribute_value_mlt": [{"subitem_text_value": "01"}]}, "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": "鄭,  小賢"}], "nameIdentifiers": [{"nameIdentifier": "35057", "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": "2015-09-25"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "Agri_Forests-32-01.pdf", "filesize": [{"value": "3.5 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 3500000.0, "url": {"label": "Agri_Forests-32-01.pdf", "url": "https://soar-ir.repo.nii.ac.jp/record/11204/files/Agri_Forests-32-01.pdf"}, "version_id": "60876456-ecb5-43ae-bcc2-7bf422aaa471"}]}, "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": "システム収穫表および森林情報アトラスに関する研究 : 流域森林管理情報システムの開発", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "システム収穫表および森林情報アトラスに関する研究 : 流域森林管理情報システムの開発", "subitem_title_language": "ja"}, {"subitem_title": "Studies on system yield table and an atlas of forest information : Development of an information system for watershed management", "subitem_title_language": "en"}]}, "item_type_id": "10", "owner": "1", "path": ["1110"], "permalink_uri": "http://hdl.handle.net/10091/14057", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2012-03-07"}, "publish_date": "2012-03-07", "publish_status": "0", "recid": "11204", "relation": {}, "relation_version_is_last": true, "title": ["システム収穫表および森林情報アトラスに関する研究 : 流域森林管理情報システムの開発"], "weko_shared_id": -1}
