摘要
为促进高寒兰采林区油松林天然更新,本研究在兰采林区选设12个天然更新标准地,采用数量化理论Ⅰ对油松林天然更新的影响因子进行分析,评价影响油松林天然更新的因素。结果表明:影响油松林天然更新的主导因子是坡向。油松林天然更新在阴坡、下坡位、20%~40%灌木盖度、斜坡的林地天然更新好。该研究结果可为兰采林区开展油松林天然更新修复提供科学的理论依据。
In order to promote the natural regeneration of Pinus tabulaeformis Carr.forest in alpine Lancai forest region,12 natural regeneration standard sites are selected in this region.The influencing factors of Pinus tabulaeformis Carr.natural regeneration are analyzed by quantitative theory I so as to evaluate the affecting factors.The results show that the dominant factor affecting the natural regeneration of Pinus tabulaeformis Carr.is slope aspect.The natural regeneration of Pinus tabulaeformis Carr.is good in shady slope,downhill position,20%~40%shrub coverage and slope forest land.The results can provide a theoretical basis for natural regeneration and restoration of Pinus tabulaeformis Carr.forest in Lancai forest region.
