To compare rentability of the broad-leaved forest and the Ryukyu-matsu (Pinus luchuensis Mayr) forest, the author calculated the expectation value of forest land and index percent. Necessary factors are decided as follows: 1) The least diameter of the breast height of log is 12 cm. 2) Lumber percentage are 50％ in 30 years and 60％ in 35 years in the broad-leaved tree, and the percentage of other age prescribed accordingly. The percentage of the Ryukyu-matsu added 10％ to the broad-leaved tree. 3) The percentage to be utilized for fuel is the remainder of 90％, the value of the tree for utilization. 4) Price of Ryukyu-matsu per 1 m^3 in the lumber is $ 5.00 of 20 years of age and $ 9.00 of 40 years, and as to the broad-leaved tree, $ 4.50 in 20 years and $ 6.50 in 40 years. The price of tree of other ages are prescribed accordingly. The price of the both kinds. of trees for fuelwood are $ 0.15. 5) The expenditure per 1 ha of Ryukyu-matsu as $134.50 and that of the broad-leaved tree is $18.00. 6) Forest management expence is $ 3.00. 7) The rate of interrest is 6％. 8) The value of land is considered from both the net value of forest soil and the estimated land value, $150.00. 2. The suitable final age of the Ryukyu-matsu is 25 to 35 years, and that of the broad-leaved tree, 25 to 30 years. 3. The economical maximum utilization period of land for the Ryukyu-matsu is 35 years and 30 years for the broad-leaved tree. The return from final cutting in these periods are $1620.25 for the Ryukyu-matsu, $703.80 for the broad-leaved tree when tendered and $535.50 when untendered. The expectation value of land is $197.22, $76.57 and $62.88 respectively. The Ryukyu-matsu is better than the broad-leaved tree for rentability. However, when the management of the Ryukyu-matsu is unproper, the return from final cuttings of it is greater than that of the broad-leaved trees, the rentability may be smaller. Therefore, it is necessary to consider whether to plant the Ryukyu-matsu or not in the remote land.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学農家政工学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/19327"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0485-7828"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00250570"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学農家政工学部学術報告"},{"subitem_1522650068558":"en","subitem_1522650091861":"The science bulletin of the Division of Agriculture, Home Economics & Engineering, University of the Ryukyus"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueNumber":"11","bibliographicPageEnd":"108","bibliographicPageStart":"102"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_1522305645492":"NA","subitem_1600292170262":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"No11p102.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2005831/files/No11p102.pdf"},"version_id":"c58dc533-7229-4ea4-b3e8-efe4657d9497"}]},"item_title":"壮令広葉樹林分と壮令リュウキュウマツ林分との収益性試算","item_type_id":"15","owner":"1","path":["1642837936199","1642838406845"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2011-04-26"},"publish_date":"2011-04-26","publish_status":"0","recid":"2005831","relation_version_is_last":true,"title":["壮令広葉樹林分と壮令リュウキュウマツ林分との収益性試算"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-02-15T03:12:16.222874+00:00"}
