% に過ぎず，森林への遷移は部分的なものに留まっていると結論された。これに対して，ゲレンデの36 %，33 % および5% を占めるススキ群落，タニウツギ群落，オオイタドリ群落の3群落タイプについては，高木性木本類およびそれらの実生の出現数が極めて少なかった。一般化線形モデルを用いた解析結果から，侵入を困難にしている要因は高い上層被覆率と厚いリター層であると結論された。一般にススキ群落では，上層の被服率が小さいため，群落内への光の透過が大きく，木本植物が侵入しやすいといわれる。しかしながら，本調査地のススキ群落には上層や中層にオオヨモギが侵入しており，その遮光によって高木性木本の更新が阻害されたと考えられる。さらに本調査地ではリター層が更新阻害要因となっていたが，その厚みはススキ群落とオオイタドリ群落において大きかった。すなわち本調査地では，ススキやオオイタドリを主体とする高茎草本群落における高木性木本の更新は停滞しており，速やかな森林回復の可能性は低いと判断された。","subitem_description_type":"Abstract"}]},"item_10_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_10_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"信州大学農学部AFC報告
