摘要

本文旨在探討42種原生樹種之生長，生長資料調查自惠蓀林場第1林班之原生樹種園，採用Mitscherlich生長模式及Schumacher生長模式模擬林木之胸高直徑生長過程，並以變方分析及最小差異(LSD)多變域分析比較平均胸高直徑平均值的差異。由兩種生長模式將原生樹種區分為三種生長形態，其中以遞增生長型佔22種為最多。樹種平均生長量經變方分析呈顯著後，以LSD多變域分析可用以比較樹種間平均值之差異性。而生長形態與胸高直徑平均生長量之關係並無明顯的相關性。本研究所得之結果將可做為原生樹種之基礎參考資料。

The purpose of this study was to discuss juvenile period tree growth of 42 indigenous tree species. Data were inventoried from indigenous-tree garden at Compartment no. 1, Huisun Forest Experimental Station. The Mitscherlich growth model and the Schumacher growth model were used to simulate DBH growth process of each tree species. The ANOVA and LSD were applied to compare the means among varied tree means DBH of tree species. After simulating tree growth, three growth types were sorted by two growth models. Among those growth types, 22 tree species belong to the concave growth type, which is major Mean DBH among tree species could be distinguished by LSD, when ANOVA appeared significant. The relationships between growth type and mean DBH, it seems that they were no significant difference. The results will provide foundational information for indigenous tree species.
