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8～12 a、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 appropri- ate felling age was 8 - 12 years old and the average DBH of the stand was 5 -7 cm.
