红松人天混交林不同的抚育方式、抚育强度对红松生长和林分质量有影响。通过综合评估,对上层阔叶树实行中高强度透光疏伐效果较好,能分别提高红松胸径生长量26.3%和34.8%,提高树高生长量17.1%和11.5%,提升珍贵阔叶树在阔叶树中比例6.5%和10.1%;在相同透光强度下,窄带透光抚育和均匀透光抚育效果近似,是均可采用的2种抚育方式。
The different tending ways of mixed plantation of Pinus koraiensis and the growth of Pinus koraiensis had influence on the quality of Korean pine. Through comprehensive evaluation, the effect of medium and high intensity light-transmutation on the upper broad-leaved tree is better, which can increase the DBH growth of 26.3% and 34.8%, increase the height growth of tree height by 17.1% and 11.5% respectively, and increase the proportion of broad- 6.5% and 10.1%, respectively. Under the same light transmission intensity, the narrow-band light-transmission and uniform light-transmission were similar, which could be used in both ways.
