| 摘 要： | 采用省级固定样地和伐区调查设计中小班全林每木样地相结合的方法，以天然阔斗林高产大径木林分结构为载体，详细分析了影响该林分结构的三个主要因子：林木最大保留直径（LDT），相邻径级立木株数之比（q）和林分保留断面积（RBA）。分析结果表明，培育大径木的林分结构条件是；LDT不超过54cm，q的取值范围为1．2～1．6，RBA不超过30m^2。

| Abstract: | This paper used the method of combining province-level fixed samples with suboompartment inventory in forest survey and design. Based on the stands structure of natural broad-leaved forest with high-yield large diameter trees, it systemically analyzed three major factors affecting this kind of stands structure: largest diameter tree to leave in stands ( LDT), the relation of the number of trees in one d. b. h. class to the number of trees in the next d. b. h. class (q) and residual basal area (RBA). Research results showed that the condition of breeding the stands structure with high-yield large diameter trees is: LDT less than 54 cm, q between 1.2 and 1.6, RBA less than 30 m2. |
