However,\nit was also found that as of today there is no particular\ntheoretical equation expressing the growth of individual\ntrees, and thus it was concluded that the available best\nfor describing the growth of individual trees was the general\ntheoretical equation. In chapter III, the characteristics\nof the three general theoretical equations thus chosen. i.e.,\nthe Mitscherlich, the logistic and the Gornpertz were discussed\nfrom an a priori theoretical point of view.\n In further pursuit of the most prospective growth\nequations for trees, the three general theoreticals were\napplied to the radial stem growth of 84 white spruce trees\nin chapter IV. It turned out that although all the equations\ndid not work in application as satisfactorily as expected\nfrom the theory, the Mitscherlich revealed the least\ntheoretical discrepancy, while the logistic did the most.\nThe best graphical agreement with the observed growth was\nattained by the Gompertz, followed by the Mitscherlich, then\nby the logistic. The easiest to fit was the Mitscherlich,\nfollowed by the logistic, then by the Gompertz.\n A similar analysis as in chapter IV was conducted\nwith 349 individual growth records of jack pine in chapter\nV. All the equations worked better with jack pine than with\nwhite spruce in every criterion employed. The most remarkable\nimprovement was achieved by the Mitscherlich. It revealed\nthe least theoretical discrepancy. while the logistic did\nthe most as with white spruce. The best graphical agreement\nwith the observed growth was achieved by the Mitscherlich \nfollowed by the Gompertz, then by the logistic. The\neasiest to fit was the Mitscherlich followed by the Gompertz,\nthen by the logistic. As an overall conclusion of chapters\nIV and V, at the present state of knowledge the best growth\nequation to describe the growth of trees in stem radius\nwould be the Mitscherlich.\n The last two chapter of the present work is devoted\nto the second objective, i.e., the application of the\ntheory of the growth equation to the other important subjects\nof mensuration, i.e., the stem taper curve and the height-diameter \ncurve. Assuming that the growth of individual\ntrees in stem diameter and height follows the Mitscherlich\nequation, a theoretial stem taper curve was derived mathematically.\nSubsequently it was compared with 50 observed\nstem taper curves and its theoretical compatibility was\ndiscussed. The proposed stem taper curve was also compared\nwith other existing empirical stem taper curves in terms of\nthe goodness of fit to 50 observed taper curves. It turned\nout that the ten equations compared were separated into five\ngroups singificantly differing from each other\u2032 of which\nthe proposed equation fell into the second best group.\n Again assuming that the growth of individual trees\nin stem diameter and height follows the Mitscherlich equation,\na heiqht-diameter curve for all-aged stands was derived.\nThen based on a similar but slightly different\nassumption, another height-diameter curve for even-aged\nstand was derived. Both equations are identical in their\nmathematical appearance but are different in what they\nmean.", "subitem_description_type": "Abstract"}]}, "item_12_description_5": {"attribute_name": "\u5185\u5bb9\u8a18\u8ff0", "attribute_value_mlt": [{"subitem_description": "\u540d\u53e4\u5c4b\u5927\u5b66\u535a\u58eb\u5b66\u4f4d\u8ad6\u6587 \u5b66\u4f4d\u306e\u7a2e\u985e:\u8fb2\u5b66\u535a\u58eb(\u8ad6\u6587) \u5b66\u4f4d\u6388\u4e0e\u5e74\u6708\u65e5:\u662d\u548c56\u5e741\u670813\u65e5", "subitem_description_type": "Other"}]}, "item_12_dissertation_number_65": {"attribute_name": "\u5b66\u4f4d\u6388\u4e0e\u756a\u53f7", "attribute_value_mlt": [{"subitem_dissertationnumber": "13901\u4e59\u7b2c1946\u53f7"}]}, "item_12_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/12550"}]}, "item_12_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_12_text_14": {"attribute_name": "\u30d5\u30a9\u30fc\u30de\u30c3\u30c8", "attribute_value_mlt": [{"subitem_text_value": "application/pdf"}, {"subitem_text_value": "application/pdf"}]}, "item_12_text_63": {"attribute_name": "\u5b66\u4f4d\u6388\u4e0e\u5e74\u5ea6", "attribute_value_mlt": [{"subitem_text_value": "1980"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "\u672b\u7530, \u9054\u5f66"}], "nameIdentifiers": [{"nameIdentifier": "32209", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Sweda, Tatsuo"}], "nameIdentifiers": [{"nameIdentifier": "32210", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-02-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "ot1946.pdf", "filesize": [{"value": "8.1 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 8100000.0, "url": {"label": "ot1946.pdf ", "url": "https://nagoya.repo.nii.ac.jp/record/10692/files/ot1946.pdf"}, "version_id": "fec9e0bc-c4a3-4fbd-b7ee-4f20edeea2b1"}, {"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-02-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 1, "filename": "ot1946_abstr.pdf", "filesize": [{"value": "248.8 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 248800.0, "url": {"label": "ot1946_abstr.pdf ", "url": "https://nagoya.repo.nii.ac.jp/record/10692/files/ot1946_abstr.pdf"}, "version_id": "14eb209a-72d4-48d2-b60b-c1dab8886d37"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "thesis", "resourceuri": "http://purl.org/coar/resource_type/c_46ec"}]}, "item_title": "Theoretical growth equations and their applications in forestry", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Theoretical growth equations and their applications in forestry"}]}, "item_type_id": "12", "owner": "1", "path": ["643/644/645"], "permalink_uri": "http://hdl.handle.net/2237/12550", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2009-12-24"}, "publish_date": "2009-12-24", "publish_status": "0", "recid": "10692", "relation": {}, "relation_version_is_last": true, "title": ["Theoretical growth equations and their applications in forestry"], "weko_shared_id": null}
