在总结有关樟子松研究的基础上,根据内蒙古大兴安岭林区相关的统计资料,对樟子松在该林区的天然分布及资源状况进行了调查分析。结果表明:樟子松天然分布集中于该林区的北部,多以片状、斑块状或零散形式生长于阳坡和半阳坡的中上部,斜陡坡居多。天然林资源中,防护林、特用林占90%以上,应以保护为主;近成过熟林所占比例较大,后备资源不足。
On the basis of summarizing the research on Pinus sylvestris var. Mongolica, the natural distribution and resources of Pinus sylvestris var. Mongolica in this forest area were investigated based on the related statistical data of Daxing’anling forest area in Inner Mongolia. The results showed that the natural distribution of Pinus sylvestris var.mongolica was concentrated in the northern part of the forest. Most of the Pinus sylvestris var.mongolica grew in the form of lamellar, patchy or scattered forms in the middle and upper part of the sunny and semi-sunny slopes. Of the natural forest resources, shelterbelts and special purpose forests account for more than 90% of the total forest resources, which should be protected mainly; the proportion of near-mature and over-mature forests is large, and the reserve resources are insufficient.
