本研究針對人工重建造林的5種原生樹種(棒木、光蠟樹、楓香、鳥心石、青剛 棟)進行每本調查等試駿﹒依不同海放高度是不同建度統進行試驗，結果顯示烏心石在海 拔400-750 血有較佐徑生長及高生長，對於坡度的反應也最為明顯，隨著坡度的增加，徑 生長及高生長皆趨於衰退﹒而棒木、光蠟樹A.楓香在10-20. 的坡度上，有顯著最佳的徑 生長典南生長，本研究結果將可提供未來研訂林業改革及後續經營時之重要參考依據。

In this study, five native species (Zelkova serrata, Fraxi1lus griffit侃， Liquidambar formosana, Michelia compressa and Cyclobala1lopsis glauca) were investigatcd, compared and analyzed at different altitudes and different slopes in rehabilitated forests. The results showed that Michelia compressa had better diameter and height growth at 400-750 m, and its growth was obviously affected by slope with growth decreasing as slope increasing. Besides, Zelkova serrata, Fraxi1lus griffithii and Liquidambar formosa1la had the best diameter and height growth at 10-200 slope. The results from this study could provide a guideline for formulation of forest policies and management.
