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\uff05 in 30 years and 60\uff05 in 35 years in the broad-leaved tree, and the percentage of other age prescribed accordingly. The percentage of the Ryukyu-matsu added 10\uff05 to the broad-leaved tree. 3) The percentage to be utilized for fuel is the remainder of 90\uff05, 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\uff05. 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": "\u7d00\u8981\u8ad6\u6587", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "\u7409\u7403\u5927\u5b66\u8fb2\u5bb6\u653f\u5de5\u5b66\u90e8"}]}, "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": "\u7409\u7403\u5927\u5b66\u8fb2\u5bb6\u653f\u5de5\u5b66\u90e8\u5b66\u8853\u5831\u544a"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "The science bulletin of the Division of Agriculture, Home Economics \u0026 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", "download_preview_message": "", "file_order": 0, "filename": "No11p102.pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 0, "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": "\u58ee\u4ee4\u5e83\u8449\u6a39\u6797\u5206\u3068\u58ee\u4ee4\u30ea\u30e5\u30a6\u30ad\u30e5\u30a6\u30de\u30c4\u6797\u5206\u3068\u306e\u53ce\u76ca\u6027\u8a66\u7b97", "item_type_id": "15", "owner": "1", "path": ["1642837936199", "1642838406845"], "permalink_uri": "http://hdl.handle.net/20.500.12000/19327", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2011-04-26"}, "publish_date": "2011-04-26", "publish_status": "0", "recid": "2005831", "relation": {}, "relation_version_is_last": true, "title": ["\u58ee\u4ee4\u5e83\u8449\u6a39\u6797\u5206\u3068\u58ee\u4ee4\u30ea\u30e5\u30a6\u30ad\u30e5\u30a6\u30de\u30c4\u6797\u5206\u3068\u306e\u53ce\u76ca\u6027\u8a66\u7b97"], "weko_shared_id": -1}
