中文摘要 | 本文以紅繪人工同齡林疏伐林分為材料,旨在闡釋Richards生長模式在疏伐林分 單木生長之效應,經採用三參數之Richards生長模式模擬單木之胸高斷面積、樹高及材積 生長,所得之結果如下:(1)就胸高斷面積及材積而言,疏伐會促進生長潛能值(B□),但卻 會提早最大生長速率(t□)之發生時間。(2)疏伐可以促進單木材積之同化作用及異化作用速 率。(3)胸高形數並不會因疏伐處理而產生明顯之差異。 |
英文摘要 | The objective of this study was to interpret the simulation effects of individual tree growth using the Richards growth function. Data were collected from an even-aged stand of thinned Chamaecyparis formosensis plantations. The three-parameter Richard's function was applied to individual tree basal area, height, and volume growth. (1) Thinning can increase B□ (growth potential) but decrease t□ (the time of maxium growth rate) of tree basal area and volume. (2) Thinning can improve individual tree anabolic and catabolic rate rates. (3) From factors have no significance difference by tinning treatments. |
