1. 疏伐經九年後，對林下光環境仍有影響，且對變異程度的影響大於 光立地係數的影響。
2. 結果顯示疏伐九年後影響仍在，但此差異已遠小於剛疏伐完後的 差異，且部分差異可能與疏伐無關而與森林自然更替有關。
3. 疏伐樣區記錄到之林下植物物種數較多，但三種不同疏伐樣區的 林下植物組成仍以冷清草和廣業鋸齒雙蓋蕨為主，再加上自然更 替讓未疏伐樣區有類似疏伐的處理，所以三種不同疏伐程度樣區 的林下植物多樣性沒有顯著的差異。
4. 散射光立地係數與林下植物物多樣性之間有顯著正相關，可能因 為研究區多雲霧，光照量低，故林下植物樣性與光照呈正相關。而 多雲霧可能使得直射光立地係數未能反應真的直射光量，造成散 射光立地係數較直射光立地係數更能反應真實的日輻射大小。
5. 木本植物的部分，不同疏伐強度樣區的木本植物群落相似性均高，
組成仍以柳杉為主，柳杉的優勢度仍最高。但隨疏伐程度越高柳杉 優勢度越低且多樣性有越高的趨勢。
