该文对60年代的小兴安岭美溪、翠峦地区红松阔叶林的天然更新作了定性和定量研究的比较。 定性研究结果表明,红松的天然更新过程及状况与林型有密切关系 而林型是综合立地条件的反映。 定量研究中应用数量化理论Ⅰ的减少项目法,得到影响林冠下红松天然更新的主要因子顺序是:林型、每公顷蓄积量、林木组成、下木盖度、郁闭度等。 两项研究结论一致,即林型是影响红松更新的主要因子。因此,应把定性研究与定量研究结合起来,二者均不可偏废。
In this paper, qualitative and quantitative studies of the natural regeneration of Korean pine broad-leaved forest in the Meixi and Cuiluan Mountains in the Xiaoxing’an Mountains of the 1960s were made. Qualitative research results show that the natural regeneration process and status of Korean pine is closely related to the forest type and the forest type is a reflection of the comprehensive site conditions. Quantitative research using quantitative theory Ⅰ reduction project method, obtained under the canopy of Korean pine natural regeneration of the main factors are: forest type, per hectare volume, forest composition, understory cover, canopy density. The two studies conclude that the forest type is the main factor affecting the regeneration of Korean pine. Therefore, qualitative research should be combined with quantitative research, both of which should not be neglected.
