【摘要】 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。更多还原

【Abstract】 This paper has studied the natural regeneration of Broadleaved-Korean pine forest with qualitative and quantitative analysis on the area of Meixi and Chuilan of Xiaoxingan Mountains in 1960. The results of qualitative analysis indicated that there are some close relationship between the states and process of natural regeneration and forest types which are the reaction of the intergrated site conditions.The quantitative studies, utilizing the item-decreased methods of mathematical Model Theory Ⅰ, show that the main factors of influence the natural regeneration of Korean pine under canopies is in this order: forest type, Volume of per hectare, forest tree composition, coverage of understory shrubs and canopy density, etc.The two kinds of methods give us the same conclusion that the forest type is the most important factor of influence the Korean pine regeneration.Therefore, we should combine the quantitatve with qualitative, and neither should be neglected in our research work.更多还原
