摘要: 本研究旨在探討柳杉人工同齡林之樹冠特性及評估柳杉人工林疏伐五年後之效益。研究地區位於台灣中部地區巒大事業區第74林班之柳杉人工林,該林分於2004年劃設為疏伐示範區,當時林分之林齡為33年生,為瞭解林分疏伐前之特性,本研究依直徑級進行分層取樣共選取樣木20株,以了解不同直徑級之樹冠特性,並建立樹冠外部形態 (Out crown radius, OCR)模式。樣木在伐倒後測量不同高度的冠層特性,分別測量樣木之樹冠參數,並探討胸徑 (DBH)與樹冠參數之相關性,其包括活樹冠比 (CR)、樹冠長 (CL)、相對樹冠長 (RCHi)、不同冠層高之樹冠半徑 (RBi)等,以作為OCR模式之基礎,所建立本區域柳杉之OCR模式為: OCRi=(0.32+13.77×CR) ×[(RCHi-1) ÷(RCHi+1)]+(-3.75-0.04×DBH-8.98×CR) ×(RCHi-1) ,其迴歸式之R2=0.92,同時為檢測模式之適用性,採用MAPE (Mean Absolute Percentage Error )探討其誤差量,各直徑級之MAPE介於14.97-27.15%,顯示模擬效果良好。 本研究在2009年進行調查並分析疏伐後5年之效益,研究結果顯示,林分經疏伐過後,可以促進其生長率及樹冠發展,其中上層疏伐35%之林分,能夠促進林分之基本性態值(DBH、BA、V及碳貯存量)之增加率;下層疏伐45%則具有較大之空間效益,其CPA顯著大於其它疏伐處理之林分,能有效促進樹冠之發展。本研究所得之結果,將可作為柳杉人工林樹冠發展之基礎,提供柳杉人工林疏伐作業之參考。
This study aimed to understand the relationships between the crown characteristics and crown shape and to evaluate thinning effects of a Japanese cedar (Cryptomeria japonica D. Don) plantation in the Luan-Da Working Circle of central Taiwan. I employed stratified sampling method by utilizing the diameter class. The stand was divided into five stratifies, with 4 trees in each diameter class, respectively. That is, 20 trees were sampled in total. Six crown parameters were analyzed including crown radius (RB), length (CL), relative crown height (RCH), diameter at breast height (DBH), and live crown ratio (CR). Using stepwise regression analysis, I found out crown radius (OCR) model best estimated the crown shape, with R2 equaled to 0.92. The equation was illustrated as below: OCRi=(0.32+13.77CR) [(RCHi-1) (RCHi+1)]+(-3.75-0.04DBH-8.98CR) (RCHi-1) In addition, the Mean Absolute Percentage Error (MAPE) showed good forecasting to the OCR model, with the range of MAPE was 14.97-27.15%. The findings revealed that the OCR model can be used to effectively assess the crown shape. The study investigated the stand 5 years after thinned. The results showed that thinning had positive effects on the growth rate (%) and crown development. The findings revealed that 35% of above thinning treatment increased the growth rate of DBH, basal area, volume, and carbon storage, while 45% of below thinning treatment has effects on space that crown projection area was significant larger than stands of other thinning treatments. The results can also provide foundation regarding the thinning information for Japanese cedar plantation management.
