白栎次生薪炭林的工艺成熟与适宜采伐年龄

摘要

通过测定不同年龄杆材燃烧值及林分胸径生长,对都匀地区白栎薪炭林的工艺成熟结合经济效益进行初步分析,初步确定该地区白栎次生薪炭林的采伐年龄在达到8 ～12a、林分平均胸径达到5～7 cm时为宜.%The craftwork of secondary fuel-wood forest of Quercus fabri in Duyun area, as well as the economic benefit was analyzed through measuring fuel-wood combustion value and average DBH growth of the stand at different ages in the present work. Felling age of secondary fuel-wood forest of Quercus fabri in the area was preliminarily determined according to the craftwork maturity and the economic benefit analysis. The appropriate felling age was 8 ~ 12 years old and the average DBH of the stand was 5 ~7 cm.
