| 摘 要： | 对草河口地区不同林龄阶段红松人工林抚育间伐后生物量进行了对比试验研究。结果表明，在适宜的间伐强度范围内，平均单株木生物量随间伐强度的减小而减少；林分生物量随间伐强度的减小而增大。

| Abstract: | Proper tending can lead to sound forest structure and
high growth. Biomass of Pinus koraiensis plantation in Caohekou region, with different age
class and tending intensities, were measured and compared in this paper. Analysis made the
points that in reasonable tending extent, average biomass of individual tree under light tending
is lower than that of tree under heavier tending, while the biomass of the stands increased
greater after a more intensive tending felling. For 36yearold plantation under medium tending
intensity, biomass increased 4.17% in nine years. The indices of sound biomass structure of
45yearold forest were(1)1045 the ratio of branch and leaf,(2) 1217 the ratio of leaf and other
organs,(3)19.1 the leaf area index. |
