通过以马尾松人工林为研究对象,对其生物量转化与扩展因子、根茎比、木材基本密度及变化规律等进行分析.结果表明:(1)马尾松人工林的BCEF值为0.62Mg·m-3,BCEF值幼龄期变动较大,并随树龄增大趋于稳定值;(2)马尾松人工林的BEF平均值为2.36,BEF随树龄的增大,并呈指数降低并趋于稳定;(3)马尾松人工林R平均值为0.202,新造林根茎比值最大,并随着年龄的增大趋于稳定.

Biomass conversion and expansion factor, ratio of root and stem, wood basic density ofPinus massoniana plantation were analyzed. The results showed that BCEF ofP. massoniana plantation was 0.62 Mg·m-3,which changed with age increasing, tending to a stable value; The BEF average was 2.36, increasing with forest age, decreasing exponentially and tended to be stable; The average of R was 0.202, new ratio of root and stem reached its maximum, tending to be stable with age.
