论文从5个方面对长白山云冷杉阔叶红松林进行了研究。①研究了主要树木的心腐规律。红松心腐存在反常现象,小径木的心腐率显著地高于大中径木;②研究了主要树木的高生长过程,分析了群落环境的变化对树木高生长过程的影响并根据得到的结论阐述了在红松林宜林地营造所谓“速生”落叶松纯林的错误之处;③分析了主要树木的年龄结构和径级结构并研究了不同树种年龄与胸径之间存在的数学关系,以此为基础,结合种内种间关系的分析,阐明了云冷杉阔叶红松林不同树种的更替规律;④通过对若干类型红松
The paper studied the broadleaved Korean pine forest in Changbai Mountains from five aspects. ① studied the law of the heart of the main trees. The anomalous state of the core of red pine is anomalous, the rate of heart rot of the small-diameter wood is significantly higher than that of the medium-large-diameter wood. ② The high growth process of the main trees is studied, the influence of the change of the community environment on the high growth of the trees is analyzed, The conclusion expounds the mistake of creating the so-called “fast-growing” pure larch plantation in the forest of Korean pine forest. ③The age structure and the diameter structure of the main trees are analyzed and the mathematical relationship between the age and DBH of different tree species is studied. Based on this, combined with the intraspecific relationship analysis, the law of replacement of different tree species in the broad-leaved Korean pine forest was clarified.
