間伐効果を検討した。間伐は, 上層間伐方式を採用した。胸高断面積合計の年平均成長量および成長率は, 対照区に比べて間伐区や間伐+施肥区で多く (高く) なる傾向があった。しかしながら, 施肥の効果はみられなかった。単木ごとの間伐直後の胸高直径と胸高断面積の年平均成長量や成長率の関係から, 小中径木ほど間伐効果が高い傾向が明らかで, 対照区に比べて間伐区 (間伐+施肥区) で胸高直径25 cm以上の大径木が増加した。間伐時に大きな直径階での間伐割合が高い林分で, 大径木の本数が増加した。樹種別では, ミズナラ, ブナ, ミズメなどで間伐効果がみられたが, コシアブラやミズキでは間伐効果はみられずかえって間伐区で枯死木が多かった。ミズナラの後生枝の平均本数と間伐後21年目の林分材積の関係は, 有意な負の相関を示した。林冠を構成する大きな胸高直径階での均等で高い間伐率は, 単木ごとの肥大成長を促進すると同時に, 林分材積が増加することで後生枝の少ない林分へ誘導するものと考えられる。","subitem_description_type":"Other"},{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"一般社団法人　日本森林学会"}]},"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/20.500.12000/46288"}]},"item_1617186920753":{"attribute_name":"Source
