つの段階が検出された。1 ）伐採後18 年を経た段階では，萌芽由来の照葉樹林型高木種が林冠を優占し，伐採直後に優占していた先駆種は，林冠に到達した萌芽個体の被圧によって消失したと考えられた。2 ）伐採後23 -46 年では，林冠個体の多幹率（全個体に対する多幹個体の割合）と平均幹本数，そして実生由来の下層個体の数が減少しており，林冠が閉鎖したために，劣勢な幹の自然間引や実生の定着阻害が起きたと考えられた。3 ）伐採後60 年を経過する段階から萌芽由来の林冠個体が減少しており，株内での幹の競争により単幹化した個体で枯死が発生していることが示唆された。同時に林床の実生も増加しており，林冠個体の枯死に伴う林冠ギャップの形成と林冠構造の複雑化により林床の光環境が好転し，再び実生が侵入したと考えられた。","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_6_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"日本森林学会","subitem_publisher_language":"ja"}]},"item_6_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.4005/jjfs.90.46","subitem_relation_type_select":"DOI"}}]},"item_6_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13498509","subitem_source_identifier_type":"PISSN"}]},"item_6_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA12003078","subitem_source_identifier_type":"NCID"}]},"item_6_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"650","subitem_subject_scheme":"NDC"}]},"item_6_version_type_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"井藤,
