摘要

近年來桉樹已成為本省速生樹種中造林最廣的主要樹種。為使桉樹所有者對桉樹林分的生長和未來之收穫有一明確的瞭解，利於經營上的決策，本研究在桉樹分佈較多的地區設置永久樣區44處，進行林分生長之監測工作，並以生長和收穫之數學模式，配合樣區觀測資料，進行地位指數、樹高曲線、單木材積及林分結構等推估模式之配置，以期建立桉樹人工林生長收穫模擬系統，提供經營資訊，並配合經濟分析，協助林主製訂最適經營策略以謀求最大經濟效益。

Eucalptus has recently become the primary fast-growing species that have been planted widely in Taiwan. To aid decision making by stand owners, information regarding stand growth and yield should be provided. To achieve this requirement, this study sets up 44 permanent plots around the island to fit models of site index, height diameter curve, tree volume, and stand structure. By integrating these models, a growth and yield simulator can be established. With this background, together with economic data, the optimal management strategy for the most profitable Eucalptus stands may be designed.
