摘要：以5条天然阔叶米槠林样带为研究对象,研究不同择伐强度(对照、16.97%、17.59%、23.37%、30.63%)对林分及不同林层的断面积生长率、蓄积生长率的影响。结果表明:择伐与对照相比,能够显著促进林分生长,林分断面积和蓄积生长率都随着择伐强度的增加而增加,但不同择伐强度之间差异不明显,与对照差异显著;每条样带中,天然阔叶米槠各林层与全林断面积和蓄积生长率排序均为第III林层>第II林层>第I林层>全林;择伐样带各林层生长率大于对照样带同林层生长率,30.63%择伐强度样带和23.37%择伐强度样带各林层与对照样带同林层生长率差异显著,其余择伐强度样带各林层生长率与对照样带同林层生长率差异不显著。
Five sample forest belts with different selecting cutting intensity （control 16.97%, 17.59%, 23.37%, 30.63%） in natural broad-leaved Castanopsis carlesii forest were established to study the effects on basal area and volume growth rate in stand and tree layers. The results show that compared with the control, the different selecting cutting measures all had significant effects on the stand growth, the growth rates of stand basal area and volume were increased with the rise of selecting cutting intensity, but the growth rates among different selecting cutting intensity stands had no significant differences, and the growth rates between different selecting cutting intensity stands and the control stand all had significant differences;At every sample belts, the growth rate order of basal area and volume was the follows：third tree layer＆gt;second tree layer＆gt; first tree layer＆gt;whole stand;the growth rates of basal area and volume for three tree layers under different selecting cutting intensity were higher than that of the control stand;each tree layer growth rate of sample stand under 30.63%and 23.37%selecting cutting intensity differed significantly with the corresponding tree layer growth rate of the control stand;the tree layers growth rate of other selecting cutting intensity stands had on significant difference with that of the corresponding control stand tree layer.
